Behavior of alkali element uranosilicates and uranogermanates in saturated aqueous solutions

Phase transformations of Bi, Sb, Se, Te and U in the oxidation model of wolframite rocks of the Sherlovaya Gora deposit (Eastern Transbaikalia)

“…On the basis of the large tin-polymetallic deposit Sopka Bolshaya, discovered in 1930, the largest tin mining centre in the USSR, Sherlovogorsky, was built and operated until 1993 MPP. 1) Quaternary sediments; 2) Lower Cretaceous sediments, Turga Tier: sandstones, mudstones, conglomerates; 3) Lower Carboniferous: Shale-sandstone strata with interbeds of effusive rocks and less frequently limestone with fauna of Turne-Visean age; 4) porphyry granite and porphyritic granite (Mz); 5) uniformly medium-grained granite; 6) eruptive breccia of quartz porphyries of phase II (Mz); 7) subintrusive quartz porphyries of phase I; 8) diorite porphyrites and porphyrites, less frequently gabbro-diorite-porphyrites, gabbrodiorites and diorites (Pz); 9) fluid porphyrites, their tuffs and tuffobreccias (Pz), 10) serpentinites (on ultrabasites); 11) Paleozoic plagiogranites and granites; 12) discontinuities; 13) zone of buckling, stratification and crushing; 14) supposed underground continuation of the Sherlovogorsk granite massif; 15) greisen bodies; 16) areas of greisenisation in granite host rocks; 17) zone of contact metamorphism; 18) quartz-tourmaline veins with tin; 19) zones of tourmalinisation; 20) ore areas and their numbers: 1 -Sherlovogorsky greisentungsten, 2 -Sopka Bolshaya, 3 -Quartz-tourmaline spur, 4 -Aplite spur, 5 -North-Eastern, 6 -Eastern, 7 -head of Zavodskoy Pad, 8 -Vysokiy; 21-24 -mineralisation zones: 21wolframite-greisen in granites; 22 -quartz-feldspar-wolframite-cassiterite; 23 -tourmalinesulphide-cassiterite; 24 -sphalerite-galenite with weak sulphide-cassiterite mineralisation.…”
