Why are our bones strong and tough, why are our teeth hard? How do mussels and snails build their shells? Why can bacteria and birds navigate in magnetic fields? The lecture attempts to give answers to these questions: in all cases a biological function, such as support, protection or orientation, is served by composites of organic materials and inorganic crystals – biominerals – that form inside the living organism (MANN, 2001). The sizes, shapes, compositions, structures and arrangements of the mineral grains in the organism are all tightly controlled by various biological mechanisms that affect crystal nucleation and growth (Fig. 1). The highly constrained properties of biominerals distinguish them from their inorganically-formed counterparts. The study of biominerals uses research techniques and knowledge from several disciplines, including mineralogy, biology, physics, materials science and geology. In this lecture, we will employ a cross-disciplinary perspective to broadly review the functions, formation mechanisms and properties of biominerals.

Figure 1. Two pairs of chains of magnetite (Fe3O4) nanocrystals in the cell of a magnetotactic bacterium. The white lines represent a map of the magnetic induction, as obtained from electron holography in a transmission electron microscope, while the colours show the direction of the magnetic induction according to the colour wheel shown in the lower left. The highly constrained sizes, shapes and orientations of the ferrimagnetic nanocrystals result in a uniform magnetization along the chains, enabling the cell to swim parallel to the Earth’s magnetic field.

Welcome to Conference Participants

The organising societies and the organising committee warmly welcome the participants of the MinPet2009 & 4th Mineral Sciences in the Carpathians Conference, the joint meeting of two traditional meeting series (the biennial MinPet and the triennial MSCC). Some 170 colleagues from 17 countries of Europe and beyond registered at the meeting. Most of the participants of the conference are, as a matter of course, from the countries of the Alpine–Carpathian–Pannonian Region. Therefore, our assembly is well aware that, as the invitation formulated, from mineralogical and geochemical points of view this region is among the most interesting and complex areas of Europe. It is to be hoped that the present meeting, by giving an insight in the state of art of mineral sciences in the region, will help colleagues working in other parts of the world to realise this uniqueness. In this way the MinPet2009 & 4th MSCC Joint Conference may become an important preparatory step of the IMA 2010 General Meeting (Budapest, August 2010), the quadrennial world conference now jointly organised by the countries of the Alpine-Carpathian-Pannonian Region.

SCIENTIFIC PROGRAMME

The scientific programme covers mineralogy, geochemistry, crystallography, petrology and mineral deposits, as well as their applications, with special emphasis on the broad sense Alpine–Carpathian–Pannonian Region. Some 60 contributions are presented in the oral and 110 in the poster sessions, fruits of the research activity of some 380 authors and co-authors altogether. Five plenary presentations report exciting new results from different fields of our science. A public lecture on the emerging research field of biominerals is intended to attract audience from all disciplines of science.

VENUE

The Conference is held at the Danube Riverside Campus of the Eötvös Loránd University, Building C (see p. 28 for the campus map and the opposite inside back cover page for a map of the conference area within Building C).

Department of Mineralogy, Eötvös Loránd University, has proved to be a well-tried venue of several scien-tific meetings in the past 15 years. The Eötvös University, celebrating the 235th anniversary of its organised min-eralogical education and the 160th anniversary of the founding of the independent Department of Mineralogy, offers a friendly environment also for the current conference. Participants will have the opportunity to visit the 235-year-old Mineral Collection (saved in its historical 19th century form), venue for the ice breaking party.

The Danube Riverside Campus of the Eötvös University is close to the heart of Budapest. Architectural monuments, museums, shops are easy to reach from here. A week in Budapest may give a pleasant tourist experience also to the accompanying guests.

SEE YOU AGAIN AT IMA 2010!

