Aghyokhush group and Mereh deposits are situated in the Dashkesan district of Azerbaijan, within a Cau-casian segment of the Tethyan metallogenic belt, one of the world's major metallic provinces, that con-sists of many sectors. The geodynamic evolution of the Caucasian segment of the Tethys metallogenic belt was observed with the subduction and collision of Arabia and Gondwana-derived microplates with the Eurasia plate. The geological structure of the Chovdar ore area where is Aghyokhush group and Mereh deposits are located made of complex Middle and Upper Jurassic magmatic, metamorphic, and sedimentary rocks. The mineral assemblages and alteration zones observed in the Aghyokhush group and Mereh ore deposits are considered indicators for explaining the formation mechanism of mineraliza-tion.
