【摘要】 祁雨沟金矿床产于燕山期热液角砾岩筒内。通过对 4号角砾岩体胶结物和石英 -碳酸盐脉内流体包裹体研究表明 ,其中的包裹体类型非常复杂 ,有气体包裹体、气液包裹体、液体包裹体、含子矿物高盐包裹体和含 CO2 包裹体五种类型。成矿的初始热液为高温高盐流体 ,它们来源于燕山期花岗岩浆热液。由于角砾岩体的隐爆、流体减压沸腾及古大气水的混入 ,热液中的金被沉淀成矿 ,形成胶结物型和脉型金矿化。金矿的开始成矿于温度较高 (310～ 390℃ )的中阶段 ,并可能延续至中温(2 0 0～ 2 90℃ )的成矿晚阶段早期更多还原

【Abstract】 Qiyugou gold deposit is located in Yanshanian hydrothermal breccia related pipe. Fluid inclusion types in breccia cement and quartz carbonate veins in No.4 breccia pipe are complex. Five types inclusions like vapor, vapor aqueous, aqueous, high saline halite bearing and CO 2 bearing inclusions are found. Initial ore forming fluids are high temperature and high saline which were related with Yanshanian granitic magmatism. Cryptical blasting, fluid boiling and meteoric water mixing are reasons of gold deposition in the deposit, forming cement type and vein type mineralisation. Temperature of gold mineralisation came from higher temperature (310~390℃) to middle temperature (200~290℃) early late stage of mineralisation.更多还原
