5. Mineralogy laboratory

X-Ray Diffraction (XRD) is a widely used investigative technique in mineralogy. The qualitative and quantitative mineral composition of a sample is estimated through this technique. Polytypes, in particular, can be identified and the crystallinity of mineral species can be assessed. It is an extremely powerful tool used for the examination of clay materials.

The Scanning Electron Microscope (SEM) with a microanalysis system (Energy Dispersive Spectroscope — EDS) attached to it is utilised for imaging the X-ray microanalysis of rocks, minerals and industrial materials.

Scanning electron microscopy is widely utilised in applied mineralogy investigations and increasingly more in environmental studies where the characterisation of microscopic particulate matter is required. In conjunction with other analytical techniques, SEM is a strong tool for solving various industrial problems associated with soil/water contamination, process control, product failure corrosion and product development. It provides the researcher with topographic imaging of the material surface with qualitative and quantitative compositional information of the matrix to assist in scientific solutions deriving and enhancing the quality of the scientific research product. The laboratory has a newly acquired Field Emission Gun Scanning Electron Microscope.

6. Petrography laboratory

Petrology explores the origin, history and structure of igneous, metamorphic and sedimentary rocks, as well as soils. Petrographic techniques offered by the laboratory include:

• Basic and detailed descriptions of rocks and modal and strain analyses.

• Analyses for the alkali-aggregate reaction potential of rocks used in construction.

• Petrographic sample preparation services are available and include the cutting of rock samples to make standard and large-format polished thin sections, the production of double-polished wafers and the polishing of rock specimens and stubs.

7. Rock physical properties laboratory

The facility focusses on the measurement of physical rock

properties directly related to geophysical methods and boasts a well-equipped section for the measurement of palaeomagnetic and physical properties. The section is capable of performing measurements of the following properties:

• Magnetic susceptibility (mass and volume)• Anisotropy of magnetic susceptibility (AMS) • Normal remanent magnetisation (NRM) [direction and

intensity]• Thermomagnetic analysis • Magnetic remanence and Königsberger ratio• Bulk density (wet and dry)• Electrical resistivity (time domain and frequency domain)• Induced polarisation
