Abstract: Khatunabad area is situated geologically in Urmieh-
Dokhtar magmatic belt in NW of Iran. In this research, studied area
has been investigated in order to recognize the potential copper and
molybdenum-bearing target areas. The survey layers include the
lithologic units, alteration, geochemical result, tectonics and copper
and molybdenum occurrence. As an accurate decision can have a
considerable effect on exploration plans, so in this efforts have been
made to make use of new combination method. For this purpose, the
analytical hierarchy process was used and revealed highly potential
copper and molybdenum mineralization areas. Based on achieved
results, geological perspective in north of studied area is appropriate
for advance stage, especially for subsurface exploration in future.
Abstract: The Mahin area is a part of Tarom- Hashtjin zone that
located in west of Qazvin province in northwest of Iran. Many copper
and base metals ore deposits are hosted by this zone. High potential
localities identification in this area is very necessary. The objective of
this research, is finding hydrothermal alteration zones by remote
sensing methods and best processing technique of Advanced
Spaceborne Thermal Emission and Reflection Radiometer (ASTER)
data. Different methods such as band ratio, Principal Component
Analysis (PCA), Minimum Noise Fraction (MNF) and Least Square
Fit (LS-Fit) were used for mapping hydrothermal alteration zones.