ORAL PRESENTATIONS

The non-plenary oral presentations run concurrently in two parallel sessions. Room A (Rooms 0-823, respectively 0-822): mineralogy-related presentations, Room B (Rooms 0-803, respectively 0-804): geochemistry-petrology-related presentations. (See inside cover for a detailed, tabulated overview)

Length of the oral presentations: 20 minutes (15 minutes talk + 5 minutes discussion)

Uploading time: Uploading talks from a USB stick or CD is suggested to be completed on the day prior to the talk in the speakers’ room (see map on inside back cover). Late speakers can upload their files directly in the lecture room the latest 20 minutes before the start of the session. (A technician will be present in the room.)

Notes:1) Presentations containing special features (movies, animations etc.) should be checked due time prior to the session.2) Speakers wishing to present their talks from their own Apple Computer should ensure that their machine has got the

appropriate VGA connector and it will work appropriately with the data projector at the conference site.3) Unless special technical conditions require, it is not possible to present talks using a speaker’s PC laptop, as this

disrupts the smooth running of the session.

POSTER PRESENTATIONS (see map on inside back cover for location)

Posters can be put up on the assigned board during the registration period: Monday, 1 pm – 9 pm and Tuesday 8 am – 8:45 am. Posters will be on display during the whole conference and should be removed on Thursday 4:50 pm – 6:30 pm.

Posters are arranged by sessions, see pp. 7–13 for your poster code. Pins to attach posters to the board will be supplied.

All breaks and the two dedicated poster sessions (with no concurrent oral session, September 8, Tuesday, 2 pm – 4 pm and September 10, Thursday, 2:30 pm – 5 pm) can be used for poster discussion. Poster presenters are expected to indicate their presence at their poster on the time table provided by the organisers to each poster board right after mounting of the posters.

CONTOURS OF A NEW THEORY ON CRYSTAL DISSOLUTION

Luttge, A.1 & Arvidson, R.S.1

1Rice University, Department of Earth Science MS-126, 6100 S. Main St., Houston, Texas 77005 USA


We discuss current progress in the theoretical and empirical treatment of crystal dissolution.Our approach abandons the limitations of closed-form equations and conventional “rate laws”and moves forward to a treatment of crystal reaction kinetics as a dynamic, many-bodyproblem that must be solved stochastically. At the centre of our model is a fundamentalunderstanding of the kinetics at kink sites that govern the overall processes of both crystaldissolution and growth (Fig. 1).This change in treatment brings with it important consequences: it permits a morefundamental insight into the molecular surface processes and their cumulative result,including variation of rate within mineral systems, the effect of non-stoichiometriccompositions, the relationship of ordering and temperature, and related phenomena. Theseinsights potentially lead to a comprehensive theory of crystal dissolution and a unifieddissolution-growth theory. However, they also require conceptual revisions in our approach toproblems involving crystal-fluid interaction. First, we must re-examine our application of theconcept of reactive surface area that has proven to be a largely unquantifiable parameter.Second, we must reconcile the lack of a single or “true” value for a so-called “rate constant”.Instead, we suggest that a range of possible rates exists for any given mineral, with a certainprobability for any given rate within this range. These insights have significant implicationsand consequences for our ability to predict long term behaviour in systems of environmentalimportance, such as nuclear waste, corrosion, and weathering of rocks and soils, with furtherimplications for water quality and climate development.

CRYSTAL CHEMISTRY OF LIGHT ELEMENTS IN MAJOR ROCK-FORMINGMINERALS

Robert, J.-L.

IMPMC, 140 rue de Lourmel, 75015 Paris, France

e-mail: Jean-Louis [email protected]

