摘要
青羊峡铅锌矿床是位于秦岭造山带西成矿田西南部的和碳酸岩、碎屑岩沉积建造相关的层控型铅锌矿床,矿床成因类型属热水沉积—改造型矿床,矿床的产出及其分布基本受层位控制。矿区矿体表现出同生沉积成岩以及后期改造成矿的特点。本文以青羊峡铅锌矿床为例,剖析矿体的矿石矿物组成以及矿石组构特征,总结了区域变质作用对岩矿石结构、构造的影响。通过对其矿石组构特征的分析与总结,以期为该区矿床地质成因研究以及勘查找矿工作提供一定的参考。
The Qingyangxia lead—zinc deposit is a layer controlled lead—zinc deposit located in the southwest of the Xicheng ore field in the Qinling orogenic belt,related to carbonate and clastic sedimentary formations.The genesis type of the deposit belongs to the hydrothermal sedimentary transformation type,and the occurrence and distribution of the deposit are basically controlled by the layer.The ore bodies in the mining area exhibit the characteristics of syngenetic sedimentation,diagenesis,and later transformation and mineralization.This article takes the Qingyangxia lead—zinc deposit as an example to analyze the mineral composition and fabric characteristics of the ore body,and summarizes the influence of regional metamorphism on the structure and structure of rocks and ores.By analyzing and summarizing the characteristics of its ore fabric,it is hoped to pro⁃vide some reference for the study of geological genesis and exploration and prospecting work of the deposit in this area.
