【正文】 ce yushu Tibetan autonomous prefecture song ma ma lai county township north, tectonic position in BaYanKaLa indosinian orogenic belt on the north, north by a cloth green south slope fracture adjacent to nima o qing suture of the large gold deposit of gold mineralization type orogenic type gold deposits, we through large area 1: after 50000 mineral geological investigation and study that large field with western northeast sichuan village gold, gold gold northwest guangxi, such as analogy, the gold mineralization types for the microgranular disseminated type gold deposit. A large 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
