山东胶东金矿成矿理论体系

Metallogenic System of Jiaodong Gold Deposit in Shandong Province

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。

Abstract:

On the basis of studying geological background of oreforming, coupling of various tectonic events in time and space, time and space structures of gold deposit, internal relations and spatiotemporal relationship in Jiaodong area, the concept, characteristics and main forms of gold deposits in Jiaodong area have been introduced. The theoretical system of gold mineralization in Jiaodong area has been put forward, they are "four in one" tectonic superimposed metallogenic background, stretchextrusion accordion style tectonicmagmaticmineralization, and shell mantle fluid from many sources of oreforming materials. The organic coupling of geological conditions, locations and material sources constitutes the system of metallogenic theory of gold deposits in Jiaodong area. This theory explains the formation of massive gold deposit in Jiaodong area. It is innovative achievement in the theoretical research of regional gold deposits.
