Introduction

• Mineral

• Oil

• Ground Water

Minerals ACCOMMODATION ZONES

Deep-crustal breaks that often become syntectonic volcanic centers because they localize the magmatic material, thus becoming an elongated volcanic and plutonic center that intrudes existing fault zones and provides the thermodynamic energy to drive mineralized fluids

Increase in brecciation and the number of faults with a net decrease in the average fault slip within the accommodation zone

Localized compressional stress regime forms anticlinal culminations located structurally up-dip from the normal faults it

separates or "accommodates" on either side

Valuable data for the planning and exploration program

• The advantage of creating large scale area maps which allows them to examine in single scenes or in mosaics the geological portrayal of Earth on a regional basis.

• The ability to analyze multispectral bands quantitatively in terms of numbers permits them to apply special image processing techniques to discern and enhance certain compositional properties of Earth materials.

• The capability of merging different types of remote sensing products (e.g., reflectance images with radar or with thermal imagery) or combining these with topographic elevation data (DEMs) and with other kinds of information bases (e.g., thematic maps; geophysical measurements and chemical sampling surveys) enables views of existing or planning of proposed mines.

• Mapping subregional surface geology.

• Creating field exploration maps with detailed views of access roads.

Exploration

• Oil and gas exploration activities for large areas require airborne magnetic or ground gravity surveys to facilitate detailed geological interpretations for subsurface features.

• By utilizing orthorectified high resolution satellite image data and Digital Terrain Models (DTMs) generated from Stereo Satellite or Airborne sensors, SIC delivers detailed computer visualization environments for desktop programs such as ArcGIS 9.x with Spatial Analyst and 3D Analyst with DSM/DEM posting intervals from 3m to 90m.
