安徽省绩溪县上金山地区钨钼矿矿化类型及找矿前景分析

     

摘要

上金山钨钼矿位于安徽省绩溪县与旌德县交界地带,是扬子准地台南缘新发现的一处大型层控型矿床。南华系休宁组上段上部地层及燕山早期的花岗闪长岩是本矿床主要控矿因素,赋矿地层岩性为锰钙质砂岩-粉砂岩,该赋矿层位是皖南地区找矿新发现。该矿床已达大型规模,地质、物化探综合信息显示,上金山地区具进一步找矿前景,且在已控制的层控型矿床深部及外围,存在寻找斑岩型钨钼矿及石英脉型钨矿的良好条件,经进一步勘查,矿床资源量将显著增加。%The Shangjinshan Wo-Mo ore deposit lies in beween Jixi County and Jinde County of Anhui Province, is a large strata-bound ore deposit found at the southern fringe of the Yangtze paraplatform. The upper part of the upper member of Xiuning Formation of Nanhua System and the early Yanshanian granodiorite are major ore-control factor of this deposit, and the lithology of ore host is Mn-Ca sandstone-siltstone, which is a new discovery as an ore host in south Anhui. The deposit is big in size. Geological, geophysical and geochemical information as a whole indicates that there is more potential in the Shangjinshan area, and in the depth and periphery of the already controlled strata-bound deposit, there exist good conditions for exploration of porphyry W-Mo ore and quartz vein W ore deposit, after further exploration, the resources will be increased remarkably.
