| 摘 要： | 南岭东段是世界著名的钨多金属矿集区，多轮的地质工作使区内找矿和研究程度极高，找矿难度极大。南山钨钼多金属矿床是近年来中国地质调查局在该区实施钨多金属矿调查评价中根据岩体型（地下室）找矿模型找到的具有中大型远景的钨钼多金属矿床。钻探验证成果显示该矿床除地表分布的石英脉型钨钼多金属矿体外，在深部燕山晚期岩体中发育了大规模的岩体型（云英岩型和花岗岩型）钨钼多金属矿体，矿区燕山晚期花岗岩自上而下分为白云母化、绿泥石化和钾长石化三带，云英岩型钨钼多金属矿体分布在白云母化带，赋矿岩体为细粒二云母花岗岩；花岗岩型钨钼多金属矿体分布在绿泥石化带和钾长石化带，矿体为细粒浸染状黑云母二长花岗岩和细粒钾长石花岗岩，矿石矿物主要有黑钨矿、辉钼矿、锡石、辉铋矿、方铅矿、闪锌矿、白钨矿、黄铜矿、黄铁矿等；初步研究表明该岩体型钨钼多金属矿体可能为深部含矿岩浆经分异作用形成，矿床具有品位一般、规模大的特点，成矿元素复杂，主要为W － Mo － Sn － Bi 组合，并富含Pb，Zn，Ag，Nb 等。该矿床的发现不仅填补了南岭东段地区找矿新突破，而且对整个南岭乃至华南地区钨钼多金属矿找矿具有重要的指导作用。

| Abstract: | The eastern Nanling mineralization zone is the world s leading tungsten-polymetallic ore concentration area.Many rounds of geological prospecting work make the region with a high degree of research and extreme difficulty in prospecting. The Nanshan W-Mo polymetallic deposit,which is a large granite-type deposit,was found by Nanjing Center,CGS during the investigation of tungsten polymetallic ores according to the model of"the tungsten basement"under the"five-floor structured wolframite-quartz veins"in this area in recent years.The results of drilling verified that under the quartz-vein type W-Mo- polymetallic ore bodies exposed near the surface,at a deeper level of the Nanshan fine-grained two-mica granite,there develops a large-scale greisen type and granite type W-Mo polymetallic ore body.The Yanshanian Nanshan granite here is divided into three alteration zones,i.e.,from top to bottom,the muscovitization zone,the chloritization zone and the K-feldspathization zone. The greisen type W-Mo ore body occurs in the muscovitization zone.The granite type W-Mo polymetallic ore body occurs in the chloritization and K-feldspathization zones.The major ore minerals are wolframite,molybdenite,sheelite,cassiterite,bismutinite, galena,sphalerite,chalcopyrite,pyrite,etc.A preliminary study indicates that the formation of the greisen type and granite type ore body might be related with the differentiation of deep-seated ore-bearing magma.The Nanshan W-Mo polymetallic deposit is characteristic of low-grade,large-scale and complex chemistry,with a W-Sn-Mo-Bi assemblage,enriched in Pb,Zn,Ag,Nb.The discovery of Nanshan deposit is not only a breakthrough of prospecting in the eastern Nanling,but also an important guide in theSouth China, s W-Mo-polymetallic ore prospecting work as a whole. |
