A Brief Discussion on the Composition and Texture Characteris-tics of Ore Minerals in Qingyangxia Lead Zinc Mine
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.
