摘　　要：在分析区域成矿背景及矿区地质特征的基础上,依据目前生产勘探成果,重点讨论破矿构造发育特征,为后期勘查指出了五处找矿靶区。笔者认为研究区矿床成因类型属接触交代-热液型多金属矿床,后期破矿构造较发育,导致矿体呈现出叠瓦状的分布特征。该认识对前坪矿区的后期勘查具有重要的指导作用,对区域类似矿产的勘查具有重要借鉴意义。Based on analyzing the regional mineralization background and geological characteristics of the deposit,this article focuses on discussing the development characteristics of ore-breaking structures based on current production and exploration results and points out five prospecting target areas for later exploration.The author believes that the genetic type of the deposit in the study area belongs to the contact metasomatism hydrothermal type polymetallic deposit,and the late stage ore breaking structures are more developed,resulting in the distribution characteristics of the ore body showing a layered tile shape.This understanding has important guiding significance for the later exploration of the Qianping mining area and has important reference significance for the exploration of similar mineral resources in the region.
