摘要
为研究八卦庙金矿床的控矿构造及与矿化富集的关系,在总结矿体地质特征的基础上,采用地质统计分析对照的方法,对矿体富集的规律和控矿构造进行了剖析。结果表明,矿区内存在三种不同类型的金矿石,分别受不同的构造系统控制,而NE向节理密集带所构成的节理脉型金矿石是八卦庙金矿床主体,其与顺层揉皱石英脉叠加后,构成了较高品位的矿化富集中心;同时NE向节理脉及密集带的空间位置、规模和产状,亦控制了整个矿床矿化富集带的分布,即由高往下,矿体富集中心向NW方向偏移,并且有发散的趋势,深部及外围找矿的主要目标应以NE向节理裂隙构造为主。
In order to study the relationship between the ore-controlling structure and mineralization enrichment of Baguamiao gold deposit,based on the summary of the geological characteristics of the ore bodies,the ore enrichment regularity and ore controlling structure are analyzed with geo-statistical analysis and comparison method in this paper.The results show that there are three different types of gold ore in the mine,controlled by different structural system,respectively.The joint band type gold ore,controlled by NE joint concentrated zone is composed of the major part of Baguamiao gold deposit.And after superposition with crumpled bedding quartz,they constitute of a higher grade mineralization center.At the same time,the spatial position,scale and occurrence of NE joint vein and concentrated zone also control the distribution of the mineralization enrichment zone of the deposit.From the high to low places,ore body enrichment center shifts to NW direction with a trend of divergence.The main prospecting target in the deep and periphery should be focus on NE joint and fissures.
