中文摘要:
      安徽西湾铅锌矿床为庐枞矿集区新发现的赋存于基底地层中的大型铅锌矿,4个主矿体初步估算铅+锌推断金属量97.4万吨,是该地区首次在东马鞍山组灰岩中发现的铅锌多金属矿。该区第四系覆盖厚,勘查手段有限,找矿难度大。本文利用钻孔岩石样的分析结果,对矿区的微量元素含量、分布特征进行研究,提取了岩石样中包含的有用成矿信息。微量元素含量特征及因子分析结果表明,As、Sb、Pb、Zn、Ag、Mo与铅锌矿成矿关系密切,为铅锌矿成矿的指示;上述元素的含量分布特征显示,矿区成矿热液运移方向总体为自南西向北东,指示了北东向有进一步找矿潜力,明确了该区进一步找矿的方向。
英文摘要:
      The Xiwan lead-zinc mine in Anhui is a newly discovered large-scale lead-zinc mine in the basement strata in the Luzong ore concentration area. The 4 main ore bodies have a preliminary estimate of 974,000 tons of lead+zinc inferred metal, which is the first time this area has been in the east. Lead-zinc polymetallic ore found in limestone of Ma’anshan formation. The quaternary system in this area has thick coverage, limited exploration methods, and difficult prospecting. This paper uses the analysis results of the drilled rock samples to study the trace element content and distribution characteristics of the mining area, and extracts the useful mineralization information contained in the rock samples:the trace element content characteristics and factor analysis results show that As, Sb, Pb, Zn, Ag, Mo are closely related to lead-zinc deposits and are indicative of lead-zinc deposits; the content distribution characteristics of the above elements show that the migration direction of ore-forming hydrothermal fluids in the mining area is generally from southwest to northeast. It indicates that there is further prospecting potential in the NE direction, and defines the direction of further prospecting in this area.
