The Soltanieh area is a part of Tarom volcano-plutonic zone that is located in north-west of Zanjan province in north-west 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
