ABSTRACT: The study area that is
part of Tarom volcano-plutonic zone which host many hydrothermal base metal
deposits located in Zanjan, NW Iran. Understanding the tectonic events that can
cause mineralization and hydrothermal alteration are significant factor in
assessing the exploration potential of different structures. In this research,
hydrothermal alteration such as Iron oxide, argillic, phyllic, and propylitic
zones were determined by Spectral Angle Method (SAM) and also lineaments
identified by high pass filters and hill-shade DEM techniques on Advanced Space
borne Thermal Emission and Reflection Radiometer (ASTER) data. Field studies
revealed most alteration and mineralization occurred in NE-SW fractures and
control mineralization.
