Spectral geology is the method used to identify, classify and map minerals and is the fundamental technique for the interpretation of remotley sensed imagery and more specifically hyperspectral (HyMap) data. Hyperspectral (HyMap) imagery can accurately map areas that are spectrally unique at the surface to produce very detailed and comprehensive mineral maps.
These mineral maps can include;
- Indicators of primary rock type
- Signatures of alteration in mineralised environments
- Indicators of weathering regimes and processes
- Indicators of mineral chemistry & formation temperature
Examples of HyMap mineral mapping are presented in the following images;