Light elements (Z < 10) play a major role in rock-forming minerals. Their presence has oftenbeen ignored in the last decades, because they are hardly detectable in standard EMPA. Thedevelopment of new analytical facilities, like EMPA with multi-layer detectors, SIMS,nuclear and vibrational methods, combined with local charge balance considerations led to therecognition of light elements as important constituents of major rock-forming minerals. All ofthem, besides nitrogen, have a constant valence state under naturally occurring conditions.Light elements are not randomly distributed. Local associations of two to three of them arefrequent. For example, we find that the replacement of OH– groups by F– in layer, ring anddouble-chain silicates favours the incorporation of Li+ in the structure.The behaviour of Li+ is interesting since its coordination ranges from tetrahedral in lab-prepared compounds, like sulphate and tungstate, to highly distorted 12-fold coordination inclinoamphiboles. In clinoamphiboles, Li+ can occupy M1 and M3 sites, replacing a divalentcation, as well as the pseudo-cubic M4 site, and also the large [12]A sites. It is also common in[6] coordination in lepidolites, where it collapses the miscibility gap between trioctahedraland dioctahedral micas, and as an interlayer element in layer silicates, where it can occupy atleast two types of six-fold coordinated sites.Another relevant light element is F, which frequently replaces the hydroxyl group in OH-bearing minerals, silicates (micas, amphiboles, tourmalines etc.), and phosphates. It enhanceslocal ordering and is depolymerising under magmatic conditions. The commonly admitted Fe-F exclusion is violated in many minerals, e.g. fluorannite, and buergerite. F– can also bepresent as an interstitial anion, in high-Si micas having a partial dioctahedral character, whichfrequently led to the rejection of analyses as for “too high F content”.Boron can occur in [3] and [4] coordinations. B3+ can replace Al3+, as a major element infeldspars like reedmergnerite, the boron equivalent of albite. The three-fold coordination ofB3+ is usual in tourmalines generated under low P and T conditions, but [4]B3+ is also knownin high-P metamorphic tourmalines related to olenite. Beryllium would deserve a systematicanalysis, in major rock-forming crustal minerals, typically in pegmatites and derivedmetamorphic rocks. The [4]-coordination of this divalent cation generally generates strongshort-range ordering.Nitrogen as a major element has the most interesting properties as N5+, i.e. as ammoniumcation, yields few proper phases (e.g. tobelite). It can seriously modify the swelling propertiesof clays and their ability to trap pollutants in waste deposits.Finally, hydrogen, the most abundant element in the Universe, is obviously present in hydrousphases (as OH groups and/or water). It frequently compensates local charge defects innominally anhydrous minerals, from the Earth mantle to the surface.

MAGNESIUM PHOSPHATES: FROM MOLECULAR STRUCTURES TOSTRONGLY CONDENSED MINERALS

Armbruster, T.

Mineralogical Crystallography, Institute of Geological Sciences, University of Bern, Freistr. 3, CH-3012 Bern,Switzerland


Magnesium-phosphate minerals are structurally very special because in contrast to calciumphosphates they comprise on one hand highly hydrated molecular structures, in which PO4

units are kept in position by hydrogen bonds originating from Mg(H2O)62+ octahedra, and on

the other hand they form densely packed orthophosphate structures. As examples for highlyhydrated minerals, structure and formation conditions of e.g., cattiite ((Mg(H2O)6)3 [PO4]2 � 4H2O, CATTI et al., 1981; BRITVIN et al., 2002) and struvite (Mg(H2O)6NH4[PO4],FERRARIS et al., 1986) are discussed. As examples of densly packed magnesium-phosphateminerals, special emphasis is placed on the modulated series of triplite–wagnerite groupminerals (ARMBRUSTER et al., 2008). The space group for wagnerite (Mg,Fe)2PO4(F,OH)was considered to be P21/c with a = 9, b = 12.6, c = 11.9 Å, � = 108° until REN et al. (2003)reported a new polytype (space group Ia, a = 9, b = 31.5, c = 11.9 Å, � = 108°) namedwagnerite-5b as it has a five-fold superstructure along b relative to triplite Mn2PO4F andzwieselite Fe2PO4F (space group I2/a, a = 9, b = 6.5, c = 12 Å, � = 106°). Single-crystal X-ray and chemical data were obtained on 38 wagnerite samples (ARMBRUSTER et al., 2008)formed under conditions ranging from near surface in sediments to high temperatures(granulite facies) and ultrahigh-pressures. We found five “pseudo”-commensurate modulatedstructures (polytypes) in decreasing abundance: 5b (21 examples), 2b (12), 7b (3) and 9b (2)and 3b (1). Five additionally studied triplite–zwieselite samples from pegmatites showed the1b type structure. The crystal structures of all 6 polytypes have been refined from single-crystal X-ray data and imaged by HRTEM. The main structural difference among the variouspolytypes is modulation of the (F,OH) arrangement giving rise to different space groups andperiodicity along b. F-dominant triplite–zwieselite (mean octahedral radius: > 0.79 Å) has the1b polytype. The 5b polytype prevails in F-dominant, Fe,Mn-rich wagnerite (mean octahedralradius: 0.74-0.79 Å) and in Mg-rich samples (octahedral radius = 0.72 Å) with near F end-member composition. The single 3b wagnerite plots among the 5b samples but close to thetriplite–zwieselite (1b) boundary in terms of XF and mean octahedral radius. Mg-richwagnerite (octahedral radius = 0.72–0.73 Å) is characterized by the 2b polytype, whatever theOH content. 7b and 9b polytypes are found for compositions stradling the boundary of the 5band 2b fields with XF between 0.84 and 0.98. These broad relationships suggest a major rolefor compositional control in determining modulation periodicity.

