Considering the importance of mineral development as a goal of the Third Development Program of Iran, GSI defined 20 exploration zones according the world standards. Ahar-Arasbaran is one of these 20 zones. In this project with compilation and modeling of geological, geochemical, geophysical, satellite, and mineral data, several potential areas were identified that controlled during 30 days filed visit, sampling and analysis.
The Ahar-Arasbaran zone includes 10 sheets (1:100000) of Lahrud, Meshkinshahr, Kaleibar, Ahar, Varzaghan, Khajeh, Siyahrud, Tabriz, Jolfa, and Marand. Systematic regional exploration applies geological, geochemical, satellite, geophysical, and mineral data to identify favorable mineralized zones. After compilation and modeling, each zone is modeled based on the known genesis models that transformed the data to useful information including structure, origin, host rock, mineralization process and so on. These works are completed by field visit and checking.
Considering the geological setting of the Ahar-Arasbaran zone in northwest of Iran, the aim of project was the exploration of gold and porphyry type copper resources. Field visits were done in two steps totally reach to 30 days.
In modeling of the region, in addition to known mines and deposits of Mazraeh, Gowdal, Anjerd, Sungun, Nabijan, Noqduz, Sharafabad, Hizejan and Qara Chillar, several new favorable zones were identified. This report describes the result of modeling and visits from these new identified zones and not considers the previously known deposits and mines.
