陕西省双王金矿Ⅴ号角砾岩体找矿潜力分析

Analysis of prospecting potential of Ⅴ horn conglomerate in Shuangwang Gold Mine of Shaanxi Province

双王金矿为一大型、易采易选的低品位金矿体,矿床直接赋存层位是中泥盆统古道岭组,矿体隐伏或侧伏于含铁白云石胶结角砾岩带中,依据角砾岩成因将其划分为构造角砾岩、液压致裂角砾岩和气液引爆角砾岩三大类,本文通过分析Ⅴ号角砾岩体的特征、矿体赋存特点、矿化富集规律以及空间展布关系,矿体赋存在液压致裂角砾岩中,Ⅴ号角砾岩体具有向东侧伏的趋势,矿化与矿体厚度具有一定相关关系。

Shuangwang Gold Mine is a large low-grade gold orebody with easy mining and easy selection.The ore-body directly exists in the Middle Devonian Gu daoling Formation.The ore-body is concealed or lateral in the iron-bearing dolomite cemented breccia belt.According to the breccia genesis,it is divided into three categories:tectonic breccia,hydraulic fracturing breccia and gas-liquid detonating breccia.In this paper,the characteristics of Ⅴ horn breccia,orebody occurrence,mineralization enrichment and spatial distribution are analyzed.
