摘要
文中从总结雪峰弧形构造带内各典型金矿床地质特征入手,提出一个简明的金矿床分类方案,将区内金矿床类型分为石英脉型金矿与蚀变岩型金矿2个大类,石英脉型金矿又分为顺层与切层石英脉型2个亚类,蚀变岩型金矿分为破碎带蚀变岩型、韧性剪切带蚀变岩型与破碎蚀变砂岩型3个亚类,并阐述了不同类型的金矿与不同的地层岩性及构造组合之间的关系,以期指导区内金矿床勘查及开发工作。
Based on the conclusion of geologic characteristics of typical gold deposits, the contribution puts forward a simple classification scheme. In the scheme, there are two basic types of gold deposit, which are quartz-vein type deposit and altered rock type deposit. The quartz-vein type deposit can be divided into two subtypes of bedding quartz-vein subtype and cutting quartz-vein subtype. The altered rock type deposit can be divided into three subtypes of cracking belt altered rock subtype, ductile shear belt altered rock subtype and cracking altered sandstone subtype. The relationship between different types of gold deposits, different formation lithology and structure combination is explained.