CATION ORDERING IN SILICATES AS SHOWN BY ELECTRONCRYSTALLOGRAPHY

Dódony, I.

Department of Mineralogy, Eötvös Loránd University, Pázmány Péter sétány 1/C, H-1117 Budapest, Hungary


The structure of many minerals cannot be measured using conventional single crystaltechniques due to their polycrystalline and fine-grained character. That is why non-conventional methods of structure analysis must be applied to obtain structural informationfundamental to the understanding of these minerals. Electron crystallography is a powerfulmethod for solving structures of crystals with sub-micrometer sizes that are too small for X-ray crystallography.Compared to X-ray crystallography, the main advantage of electron crystallography is thatthere is no so-called “phase problem” in it. We can retrieve the phases from Fourier-transformhigh-resolution images. One of the main advantages of electron crystallography over X-raysis that the phases of crystallographic structure factors can be obtained directly from HRTEMimages when the crystal is thin enough to almost satisfy the kinematic approximation.Electron crystallography operates in both real and reciprocal space, phase informationobtained from high-resolution transmission electron microscopy images can be incorporateddirectly into the deconvolution process of the projected charge-density map of the measuredobject.Electron diffraction (ED) patterns can also be used alone for structure determination, wherethe structure factor phases are determined by direct methods.As an example, a study of ordered and disordered substitution in pyrope is presented. Oneapproach to the crystallography of solid solutions is to use high-resolution transmissionelectron microscopy together with electron crystallography, a combination that has thepotential of resolving individual atomic species and, more commonly, their projectedcolumns. Focus will be given to both theoretical and experimental considerations fordetermining substituted positions in HRTEM images and the reliability of suchdeterminations. We do this using pyrope garnet, chosen because it is an important rock-forming silicate with several possible crystallographic sites for substitutions. Usingsimulations with realistic constraints of composition and experimental conditions, wedetermine and demonstrate the abilities of electron crystallography for the characterization ofboth random (i.e., non-periodic) and ordered (periodic) substitutions in a complex silicate.As another example, modulations both in the tetrahedral and octahedral sheets in antigoritestructure were studied using the unique opportunities of electron crystallography. The resultsclearly show the lack of four- and eight-membered silicate rings in the tetrahedral sheets forthe antigorite structure model supposed by KUNZE (1958).

HYDROUS DEFECTS IN PYROXENES

Stalder, R.

