Determination of Hydrothermal Alteration Areas by Aster Satellite Images: Ağmaşat Plato- Zara (Sivas) / Turkey Sample
Journal Title: Cumhuriyet Science journal - Year 2017, Vol 38, Issue 3
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.
