| 中文摘要:盘古山钨矿床是南岭地区著名的大型钨矿床。通过氢、氧、硫和硅同位素地球化学特征的研究,对盘古山钨矿床的成矿流体和成矿物质来源进行了探讨。研究结果显示:成矿流体δD值介于-121.7‰~-80.6‰,δ18O值为2.97‰~6.47‰,硫化物δ34S值集中分布于-2.3‰~1.3‰,石英脉的石英δ30Si平均值为-0.44‰;花岗岩的石英δ30Si平均值为-0.53‰;砂岩的石英δ30Si平均值为0.2‰。研究结果表明:盘古山钨矿床的成矿流体、成矿物质以及硅质均主要来源于花岗岩浆,少部分成矿流体来自大气降水,少部分硅质来自砂岩地层。 |

| Abstract:Southern Jiangxi Province is well known as the world leading tungsten producer. The Pangushan tungsten deposit in this area is a representative large-sized tungsten polymetallic deposit closely associated with granite. In this study, the authors presented its hydrogen, oxygen, silicon and sulfur isotopic data and investigated the origin of its ore-forming fluid. The results show that δD values of the fluid from quartz vary from -121.7‰ to -80.6‰, δ18O values range from 2.97‰ to 6.47‰, and δ34S values of sulfide is in the range of-2.3‰~1.3‰. The average δ30Si value of quartz from mineralized quartz-vein, granite and sandstone is -0.44‰, -0.53‰ and 0.2‰, respectively. The results indicate that the ore-forming water, material and silicon was derived mainly from the granitic magma, with the addition of a little water and silicon from meteoric water and sandstone respectively. |
