| 摘 要： | 老君山地区是滇东南多金属成矿带的重要组成部分,但对该区典型矿床精确的成矿时代和构造背景的研究较少.文章选择与锡石密切共生的金云母及与钨矿共生的辉钼矿为研究对象,分别运用40Ar-39Ar阶段加热和Re-Os同位素定年方法,对新寨锡矿床中的金云母及南秧田钨矿床中的辉钼矿进行了成矿时代的研究,获得了金云母的40Ar-39A...

| Abstract: | The Laojunshan area is an important part of the southeastern Yunnan polymetallic belt;nevertheless,the timing and tectonic setting of the typical deposits in this area were poorly constrained.In this paper,the authors present new 40Ar-39Ar dating of phlogopite closely coexisting with cassiterite ages for the Xinzhai tin deposit and Re-Os dating of three molybdenite samples separated from the Nanyangtian tungsten deposit to constrain timing and duration of the mineralization.Phlogopite from the Xinzhai tin d... |
