长汉卜罗银铅锌矿床位于华北克拉通北缘。矿体受 EW、NE 向断裂控制，主要以脉状、透镜状赋存于流纹斑岩、花岗闪长岩、安山岩内及不同岩性接触带。金属矿物以方铅矿、闪锌矿、黄铁矿为主，其次为黄铜矿、毒砂、黝铜矿、银黝铜矿等。围岩蚀变主要在矿脉两侧发育，包括黄铁矿化、绢云母化、硅化、绿泥石化、绿帘石化、碳酸盐化等。在找矿方向上应加强对 EW向和 NE 向断裂破碎带中矿体的寻找，同时在矿区深部南东方向具有更好的找矿前景。

Changhanboluo Ag-Pb-Zn deposit is located in the northern fringe of North China Craton.The ore-bodies are controlled by EW-and NE-trending faults and occur in veined or lenticular shape inside rhyolite porphyry,granodiorite,andesite and the contact zones of different rocks.The metal minerals mainly include galena,sphalerite and pyrite,with minor chalcopyrite,arsenopyrite,tetrahedrite and freibergite.Wall rock alteration is well developed on both sides of the veins,dominated by pyritization,sericitization,silication, chloritization,epidotization,carbonatation,etc.It is suggested that the future prospecting works shall focus on the orebodies inside the EW-and NE-trending faulted fracture zones,and the southeast part in deep level of the mining area has more favorable prospecting prospect.
