Remote Sensing And GIS Application In Mineral , Oil , Ground Water MappingMineral by me

  1. 1. Remote Sensing AndGIS Application InMineral , Oil , GroundWater MappingBySwetha A
  2. 2. Introduction• Mineral• Oil• Ground Water
  3. 3. Minerals ACCOMMODATION ZONES Deep-crustal breaks that often become syntectonic volcaniccenters because they localize the magmatic material, thusbecoming an elongated volcanic and plutonic center that intrudesexisting fault zones and provides the thermodynamic energy todrive mineralized fluids Increase in brecciation and the number of faults with a netdecrease in the average fault slip within the accommodation zone Localized compressional stress regime forms anticlinalculminations located structurally up-dip from the normal faults itseparates or "accommodates" on either side
  4. 4. Diagrammatic representation of opposite polarity tilt patterns in extensionalterrenes as separated by a strike-slip or transfer fault (A) or an accommodation zone(B).
  5. 5. Landsat TM 741 color composite image of the southern Colorado Riverillustrating extensional faults and the newly interpreted accommodation zone.
  6. 6. Saline Valley,California —ASTERvisible and near infraredbands 3, 2, and 1 in red,green, and blue (RGB)short wavelengthinfrared bands 4, 6,and 8 as RGBthermal infraredbands 13, 12 and10 as RGB
  7. 7. Valuable data for the planning andexploration program• The advantage of creating large scale area maps which allows them toexamine in single scenes or in mosaics the geological portrayal of Earthon a regional basis.• The ability to analyze multispectral bands quantitatively in terms ofnumbers permits them to apply special image processing techniques todiscern 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) orcombining these with topographic elevation data (DEMs) and with otherkinds of information bases (e.g., thematic maps; geophysicalmeasurements and chemical sampling surveys) enables views of existingor planning of proposed mines.• Mapping subregional surface geology.• Creating field exploration maps with detailed views of access roads.

  13. 13. The Morenci open-pit copper mine in southeast Arizona is North Americasleading producer of copper.
  14. 14. Oil
  15. 15. subsurface oilwell
  16. 16. Exploration• Oil and gas exploration activities for large areasrequire airborne magnetic or ground gravity surveysto facilitate detailed geological interpretations forsubsurface features.• By utilizing orthorectified high resolution satelliteimage data and Digital Terrain Models (DTMs)generated from Stereo Satellite or Airborne sensors,SIC delivers detailed computer visualizationenvironments for desktop programs such as ArcGIS9.x with Spatial Analyst and 3D Analyst withDSM/DEM posting intervals from 3m to 90m.
