SHOSHONITIC GRANITOIDS OF TIGIREKSKII MASSIVE OF ALTAI: GEOCHEMISTRY, PETROLOGY AND ORE MINERALIZATION
The geological, geochemical and petrological data lead on shoshonitic graniroids of Tigirekskii massive of Altai. 5 phases detached in composition of massive: 1 - gabbro; 2 - diorites, monzodiorites; 3 - sienites, granodiorites, granosienites; 4 - granites, moderate-alkalic granites; 5 - leicogranites and moderate-alkaline leicogranites with fl uorites. Rock types of massive refered to normal calc-alkalic and shoshonitic petrogenetic sieries. Sienites and monzodiorites weighed to banakites on composition. Differentiation of deep spot melting and fractionation of rare earth elements in processes of forming massive that it was refl ected on ratio in rocks of elements groups LILE and HFSE with considerable depletation of last. Change of type tetrad effect fractionation of rare earth elements happened in rocks that it is link with different of saturation of melts by fl uids and volatile components. Deposits and manifestations of iron, tungsten, molibdenium, berillium, aquamarine, quartz cristal, rauhtopaz connected with massive.
