Favourable tectonic setting and fracture network environment for the formation of the giant Kadjaran porphyry Cu-Mo deposit in Armenia, Lesser Caucasus

摘要

The giant Kadjaran porphyry Cu-Mo deposit is situated in the southernmost Lesser Caucasus in Armenia and belongs to the Central segment of the Tethyan metallogenic belt. Cenozoic evolution of this segment was dominated by oblique convergence and final collision of the Arabian plate with the Eurasian margin. The composite Meghri-Ordubad pluton of the southernmost Lesser Caucasus was emplaced during this evolution. It hosts major porphyry Cu-Mo and epither-mal Au deposits and prospects, including the giant Oli-gocene Kadjaran porphyry Cu-Mo deposit.
