Malkinsky granite-leukogranite plutonic complex (North Caucasus)

Granitoids of the Malkinsky complex are exposed in the Karachay-Cherkessian horst-anticlinorium fold structure of the Greater Caucasus and penetrated by wells in the Central Ciscaucasia. Separate arrays and their relationships with host rocks are described, their petrographic and petrochemical compositions are given. Based on the results of the studies carried out, it was concluded that the rocks of the complex occupy an intermediate position between the I- and S-types of granites. The absolute age of the rocks of the complex, determined from zircons, ranges from 300 to 325 Ma, and taking into account geological data, the granitoids of the complex are assigned to the Middle Carboniferous.
