Remote sensing processes for detecting geological tectonic structures and alteration zones in the exploration zone of Miyaneh city (northwest of Iran)

This study aimed to investigate the mineralization potential of such metals as copper, gold and molybdenum at the Miyaneh's zone level (focusing on the western and eastern-northeastern areas). For this purpose, the proposed approach was to use direct geological studies and to take samples on the mineralization of these metals. Indirect data (telemetry) were used to discuss mineralization potentiality. In this connection, satellite and telemetry data were used for mineralization and alteration in the study area as the results were classified. At this stage, such software as Envi, Arc GIS and Image analyzer were used. The findings revealed that the Miyaneh's eastern zone was not found to generate any metal potential. In the western part of the said zone, the situation of metal mineralization is different, because intrusive, semi-deep and existing igneous rocks are widely seen in this area which are often exposed to the alteration phenomenon. These conditions have led to the metal mineralization in some western zones of the city. The most important mineralization processes include the presence of gold mineralization in siliceous veinlet, the presence of molybdenum mineralization in the form of veinlets and the presence of iron mineralization in the form of goethite and hematite.
