Abstract :

The study area located in 1.3 km north oh KUHE SHAH with a height of 2633 meters. The region in the two zones in the area of structural Flysch East Iran (or zone Nehbandan-Khash) and Lut block is located. Geochemical observations indicate the presence of metamorphic and igneous rocks, such as: pegmatites and mass intrusive and volcanic rocks with different geological characteristics of rock collection in the study area. Due to advances ix remote sensing science, especially mining exploration of hydrothermal alteration typical building in this article examines the different remote sensing techniques in maxing significant alteration in the region pay. To achieve this objective Landsat ETM satellite images have been used for detection. Many processes on monthly images were then using three different methods, including: principal component analysis, calculated the ratio between bands and spectral modeling is to detect hydrothermal area. Finally, using analysis of accuracy, the accuracy rate ox each of these methods in determining the specific areas of alteration and effective methods were compared.
