Kordonnoe scheelite-sulfide skarn deposit: Criteria of relations to igneous rocks differing in age
Abstract
The results of the study of granitoids from the Kordonnoe scheelite-sulfide skarn deposit in the Malinovka ore field are discussed in this paper. Igneous rocks in the studied area are represented by granites differing in age, which are distinguished in petrography, chemical composition, and thermobarogeochemical characteristics. The genetic relationships of scheelite mineralization to granitoids of the Tatibi Complex are supported by similar REE patterns of granitic rocks and scheelite from ore veinlets and by comparison of thermobarogeochemical characteristics of the ore-bearing solutions and the fluids that accompanied emplacement of granites. Comprehensive investigations have shown that the deposit is multistage and polygenetic. Two stages in the formation of igneous rocks and mineralization are recognized in the evolution of the oremagmatic system.