Institut für Mineralogie und Petrographie, Universität Innsbruck, Innrain 52f, A-6020 Innsbruck, Austria


Pyroxenes are amongst the most important rock-forming minerals in terrestrial planets and,next to olivine, the most abundant constituents of the Earth’s upper mantle. Due to the abilityof pyroxenes to incorporate significant trace amounts of hydrogen as point defects (i.e.,distinctively higher amounts than other upper mantle minerals) they may be regarded as majorhosts for hydrogen in the upper mantle. Since the incorporated hydrogen has majorconsequences for the physical properties and mantle processes such as melting, the exactknowledge of incorporation and dehydration behaviour is of general interest in geochemistry,petrology, mineral physics and geophysics.In order to quantify the water content of nominally anhydrous upper mantle minerals, twomain strategies have been followed: (1) direct analyses of samples derived from upper mantlerocks (mostly xenoliths from volcanic rocks from the Earth’s mantle), which show watercontents around 200 wt. ppm H2O for orthopyroxene and around 400 wt. ppm H2O forclinopyroxene (GRANT et al., 2007); (2) high-pressure – high-temperature experiments,investigating the effect of pressure, temperature, oxygen fugacity, silica activity and otherchemical aspects on water incorporation. Water contents in the mineral phases observed bythis strategy are generally much higher than observed in natural samples, and for pyroxenescontents up to several thousand wt. ppm H2O have been observed (MIERDEL et al., 2007).Several interpretations for the gap between analysis of natural material and experimentalresults have been put forward: (1) Partial hydrogen loss during ascent to the Earth’s surface(MACKWELL & KOHLSTEDT, 1990), (2) interaction of different hydrous defects incomplex composed systems (STALDER et al., 2005) and (3) reduced water fugacity innatural systems (STALDER et al., 2008). In spite of steadily growing evidence for point defects in pyroxenes, indications for planardefects have hitherto not been found. However, some orthopyroxenes (both natural andsynthetic ones, but all with high amounts of Al) show features similar to hydrous phases, suchas chlorite. One possible interpretation is the survival of chlorite-like domains inorthopyroxene far beyond the stability field of chlorite, similar to OH-bearing humite-typelamellae, which survive in some mantle rocks well beyond the stability field of humite asplanar defects in olivine (HERMANN et al., 2007).

NANO-SIZED MINERALOGY OF A TOARCIAN MANGANESE DEPOSIT (ÚRKÚT, HUNGARY) AND THE IMPORTANCE OF Mn3+ IN ITS GENESIS

Cora, I.1 & Weiszburg, T.G.1

e-mail: [email protected] Úrkút (Hungary) hosts the largest Toarcian Mn ore deposit in Europe. It consists of both carbonate and oxide ore sequences. We studied a complete carbonate profile, consisting of a black shale sequence with two Mn-bearing horizons. This is the first time when this very fine-grained (µm- and nm-sized), lamellar sedimentary sequence was traced by systematic, real micrometer scale studies, including structural (micro X-ray diffraction), textural, and chemical (SEM+EDS, cathodoluminoscope) observations, as well as TEM+ATEM characterization of the nm sized phases. These data contribute substantially to the earlier genetic models. The lamellar ore structure is a result of parallel or exclusive existence of phases recording redox conditions (and their changes). Mn occurs both in carbonate (Ca-rich rhodochrosite) and (recently subordinate) oxidic phases in the carbonate ore. Ore-forming carbonate minerals display a complex texture. Six different types of Mn-Ca carbonates were identified. The oxidic Mn phase of the carbonate sequence is manganite. In contrast to the assumptions of the previous genetic models no Mn4+-oxide phase was found. Fe occurs both in reduced and oxidized form (euhedral and, in limited layers, framboidal pyrite; goethite and sheet silicates). Manganite can be regarded as the primary ore accumulation form of Mn. As Mn3+ is not expected to be formed by bacterial activity, manganite may be a chemical precipitate formed during local oscillation of suboxic/oxic conditions near the seabottom in the general Toarcian anoxic/suboxic environment conveying continuously dissolved Mn2+ into the local system. In restored local suboxic conditions microorganisms could utilize first Mn3+, then Fe3+ when oxidizing organic material. With increasing concentration of Mn2+

aq and HCO3aq(org), fine grained Ca-rich rhodochrosite precipitated, and allotigenic calcite, such as Radiolarian pseudomorphs, was also metasomatised by Mn2+. This two-way Ca-rhodochrosite formation model explains the typical intermediate 13C values (~15‰) and the poor correlation between Mn and 13C values published earlier (Polgári et al., 1991). Zeolite present in the sequence is detrital and cannot be regarded as a direct marker for any potential volcanic activity (source of Mn). POLGÁRI, M., OKITA, P.M., HEIN, J.R. (1991): J. Sediment.

