【正文】 ge gold deposit geological background Big game gold deposit in north BaYanKaLa indosinian yanshanian gold, antimony mineralization belt, the gold mine of fu seam for Triassic ba yan kara mountains SLATE clip sandstone group, is a set of typical turbidite, ore rock mainly for dark grey mud calcium feldspar sandstone SLATE, speckled SLATE gray. Gold ore body in the plane strictly controlled by the fault fracture zone, and therefore with different degree of broken ore rock mon deformation, until the part be cataclastic rock. Fracture structure more along the anticline axis. Mining area development of hydrothermal alteration, its size and strength is determined by structural fracture zone scale, nature and rock the petent. Major alterations are silicification, sericitization and sulfide materialized, local kaolin, lithification carbonate. Pyritization, poison placer, stibnite, sericitization, silicification and gold mineralization, the most closely, the ore body center outward silicide, vulcanization materialized, sericitization, lithification carbonate, kaolin. Ore minerals are mainlypyrite and arsenopyrite, gangue mineral. Gold ore body is in a SE to NW spacing distribution characteristics, such as control by 2020 has 33 gold orebodies, the ore body stretch length ranging from 160 a 160 m, ore body thickness ~ m, 187 m along the deep ore body tilted control. Gold ore grade of up to 110 g/t, lowest g/t, general 2 ~ 9 g/t, the average 5. 76 g/t, through to the mining area of 24 ore resource estimation, a total of 333 + 334 gold resources in 334. The 4 tons, up to large scale. Pyrite ore deposits in the surrounding rock and ore of single mineral of the delta 34 s value between a % 0 %, the average 4. 97% 0, numerical range is small, shows that formation of sulfur source. Big game there are two main types of gold deposits in the fluid: one is the CO2 fluid H20 system, secondly, NaCI H20 system of fluid. The former was formed in 236 ℃ , 4 315 ℃ , low salinity ( WTD/mNaCI), rich CO2 and CH4 and (or) a small amount of N2 ponents concentration between a ℃ to ℃ , slightly lower than the triple point temperature of pure CO2。 208 pb / 204 , average of 38, 2918, is a typical anomalous lead. In (1988) such as Zarlman lead isotope structure model, the above data are lies between the mantle and the evolution of orogenic belt line and side concentration distribution near the line of evolution of orogenic belt. Large field mining area with sericite quartz vein Ar Ar method measured metallogenic age of 218. 6 and 3. 2 ma, belong t
