【摘要】 大湖金矿区位于东秦岭多金属成矿带东段,矿产资源丰富,为我国重要金、银、铅、锌、铜等矿产地,太古宇太华岩群是金矿重要的矿源层及赋存层位,金的富集规律受控矿构造、含矿断裂特征矿化阶段及围岩蚀变等多种因素制约。从该区金矿地质特征、矿床成因及找矿方向研究认为,区内燕山期强烈的岩浆活动,为太华群地层中金的活化、迁移,富集提供了热动力,另外区内多组破碎带为金矿形成提供了良好的成矿空间,是重要的控矿因素,根据金矿的富集规律,提出了今后找矿与勘探的理论依据。更多还原

【Abstract】 The Dahu Au deposit lies in the eastern sector of the east Qinling polymetallic metallogenic zone which is rich in such mineral resources as Au, Ag, Pb, Zn and Cu and so on. The Archean Taihua Rock Group is both source bed and host rock. The Au deposit is controlled by structure and fractured zone. The Yenshanian magmatism was responsible for remobilization, migration and enrichment of Au.更多还原
