下柳沟-白柳沟铜多金属矿区地质特征及找矿潜力分析

The analysis of geologic feature and ore prospecting in Xialiugou-Bailiugou copper polymetallic ore deposit

为探索矿区的找矿潜力,通过对下柳沟-白柳沟铜多金属矿区地质特征、地球物理及地球化学异常特征、矿床特征及成因等方面的研究,认为该地区成矿与火山岩有关,产于中酸性火山岩和中基性火山岩接触带中,成群成带分布是本区内矿产的基本规律。与Cu,Pb,Zn有关的矿化为黄铜矿化、方铅矿化、闪锌矿化、孔雀石化等。矿床产于加里东期,根据矿床地质特征及成因分析,讨论了该地区铜多金属矿床的类型,认为该地区具有一定的找矿前景。

To explore the potential of mineral deposits,we analyzed the geological characteristics,geophysical and geochemical anomaly characteristics,characteristics and genetic analysis of ore deposit in Xialiugou- Bailiugou copper polymetallic ore deposit mining area. The mineralization in the region is related to volcanic rock,which resulted from intermediate- acid volcanic rocks and basic volcanic rocks in the contact zone. Grouped zonal distribution of the mineral is the basic rule in this area. The main mineralizations related to Cu,Pb and Zn are chalcopyrite,galena,sphalerite and Malachite formed during Caledonian period. According to the analysis of the geological feature and formation causes of the deposit,the type of copper polymetallic deposit is discussed. The region has ore prospecting in the future.
