ASTER Alteration Mapping Package

Alteration mineral mapping is a powerful resource when looking for certain types of deposits, such as epithermal and porphyry deposits. By examining the distribution of alteration minerals, exploration geologists can select better targets for advanced exploration.

At the regional scale, the ASTER Alteration Mapping Package is a suitable tool for choosing targets.
