黑龙江省某地区钼、铅锌多金属矿(化)点地质特征及找矿标志

研究区位于小兴安岭—张广才岭多金属成矿带之翠宏山—二股铁、有色金属成矿亚带(也称铁力—玉泉有色金属、贵金属成矿带)的中南段,呈南北向带状展布。成矿带中区域上发育三期成矿作用,加里东中期成矿作用、印支晚期成矿作用和燕山期成矿作用,是黑龙江省重要的铅、锌、银、铁、钨、钼等多金属成矿带。测区先后发现了前进东山铅锌矿点、前进先锋沟铁矿化点、牛奶沟钼矿点、九小工队钼矿化点。本文以牛奶沟钼矿点、九小工队钼矿化点为例总结了五三零和寒月林场地区钼、铅锌多金属矿化点的地质特征并确定了其成矿规律与找矿标志。

Geologic features and prospecting criteria of Mo-Pb-Zn polymetallic deposit in Zhangguangcailing area,Heilongjiang Province

The study area is located in middle-south Cuihongshan-Ergu iron and nonferrous metal metallogenic belt which belongs to Xiaoxing’anling-Zhangguangcailing polymetal metallogenic belt,and it spreads as the direction of south-north.There are three stages of metallogenic period： the middle Caledonian period,the late Indosinian period and the Yanshan period.This area is an important metallogenic belt in Heilongjiang Province,which is riched in Pb,Zn,Ag,Fe,W,Mo and so forth.We ordinally discovered Qianjindongshan Zn-Pb mineralized spot,Qianjinxianfenggou Fe mineralized spot,Niunaigou Mo mineralized spot,Jiuxiaogongdui Mo mineralized spot in the measured area.Taking the Qianjindongshan Zn-Pb deposit and Niunaigou Mo deposit for example,this paper presents a summary of geological feature of Mo and Pb-Zn mineralized spot in Wusanling area,and works out its regularity of ore formation and indicator for deposit.
