摘要
通过对天湖脉石英矿地质特征进行分析,初步得出天湖脉石英矿床成因、控矿条件.断裂构造对天湖脉石英矿有明显的控制作用,红柳河大断裂次级断裂是脉石英矿的有利找矿部位.区域下石炭统雅满苏组、新太古界—古元古界天湖岩群地层在后期构造和热液活动影响下,促使SiO2在成矿有利部位富集成矿.从岩石类型看,花岗闪长岩、二长花岗岩、闪长岩为区内主要成矿有关岩体,脉石英矿主要为岩浆热液晚期成矿.本研究为在马鬃山地区寻找同类型矿床具指导意义.
Abstract
Through the analysis of the geological characteristics of the Tianhu vein quartz deposit,the genesis and ore-controlling conditions of the Tianhu vein quartz deposit are preliminarily obtained.The fault structure has obvious control effect on the Tianhu vein quartz deposit,and the Hongliuhe fault secondary fracture are the favorable prospecting parts of the vein quartz deposit.Under the influence of late tectonic and hydrothermal activities,the Lower Carboniferous Yamansu Formation and the Neoarchean-Paleoprotero-zoic Tianhu rock group strata in the region promoted the enrichment and mineralization of SiO2 in favorable metallogenic sites.From the perspective of rock types,granodiorite,monzonitic granite and diorite are main-ly related to mineralization in the area,and vein quartz ore is mainly formed in the late stage of magmatic hy-drothermal mineralization.This study has guiding significance for finding the same type of deposits in the Ma-zongshan area.
