Structural Evidence And 3D Modeling of Kervian Gold Deposit- SW Saqqez- Kordestan Province- Iran

Kervian mining area is the first area for genesis of shear zone-related gold mineralization in Iran. The aim of this study is completion of structural geology aspect, analysis of 3D model and finally the determination of structural controls in mineralization. Based on the structural evidence, three episode of deformation were recognized in the Kervian shear zone. Between this stages, Second stage(D2) have been caused development of Milonitic foliation and the most intense of structural deformation in study area. The dip and strike of faults was determined based on Stereoprojection and Roze diagram. These faults were classified in two goups. First group, are thrust faults that have NE-SW strike and 40-60° dips to NW. Second groups of faults, are vertical faults that indicate strike-slip right lateral motions. Then, 3D model of Kervian deposit were drawn with Datamine software. A comparison of structural evidence to 3D modeling indicate that mineralization current at depths of 125-200(m) and perfectly isoclinal with geology structures in Kervian. These evidences indicate that main factor of mineralization is controlled by structural factorʹs in Kervian mining area.
