COMPLEX REMOTE SENSING TECHNIQUE (CRS)

is an up-to-date technique of mineral exploration where the latest state–of-the-art achievements in earth remote sensing and information processing technologies are used together with an integrated analysis of the results of all types of geological, geochemical and geophysical works.

 
SCOPE OF APPLICATION

The CRS technique is designed for detectionsatellite of mineral deposits indications on high-resolution multispectral satellite images. Such indications are unique for each specific useful mineral. Therefore the technique is adopted by “OZGEO” specialists for identification of the most promising areas where necessary minerals can be deposited.
Yet at the forecast-reconnaissance stage of geological exploration the use of CRS technique helps to significantly reduce the volumes of expensive ground exploration operations including drilling.

  1. Detection of spectral anomalies induced by ore bodies in infra-red band.
  2. Tectonic structure update based on the analysis of thermal field (far infra-red band).
  3. Expert identification of different rock types basing on the analyses of visible spectral bands.
  4. Comparison of thermal field and visible band analyses results for compilation of a structural geological map with the use of various geological-geophysical information.
  5. Results of the analysis reflected on the regional scheme of promising objects location (anomalies associated with the tectonic belt are marked by green color, those associated with basement protrusions - by violet color).
  6. Detailed analysis for planning future geological exploration activity.
