【正文】 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。擠壓作用導(dǎo)致巖 層發(fā)生褶皺變形、巖石破碎和位移的過程中，有大量構(gòu)造動能轉(zhuǎn)化為熱能，運動巖塊之間 的摩擦熱甚至可以達(dá)到使巖石熔化的程度。大場金礦的成礦物質(zhì)來源于圍巖，亦就是作為 2 含金地質(zhì)建造的濁積巖。粉砂巖層中發(fā)育遠(yuǎn)洋薄殼特點的雙殼化石 (Halobia)和遺跡化石高原漫游跡 (( Plnolitesm ontanus)，具典型深水濁流相特點。大場礦區(qū)含絹云母石英脈 Ar Ar法測得成礦年齡為 218. 6士 3. 2Ma，屬印支晚期 。 金礦體多呈 NW一 SE向等間距分布的特征，截止 2020年已控制金礦體 33條，礦體延 伸長度從 160一 2700m不等，礦體厚度 ~,沿礦體傾向控制斜深 187m。金礦體在平面上嚴(yán)格受斷裂構(gòu)造破碎帶控制，因而容礦巖石普遍具不同程度的破碎變形，直至部分成為碎裂巖。主要蝕變有硅化、絹云母化、硫化物化，局部有高嶺土化、碳酸巖化。大場金礦床主要有兩種流體 :其一是 CO2一 H20體系流體，其二是 NaCIH20體系的流體。濁積巖建造、區(qū)域性地?zé)岙惓：团涮讛嗔严到y(tǒng)是成礦最重要的條件。粉砂巖 ，變化系數(shù) 400%。微細(xì)粒浸染型金礦的成礦，需要一 定的熱動力條件，以驅(qū)動礦源層中的成
