| 摘 要： | 湖南桂东县青石岭钨多金属矿是近年来南岭成矿带上国土资源大调查发现的具较大找矿潜力的地区。在前人研究的基础上,应用辉钼矿铼-锇同位素法对产于诸广山复式花岗岩体中的破碎带蚀变岩型钨多金属矿进行精确定年。结果表明,破碎带蚀变岩型钨多金属矿辉钼矿铼-锇等时线年龄为(147.6±6.8)Ma;钨多金属矿与燕山早期花岗岩侵入活动有关,是南岭中生代大规模成岩成矿作用高峰期的产物。 |

| Abstract: | The Qingshiling tungsten-polymetallic deposit field in Hunan province is a new discovered metallogenic region with great potential of mineral prospecion. Based on the previous research progress in this region,Re-Os isotopic age of molybdenite from fracture zone-alterated rock type of tungsten-polymetallic deposit in Zhuguangshan complex granite rock-body. The isochron age of (147.6±6.8) Ma was obtained,which suggests its mineralization is related to the Early Yanshanian granite intrusive activities. |
| Keywords: | the Qingshiling tungsten-polymetallic deposit molybdenite Re-Os isotopic dating geological characteristics East Hunan |
