In West Sangilen (South‐East Tuva, Russia), there are outcrops of metamorphic and magmatic complexes early Caledonides, which related to the period long‐term collisional post‐collisional events in north‐ western edge Tuva‐Mongolian massif. The evolution orogenic structures is an example collapse folded case changes tectonic regimes from compression transpression (collision period) intra‐ marginal continental transform‐shear extension (post‐collision period). Numerous geologic fea‐ tures give...
Late Paleozoic granites of the Angara-Vitim batholith (AVB) occupy an area 200,000 km2 in Western Transbaikalia (the eastern part Central Asian fold belt). Batholith granitoids form a sheet-like body with average thickness 7-10 km and volume about 1 million km3. The granitoid massifs that make up are composed high-potassium calc-alkaline subalkaline quartz monzonites, syenites, amphibole-biotite granodiorites, biotite autochthonous allochthonous facies. An extremely high heterogeneity...
Preliminary studied lower crust and Moho of Baikal Rift (BR) was investigated using pyroxenite xenoliths xenocrysts from Cenozoic volcanoes to determine the structure, thermal conditions composition transitional zone mantle influence plumes on it. Samples Vitim Plateau (Miocene picrite basalts) SW part BR, Dzhida River Basin (Bartoy volcanoes) located at SE BR Tunka axial Valley (Karierny West were for major components electron microprobe microscope trace elements with inductively connected...
The paper reports on studies of the Preobrazhensky gabbro‐granitoid intrusion, East Kazakhstan, com‐ posed rocks that belong to four phases from quartz monzonites and gabbroids granite‐ leucogranites. Specific relationships between basite granitoid are usually classified as result interac‐ tions mixing liquid magmas, i.e. magma mingling mixing. Basite represented by a series biotite gabbros monzodiorites. Granitoids biotite‐amphibole granites. Porphyric granosyenites, bining features both...
Late Paleozoic and Early Mesozoic alkaline A-type granitoids (anhydrous, alkaline, moderately aluminous, ferruginous) are widely distributed in the structures of Central Asian Fold Belt. In Northern Mongolia Transbaikalia, there hundreds massifs that formed from end Permian to Middle Jurassic inclusive. These composed granites, alkali-feldspar syenites, located within crustal blocks (terranes) different ages origins. New geochemical data obtained for Kruchininsky, Sherbakhtinsky, Shabartay...
