The studied area—Kermejegan—is located in the south of Qom Province, Iran. In this paper, geology map, ASTER
and ETM7+ satellite images were used and after processing these images with
Geomatica and ENVI softwares, iron potential zones were compared with the iron mine
position in the south of the area and 2 dominate indexs around. Finally remote
sensing, faults and geological data layers were integrated in GIS and hopeful
zones were introduced for continuing the exploration processes.
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.
