Determination of Hydrothermal Alteration Areas by Aster Satellite Images: Ağmaşat Plato- Zara (Sivas) / Turkey Sample
Abstract
Determination of hydrothermal alteration areas is one of the first stage
methodes used in mineral exploration studies, particularly of porphyry type
mineralizations. These studies were only possible by field investigations in
the past, but now, they can be easily detected with images from satellites, in
accordance with the developing technology. In this study, contacts between
geological units and the border of the hydrothermal alteration zones were
determined with SWIR images of ASTER in Ağmaşat Plato, located in the north of
Zara district of Sivas province. Decorrelation stretching and principal
component analysis were carried out on the SWIR images. The obtained results
highly coincide with the geological map which was prepared during the field
studies. These results will lead to the discovery of new potential fields.
