| 摘 要： | 塘唇钨(锡)矿是近年来新发现的一个具有大型规模找矿潜力的石英脉型矿床.矿床产于粤东龙窝花岗闪长岩岩体西部外接触带,赋矿地层为下侏罗统金鸡组碎屑岩,该层位是南岭及邻区石英脉型钨锡矿的最新赋矿地层.在详细的野外地质调查基础上,对矿床含钨石英脉中的白云母进行40Ar-39Ar测年,获得白云母40Ar-39Ar坪年龄为150±1 Ma,等时线年龄为149±2 Ma(MSWD=1.20),它们在误差范围内一致,为南岭地区燕山早期大规模成岩成矿作用高峰期的产物.塘唇钨(锡)矿的发现,不仅拓宽了石英脉型钨锡矿的找矿视野,还有助于完善石英脉型钨锡矿成矿规律和成矿模式,对区域下一步找矿具有重要指导意义.

| Abstract: | The Tangchun tungsten(tin) deposit is a newly discovered quartz vein type deposit and the potential for prospecting is huge. The deposit occurs in the western outer contact zone of the Longwo granodiorite pluton in Eastern Guangdong Province. The ore-hosting strata are the clastic rocks of the Lower Jurassic Jinji formation, which are considered to be the youngest ore-hosting strata in the Nanling and its adjacent areas.On the basis of detailed field geological surveys, a muscovite 40Ar-39Ar plateau age of 150±1 Ma and an isochron age of 149±2 Ma (MSWD=1.20) have been obtained for a W-bearing quartz vein in the deposit, which are the same within the analytical uncertainties. Our 40Ar-39Ar dating results have shown that the Tangchun tungsten (tin) deposit was the product of early Yanshanian large scale petrogenesis and metallogenesis in the Nanling Range. The newly discovered Tangchun tungsten (tin) deposit is of great guiding significance in exploration since it not only broadens our mind in prospecting for quartz vein type tungsten-tin deposit, but also provides an opportunity to thoroughly unravel the metallogenic regularity as well as metallogenic models of the quartz vein type tungsten-tin deposit. |
