辽宁高家岭多金属矿地质特征及找矿标志

Geological characteristics and prospecting signs of Gaojialing Polymetallic Deposit in Liaoning province

高家岭矿床于2011—2012年被发现并勘查,是以铜金银为主要有用元素的隐伏次火山热液型多金属矿,矿石类型可分为金银铜型矿石和铜银型矿石,不同类型矿石具有垂直和水平分带特征。矿床的形成受基底地层、构造、岩浆岩联合控制。蚀变火山角砾岩筒、次级断裂构造、次火山岩体是成矿有利因素;Au、Ag、Cu、Pb、Zn元素异常套合部位和高磁负异常与激发极化异常套合部位是成矿有利地段;碳酸盐化、硅化、绢云母化及多金属硫化物蚀变是矿(体)化赋存的主要标志。

Gaojialing deposit is found and explored in 2011--2012 years. The deposit genesis type is concealed subvolcanic hydrothermal type with main useful elements of gold, silver and copper. The ore type includes gold-siver copper ore and copper-silver ore. Different types of ore have characteristics of vertical and horizontal zoning. The formation of ore deposit is controlled by basement strata, structure and magmatic rock. Altered volcanic breccia pipe, secondary fracture structure and subvolcanic rock mass are favorable factors for mineralization; Au, Ag, Cu, Pb, Zn element anomaly nested department and magnetic negative anomaly and induced polarization anomaly nested department are favorable locations of mineralization. Carbonatization, silicification, sericitization and polymetallic sulfide alteration are the main signs of mineralization.
