Abstract
The petrology and ore potential of the Talazhin Massif located in northwestern East Sayan are studied. The internal structure of the intrusion, the petrographic composition of its rocks, and their metallogenic, petrostructural, and petrogeochemical features are considered. The probable temperature and chemical composition of the parental magma of the pluton were computed using the KOMAGMAT-3.52 program on the modeling of equilibrium crystallization. The obtained data indicate that the Talazhin Massif is a rhythmically layered plagiodunite-troctolite- anorthosite-gabbro intrusion formed from low-Ti high-alumina olivine-basalt melt. It is promising for Cu-Ni-PGE mineralization.
