西峡县大庙金矿矿床地质特征及矿床成因浅析

Geological Features And Ore Deposits Of Deming Gold Deposit In Xixia County

大庙金矿区位于华北古板块与扬子板块长期活动带的接合部位一秦岭多金属成矿带东段朱夏断裂带中部,北秦岭构造亚带二郎坪地体东段北侧,本区构造、岩浆活动分为多期,成矿地质条件良好。文中对大庙金矿区成矿地质背景、成矿地质特征、找矿标志等进行了简单探讨,总结了矿床成因,认为本区金矿为火山热液型金矿。

Dawmiao gold deposit is located in the middle of the Zhuhai-Xizang fault zone in the east of the Qinling polymetallic metallogenic belt and in the north of the eastern segment of the Erlangping landform of the North Qinling structural belt,Zone structure,magmatic activity is divided into multi-stage,metallogenic geological conditions are good.This paper briefly discusses the metallogenic geological background,metallogenic geological characteristics and prospecting signs in Dawmiao gold mining area,and summarizes the genesis of the deposit.It is concluded that the gold deposit in this area is a volcanic hydrothermal gold deposit.
