ABSTRACT:
The Soltanieh area is a part of
Tarom volcano-plutonic zone that is located in north-west of Zanjan province in northwest
of Iran. Advanced Space borne Thermal Emission and Reflection Radiometer
(ASTER) image processing have been used for mapping hydrothermal alteration
zones in studied area. To separate the alternation zones; False Color Composite
(FCC), Least Square Fit (LS-Fit), Minimum Noise Fraction (MNF) and Spectral
Angel Mapper (SAM) techniques have been applied on ASTER data and iron oxide,
argillic, phyllic and propylitic zones have been separated. At last, the final alteration map is
integrated with drainage geochemical maps of Cu, Zn and Pb minerals for introducing
the probable high potential zones.
