安徽省南陵县汤村徐锌多金属矿地质特征及找矿方向

Geological characteristics and prospecting direction of Tangcunxuzinc polymetallic deposit in Nanling County,Anhui Province

勘探工作在安徽省南陵县汤村徐一带新发现了锌多金属矿床,通过钻探验证和分析测试,圈定了3个锌铅矿(化)体,1个钼矿体。总结了该地区前矿区地质特征和矿床特征,发现该矿中锌矿(化)体受泥盆系五通组和石炭系黄龙船山组界面控制,与角砾状花岗闪长斑岩的侵入密切相关,并受断层F 2破坏,钼矿体形成于花岗闪长岩体内部。经研究认为断层F 2以东方向为锌矿体NW向延伸有利部位,ZK104孔周围深部是寻找铜钼矿重要位置,且断层F 2以西是寻找接触交代型矿体有利部位。研究可为该区域找矿工作提供新的思路。

Exploration work has newly discovered zinc polymetallic deposit in Tangcunxu,Nanling County,An hui Province.Three zinc lead ore(mineralized)bodies and one molybdenum ore body have been delineated after drilling verification and analysis testing.The geological characteristics and deposit characteristics of the mining area were summarized,and it is found that the Zn ore is controlled by Wutong Formation in Devonian and Huang\|longchuanshan Formation in Carboniferous.Besides,the Zn ore is closely related to the intrusion of brecciform granodiorite porphyry and damaged by fault F 2,while the Mo ore body is formed inside the granodiorite.It is considered that the east area of fault F 2 is the favorable position for the extension of the Zn ore body in NW direction,and the deep area around ZK104 borehole is the important position for Cu and Mo ore.The west area of fault F 2 is the favorable position to search for contact metasomatic ore body,which provides a new idea for the prospecting work in this area.
