| 摘 要： | 位于内蒙古中部的李清地铅锌银矿床近期找矿获重要进展,该矿床为与中生代陆相火山作用有关的浅成低温热液型,以大脑包山为中心发育的环状与草药放射状断裂构成的火山机构制约了铅锌银矿化的产出.以往一直认为控矿断裂走向为NE向,虽投入大量勘探工程,仅获得小型独立银矿储量.研究发现,其成矿规律表现为北东向（基底）构造控制矿带,北西向构造控制矿体,主要铅锌银矿体赋存于NW向断裂中,NW向构造与NE向构造的交汇部位附近形成富厚矿体,这一控矿构造的重新认识,直接导致了李清地矿床找矿的新突破,发现富厚铅锌、银、金矿体.目前矿区相继发现多条NW向含矿断裂,显示出整个李清地矿区具有大型以上的铅锌、金、银矿的远景.

| Abstract: | Major advances have been made in mineral exploration in the Liqingdi lead-zinc-silver deposit,central Inner Mongolia in recent years.This deposit is an epithermal deposit related to Jurassic continental volcanism.The mineralization is controlled by a volcanic edifice formed by circular and radial fractures centering on the Danaobaoshan volcano.Previously it was considered that the ore-controlling fractures strike NE.Although large amount of exploration work had been done,only reserves of small silver deposits were obtained.Study shows that the NE-trending (basement) fractures control the ore zones,while the NW-trending fractures control orebodies.The major lead-zinc-silver orebodies occur in the NW-trending fractures and oreshoots occur near the intersection site of the NW-and NE-trending fractures.This new idea of the ore-controlling fractures leads to a new breakthrough in mineral exploration in the Liqingdi deposit and discovery of lead-zinc-silver oreshoots.At present several NW-trending ore-bearing fractures have been found successively in the ore district,indicating that the entire Liqingdi ore district has the potential of becoming a superlarge lead-zinc-silver deposit. |
