摘要
杨发成金矿矿体赋存于哀牢山断裂带(F_1)之次一级的层间构造破碎带中,矿体沿构造破碎带分布,矿体近矿围岩为元古界小羊街组上亚组(Ptx^b)石英岩。矿床成因属中-低温热液充填型矿床。沿哀牢山断裂(F_1)及其次级断裂带的土壤地球化学异常。
The ore body of Yangfacheng Au deposit is in the secondary interlayer structural fracture zone of Ailaoshan fault zone( F_1). The ore body is distributed along the structural fracture zone. The near wall rock of ore body is the quartzite of Proterozoic Xiaoyangjie Formation Upper Sub-Formation( Ptxb). It belongs to the middlelow T hydrothermal filling ore deposit in genesis. The soil geochemical anomaly along Ailaoshan Fault and the secondary fault zone is the most direct prospective criterion.
