青海直亥买休玛金矿床矿体特征与找矿前景分析

综合分析直亥买休玛地区金矿成矿地质条件,提取构造、水系沉积物异常和土壤地球化学异常等成矿有利的证据因子,通过对化探异常的检查(槽、硐探工程揭露)、取样分析,发现了金矿体。从探矿工程揭露来看,矿区局部地段砂岩中所形成的硅化、褐铁矿化破碎蚀变带对金矿成矿十分有利,NE向断层十分发育,控制了金矿体的形成和分布,具备破碎蚀变岩型金矿成矿的构造、地层条件,找矿潜力较大。

Discussion on the Ore-body Characteristics and Prospecting Potential of Zhihaimaixiuma Gold Deposit in Qinghai Province

Comprehensively analyzing the metallogenic geological conditions of gold deposit in Zhihaimaixiuma area,we extracted the extraction structure,stream sediment and soil geochemical anomalies such as four kinds of evidence in forming a favorable factor.By geochemical anomalies check（tank,cave exploration project exposed）,sampling analysis,we found a gold ore-body.Exploration works from the exposed point of view,the local mining site in the form of silicified sandstone,limonite fracture zone of the formation of the gold is very beneficial,NE-trending faults developing extra-or-dinarily controlled the formation and distribution of ore bodies.It has the metallogenic structure and stratum condition of forming the clastic altered rock type gold deposit,to find great potential for mining.
