垅西金矿是东天山地区较为典型的石英脉型金矿床 ,文章对该矿床进行了流体包裹体的温度测定、气液相成分分析、稀土元素分析和氢氧同位素分析。研究结果表明 ,垅西金矿的成矿温度为 2 2 2～ 313℃ ,成矿深度为 2～ 3.2km ,属中成中温热液矿床 ;流体包裹体中H2 O和CO2 为主要气相成分 ,Na+ 、K+ 和Cl-为主要液相成分 ;成矿流体主要来自岩浆水 ,晚期混入少量大气降水 ;成矿金属物质主要来自下石炭统企鹅山群中基性火山岩
The Xixi gold deposit is a typical quartz vein type gold deposit in the East Tianshan area. The temperature of the fluid inclusions, gas-liquid composition analysis, rare earth element analysis and hydrogen and oxygen isotope analysis of this deposit have been studied. The results show that the metallogenic temperature of the 垅 Xixi gold deposit is between 22-22 ℃ and the ore-forming depth is 2 ~ 3.2km, which belongs to the midmiddle-mesothermal hydrothermal deposit. The contents of H 2 O and CO 2 in the fluid inclusions are the main gas phase components , Na +, K + and Cl- are the main liquid components. The ore-forming fluid is mainly from magmatic water and a small amount of atmospheric precipitation is mixed in the late stage. The metallogenic materials mainly come from the basement volcanic rocks
