摘要
大坞尖钨矿床位于扬子陆块南缘与华夏古陆块的接合部位,是皖南地区典型的层控矽卡岩型矿床,近年来该地区钨多金属矿的勘探方面取得很大的突破。本次工作新发现了赋存在南沱组中段中的厚度大、延伸较稳定的钨矿体,为宁国地区首次发现。通过与已知矿体对比,结合最新深部勘查成果,认为新发现深部矿体找矿潜力大。该发现打开了矿区新的找矿空间,为该地区类似矿床的寻找提供新的思路。
Dawujian deposit is a typical stratabound skarn tungsten deposit in the south of Anhui Province,which locates in the joint part of the Cathaysia Block and the southern margin of the Yangtze block.There are great breakthroughs in ore prospecting and exploration about tungsten-molybdenum polymetallic deposits recently.In this work,a new tungsten ore body was found in the 2rd Member of Nantuo Formation.It is the first discovery in Ningguo area.Based on the existing deep exploration results,by comparing with known ore bodies,it is considered that the newly discovered deep ore body have great prospecting potential.The discovery opens up a new prospecting space and provides a new idea for the exploration of similar deposits in this area.