NEW MINERALOGICAL DATA FROM THE ENVIRONS OF MÁD, TOKAJ MTS., HUNGARY

Menyhárt, A., Dódony, I. & Pekker, P.

Department of Mineralogy, Eötvös Loránd University, Pázmány Péter sétány 1/C, Budapest, H-1117 Hungary

e-mail: [email protected] Several mines are known in the hydrothermally altered rhyolite tuff in the environs of Mád, Tokaj Mts., NE Hungary. This study presents new data on mordenite and clinoptilolite, rectorite, iron oxide, halloysite, smectite and SiO2 phases from these mines. X-ray powder diffraction (XRPD), scanning (SEM) and transmission electron microscope (TEM) techniques were used to identify minerals and gain more details on their occurrence. The X-ray powder diffraction study of a sample from the Bomboly area indicates rectorite (as was known earlier), however, TEM images show only separate illite and smectite crystals without any evident structural connection among them. The zeolite minerals were identified on the basis of sets of their d(hkl) values and symmetries measured on selected-area diffraction patters. Their compositions were quantified simultaneously using energy dispersive X-ray (EDX) spectra acquired on the corresponding areas. The hydrothermally altered rhyolite tuff at Harcsa-tet Hill contains a Na-free, Ca-containing zeolite, which corresponds to mordenite according to XRPD results, whereas at Suba-oldal area clinoptilolite occurs with additional Mg and K as exchangeable cations. At Suba-oldal smectite and a SiO2 phase can also be found. Using TEM the thickness of the individual smectite flakes was determined and the SiO2 phase was identified as cristobalite. Király Hill was identified as a new locality of halloysite. An unusual iron oxide/hydroxide phase that has earlier been considered as hematite/ hydrohematite was recognised at Király Hill Although its XRPD diagram shows reflections interpretable as hematite, according to TEM data neither its structure nor its chemical composition comply with that of hematite.

e-mail: [email protected] In recent years, spectroscopy is increasingly being used to study mineralogical samples on a micrometre scale. Failure to consider critically the sample volumes analysed, however, may result in serious misinterpretations of results (for instance, see discussion by NASDALA, 2009). In a recent contribution, PICOT et al. (2008) described monazite samples that were irradiated with 1−7 MeV Au ions. They found in the TEM that near-surface volumes areas were fully amorphised, whereas Raman spectra still showed narrow, “crystalline” PO4 vibrational bands. PICOT et al. (2008) concluded that phosphate groups must be remarkably irradiation-resistant units that remain undamaged in spite of the bulk amorphisation. We believe this conclusion is incorrect; simply caused by the failure to consider the real depth resolution of the Raman analysis system used. Monte Carlo simulations predict that the irradiation of monazite done by PICOT et al. (2008) resulted in a damaged layer of not much more than 1 µm thickness (Fig. 1a). Given the real depth resolution of modern confocal Raman systems (≥2 µm), it appears more than likely that PICOT et al. (2008) also analysed the underlying, undamaged host monazite as well as the irradiated layer. We report first results of our experiments, which were done analogous to those of PICOT et al. To rule out the above uncertainty, however, we used ∼1 µm thick monazite foils (Fig. 1b) that were prepared using a focused ion beam system and placed atop a “Raman-inert” sample holder.

