青海直亥买休玛金矿床矿体特征与找矿前景分析

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

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。

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.
