摘要
万村金矿床产于华北陆块南缘熊耳山金矿化集中区,花山花岗岩体的南部边缘。通过综合分析、研究矿区探(矿)采(矿)及前人资料,本区金矿具有造山带型金矿的特征。金矿形成于岩体侵入之后,矿体在构造形成过程中由含矿热液充填形成,太华群仍是本区金矿的主要矿源层,花山花岗岩体在成矿过程中提供了重要的成矿物质。矿体主要分布在含矿蚀变带中下部和底部,根据区内化探资料分析,矿体中深部存在第二矿化富集段,显示该区中深部具有较大的找矿潜力。
Wancun gold deposit occurs inside Xiong'ershan gold mineralized concentrate district on the south-ern margin of North China Craton,and on the southern margin of Huashan granite body. According to the comprehensive analysis and research on the previous works and documents related to prospecting and mining in the mining area,it appears that the gold deposits in this area are orogenic belt type deposits.The gold de-posits are formed after the intrusion of rock bodies,and the orebodies are formed by ore-bearing hydrother-mal fluid during the structural formation.Taihua Group remains the primary source bed of gold deposits in this area,and Huashan granite body provides essential ore-forming materials during the mineralization.The orebodies are mainly distributed at the middle-lower part and the bottom of ore-bearing alteration belt. According to the analysis on the documents related to geochemical prospection of this area,the second mineralized concentrate block exists in the deep part of the orebody,and it appears that the middle-lower part of the area has great prospecting potential.