TEM STUDY OF AMORPHOUS IRON OXIDE PRECIPITATES FROM THE MÁTRASZENTIMRE Pb-Zn ORE MINE, MÁTRA MTS., HUNGARY

Pekker, P., Dódony, I. & Weiszburg, T. G.


e-mail: [email protected] Amorphous and nanocrystalline iron oxides are very common in acid mine environment, originating from the decomposition of iron sulfide (pyrite). Our samples originate from the precipitate of the acid mine drainage of a Pb-Zn ore mine near the village Mátraszentimre (Mátra Mts., North Hungary). The fresh bulk sample looks like a red jelly consisting of solid iron oxide/hydroxide and electrolite of water-soluble ions (pH 6.7, Ca, Al, Zn, As, [SO4], [PO4]). The iron oxide component was separated by repeated leaching in distilled water followed by centrifugal extraction. Analytical transmission electron microscope techniques (TEM, HRTEM, TEM tomography, SAED, EDS) were applied to investigate morphology, structure and chemical composition of the iron oxide/hydroxide phases. Two types of iron oxide/hydroxide were recognised, which differ in both morphology and chemical composition: a rounded (Fig. 1) and a needle-like one (Fig. 2). To characterise morphology we used TEM tomography. The rounded iron oxides are 100.200 nm plates, in their chemical composition the Fe (+Si,Al) : O atomic ratio is 1 : 3 and the As content is 2.8 wt%. The needle-like iron oxides are 50 nm long needles aggregated into 100.200 nm spheres. Their Fe (+Si,Al) : O atomic ratio is 1 : 2 and the As content is 2.5 wt%. We calculated pair-distribution functions (PDF) from electron diffraction patterns (SAED) to determine specific atomic distances for both iron oxide types.

MINERALOGICAL EXAMINATION OF HAZARDOUS WASTES

Szabó, B. & Weiszburg, T. G.



In Hungary, like in the whole European Union, there is an increasing demand for waste recycling in contrast to waste deposition. Parallel to that tendency, the application of natural resources (e.g. clay as pure geological medium) during the construction, running and rehabilitation of solid waste repositories is getting more and more limited. The present study aims to combine the above outlined two environment-sensitive industrial approaches by substituting the clean geological medium by properly treated solid hazardous wastes in the course of the rehabilitation of waste piles. In a first stage five different solid waste types, all of them classified as hazardous, were examined for their mineralogical and geological characteristics, including chemical and phase composition. In a second, currently still running stage these wastes have been treated in different ways in order to stabilize them adequately. X-ray powder diffraction, SEM+EDX and partial wet chemical analysis were performed on 1) fly ash of a communal incinerator; 2) sewage sludge residue from the cleaning of smelter gas; 3) a mud-consistency residue of gas cleaning in a former gas factory (“gas mud”); 4) cutting and milling waste of a metal processing company and 5) CaF2-containing mud waste from lighting industry. Four different treatments were applied to the fly ash (waste type 1) of the communal incinerator. The above mentioned analytical techniques were also used to characterise the treated samples of the fly ash. The treatment with a Na2SO4-dominant leachate, itself also a waste material, seemed to be the only one properly fixing the toxic components of the fly ash. When a limited amount (around 10 vol%) of cement was added to the fly ash + Na2SO4-dominant leachate mixture, the dissolution of toxic elements was already above the threshold limit values given by the environmental standards. Our results show that the treated fly ash, besides its proper chemical behaviour, is also of the engineering advantage that it behaves like concrete. In its original, fresh form it is plastic, it can fill up the voids and fissures of the deposited mixed solid wastes of the repository, while in a few weeks it hardens and limits largely the water circulation within the repository. The reduced amount of circulating water decreases the environmental risk of the rehabilitated repository. The treated fly ash can also be used for covering the filled-up repository, thus it is a good candidate for being a substitute of a suitable clean geological medium. At the sewage sludge (waste type 2) the high zinc content is the barrier of its direct metallurgical use. We found that part of the zinc in the waste, present as micrometer-sized zinc sulphide grains embedded in calcite, is easy to remove, however the other part, built in the spinel structure, needs further development of the separation techniques. The “gas mud” (waste type 3) is chemically and mineralogically too complex for a similar usage in rehabilitation, but further chemical processing tests may lead to techniques where a larger amount of the non-toxic metal content can be extracted and reused in metallurgy, while the total volume of the hazardous solid waste to be deposited will be largely reduced. Further studies for the application of the waste types in waste repository use are in progress.

