【摘要】 李贵福钨锡多金属矿赋存于都庞岭复式花岗岩体东部。矿床类型主要为云英岩-石英脉型。通过对矿石中辉钼矿Re-Os同位素测年,获得等时线年龄为(211.9±6.4)Ma(n=7,MSWD=4.1),模式年龄的加权平均值为(213.3±2.9)Ma(MSWD=4.0)。结果显示成矿作用发生在印支期,表明都庞岭地区存在早中生代钨锡多金属成矿事件。更多还原

【Abstract】 The Liguifu tungsten-tin polymetallic deposit occurs in the east of Dupangling granite,being mainly of the greisen-quartz vein type.The precise Re-Os isotope dating of molybdenite from the ore shows that the isochron age is(211.9±6.4)Ma(n=7,MSWD=4.1),and the weighted average of model ages is(213.3±2.9) Ma(MSWD=4.0).The isochron age suggests that mineralization took place in the Indo-Chinese epoch,and the result demonstrates that Early-Mesozoic tungsten-tin polymetallic mineralization did happen in Dupangling area.更多还原
