Abstract

In the gabbro intrusions of AP batholith rocks the manifestations of ore mineralization of magnetite, ilmenite and sulphides in connection with intramagmatic dikes and more late gabbro-pegmatites were defined. The elevated concentrations of V, Co, Cu were estimated. А significantly higher content of Cu, U, Th, Sc and REE is observed in gabbros of intramagmatic postintrusion dikes. The Co content in pyrite reaches 3,5 %. The ore mineralization of pyrite, chalcopyrite and magnetite in the granite intrusions is associated with quartz veins of post-tectonic hydrothermal stage and with epigenetic processes in the tectonic faults. The impurities of Ag and As in sulfides from this zones were detected.