There was a special white ware in Buda, the capital of the Hungarian Kingdom in the Middle Ages. It basically consisted of table ware (bottles) with thin walls, sometimes red painting but more often engraved decoration. According to HOLL (1963), the ‘Buda white ware’ appeared during the 13th century and spread over the middle and northern part of the kingdom. It was his suggestion that the manufacturing happened somewhere in the near-Buda rural pottery workshops (domestic industry). However, some contradictory evidence emerged during the later researches. This special pottery can also be found in pre-13th century contexts. In the archaeological assemblages of the northern parts of the Hungarian Kingdom (present Slovakia) it is interpreted as an imported product and there is no obvious raw material in the region of Buda for this kind of pottery. The aim of our research was to give preliminary archaeometric data about this special white ware by microscopic petrographic observations and basic mineralogical investigations (XRPD). Although in the first stage of the research it was possible to investigate only a limited number of ceramic finds, differences in raw material usage could be proved. The analyzed fragments came from archaeological sites of the 12th–14th centuries in different distances from Buda. According to the archaeological observations of Gál-Mlakár (2008), three types of the ‘Buda white ware’, namely ‘yellowish white’, ‘white’ and ‘greyish white’ can be macroscopically distinguished in the excavated assemblages from the eastern part of the kingdom. However, these types cannot be observed distinctly in the archaeological sites to the west. Investigating ceramic artefacts from some East Hungarian sites (Komlóska, Füzér, Sárospatak) we were able to distinguish differences in the mineralogical composition of the three archaeological types of ‘Buda white ware’. Although it was common in every type that very fine-grained, very plastic clay was used as the paste of pottery and it was tempered with sand derived from low-grade metamorphic and granitoid rocks, three different clay types could be identified as the paste. The ‘yellowish white’ type of ‘Buda ware’ which is pleochroic under the microscope has illite-smectite mixed layer silicate composition. The paste of the ‘white’ type of ‘Buda ware’ is characterised by iron-free illitic-smectitic clay, while that of the ‘greyish white’ type is illitic in composition. Results are less clear-cut for ceramic fragments from sites in the western part of the distribution area (Fels zsolca, Üll , Maglód, Vecsés, Gyál). They can partly be classified into these three material types but in some cases they look like objects or lower quality imitations made from almost the same raw clays. GÁL-MLAKÁR, V.

BIOMINERALS

Pósfai, M.

University of Pannonia, Veszprém, H-8200 Hungary


Why are our bones strong and tough, why are our teeth hard? How do mussels and snails build their shells? Why can bacteria and birds navigate in magnetic fields? The lecture attempts to give answers to these questions: in all cases a biological function, such as support, protection or orientation, is served by composites of organic materials and inorganic crystals – biominerals – that form inside the living organism (MANN, 2001). The sizes, shapes, compositions, structures and arrangements of the mineral grains in the organism are all tightly controlled by various biological mechanisms that affect crystal nucleation and growth (Fig. 1). The highly constrained properties of biominerals distinguish them from their inorganically-formed counterparts. The study of biominerals uses research techniques and knowledge from several disciplines, including mineralogy, biology, physics, materials science and geology. In this lecture, we will employ a cross-disciplinary perspective to broadly review the functions, formation mechanisms and properties of biominerals.

Figure 1. Two pairs of chains of magnetite (Fe3O4) nanocrystals in the cell of a magnetotactic bacterium. The white lines represent a map of the magnetic induction, as obtained from electron holography in a transmission electron microscope, while the colours show the direction of the magnetic induction according to the colour wheel shown in the lower left. The highly constrained sizes, shapes and orientations of the ferrimagnetic nanocrystals result in a uniform magnetization along the chains, enabling the cell to swim parallel to the Earth’s magnetic field. Figure adapted from SIMPSON et al. (2005).
