摘要
赣东北是重要的黄金生产基地,金矿类型众多,成矿条件优越。依据成矿物质来源、成矿作用、矿床产出条件、矿石建造和围岩蚀变等因素,将赣东北地区岩金矿床划分为岩浆热液类、火山-次火山热液类、多源热液类和地下热(卤)水渗滤类等4类8型,分述了各类(型)金矿成矿地质特征,总结了沉积建造、构造和岩浆岩对区内金矿的控制作用,指出了赣东北地区金矿找矿方向。
The northest Jiangxi province is the important gold-producing base in China characterized by multiple types of gold deposits, preferential gold ore-forming condition and huge potential for further gold exploration. Based on ore material sources, metallogenesis, occurrences, ore formation and wall rock alteration of gold ore deposits in the northest Jiangxi province they are classified into four types i. e. magmatic hydrothermal gold deposit, volcao-subvolcano hydrothermal gold deposit, multi-sources hydrothermal gold deposit and heat underground water （ brine） infiltrating gold deposit and 8 sub-types and the geological characteristics of the deposits are described and oreforming control of sedimentary formation, structure and magmatic rocks on the formation of gold ore are summarized and gold ore-searching directions in the northeast Jiangxi province are pointed out.
