摘要
位于内蒙古察右前旗成堂地铅锌银多金属矿是经过1∶5万袁家房子等四幅矿调发现的。矿体及矿化蚀变带主要分布在燕山期钾长花岗岩与集宁岩群大理岩的外接触带上,地表出露三条带状矿(化)体,呈透镜状、脉状、囊状等,直接找矿标志为铁锰帽。矿床受岩体、构造、火山机构等多种因素控制,在北西向断裂与北东向构造交汇部位,常出现富矿体。
A lead-zinc-silver polymetallic mine was found after accomplished Yuanjiafangzi and other three 1：50000 geological mine survey in Chayouqi banner of Inner Mongolia .Ore mineralization and alteration are mainly distributed in external contact zone of Yanshanian moyite and marble of Jining rock group, outcrop of three strip ore bodies, a lenticular, vein, cystic and so, for direct prospecting signs of iron and manganese cap. Ore deposits was controlled by intrusion, tectonic, volcanic apparatus, and other factors .In the intersections of NW- and NE- trending structures often occurred rich ore body.
