【文章內(nèi)容簡介】 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。 The latter39。s uniform temperature has two peaks: one is 232 ℃ , 275 ℃ and salinity a 9. 47 WTD/mNaCI, 2 it is 149 ℃ , 229 ℃ , salinity of a WTD/m NaCI. Immiscible function of fluid occurred in 236 ℃ 236 ℃ , the fluid does not mix solution of CO2 H20 fluid was isolated and NaCl H20 fluid is the main oreforming fluid of gold. Large field mining area 4 pieces of pyrite samples of 206 pb / 204 pb, ratio of to , with a mean of 。 207 pb / 204 pb, , with a mean of 。 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 to the late indosinian。 Contain pyrite, galena, quartz vein of the peacock petrochemical Pb a Pb method measured metallogenic age of 187 ma, belong to the early yanshan, visible its metallogenic epoch is the early stage of yanshan movement in the late indosinian orogeny and area. The above information shows that big gold mine of oreforming elements, sulfur and gangue ponents mainly es from stratum, the oreforming solution for atmospheric precipitation formation of deep groundwater. Turbidite fracture system construction, regional geothermal anomaly and matching is the most important metallogenic conditions. Two metallogenic conditions turbidite built for large formation of gold deposit provides a source of oreforming materials. Big gold deposit mainly occurs in the Triass
