摘要
在对胶东地区成矿地质背景、各种致矿地质-构造事件在时间和空间上的耦合、金矿床点时空结构、内在成生联系及时空配置关系研究的基础上,厘定了胶东金矿的概念、特征及主要表现形式,并对其进行了阐述,系统地提出了胶东地区金矿成矿的理论体系,即独具特色的四位一体构造叠置成矿背景、挤压-伸展手风琴式构造-岩浆-成矿作用方式和壳-幔流体多种来源的成矿物质,概括起来就是地质条件、定位方式和物质来源的有机耦合共同构成了胶东地区金矿成矿理论体系,这一理论解释了为何在该区形成巨量金矿的原因,是对胶东地区金矿理论研究的创新性成果。
On the basis ol studying geological background ol ore lorming, coupling ol various tectonic events in time and space, time and space structures ol gold deposit, internal relations and spatio - temporal relationship in Jiaodong area, the concept, characteristics and main lorms ol gold deposits in Jiaodong area have been introduced. The theoretical system ol gold mineralization in Jiaodong area has been put lorward,they are ＂ lour in one＂ tectonic superimposed metallogenic background, stretch extrusion accordion style tectonic magmatic mineralization, and shell mantle lluid lrom many sources ol or^ - lorming materials. The organic coupling ol geological conditions, loca-tions and material sources constitutes the system ol metallogenic theory ol gold deposits in Jiaodong area. This theory explains the formation ol massive gold deposit in Jiaodong area. It is innovative achievement in the theoretical re-search ol regional gold deposits.
