胶东金矿是全球最大的与花岗岩有关的大型金矿床。前人研究多数与板块碰撞或俯冲联系起来(陈国达,1956),提出“造山带型金矿”或“变质核杂岩”等观点。本文指出,胶东金矿形成于中国东部板块拼合后的大陆,属于陈国达曾厘定的中生代地洼区,受控于一种被笔者称之为“岩浆核杂岩”的构造。胶西北隆起和胶东牟平-乳山隆起是两个明显的“岩浆核杂岩”发育地区,金矿产于“岩浆核杂岩”有利成矿区段。“岩浆核杂岩”构造以成矿花岗杂岩体(180-130 Ma)为核,外围是胶东群-粉子山群变质岩地层(2500-1300
Jiaodong gold deposit is the world’s largest granite-related large-scale gold deposits. Most of the previous studies are related to plate collision or subduction (Chen Guoda, 1956), and put forward the viewpoints of “orogenic belt type gold deposit” or “metamorphic core complex”. This paper points out that the Jiaodong gold deposit was formed in the post-splitting continental China plate, belonging to the Cenozoic depression depression determined by Chen Guoda and controlled by a structure which I call “magmatic core complex”. The Northwest uplift of rubber and Muping-Rushan Uplift are two obvious “magmatic core complex” developmental areas. The gold deposit is located in the favorable metallogenic section of “magmatic core complex”. The “magmatic core complex” structure is composed of the granitoid granitic complex (180-130 Ma) and its periphery is the Jiaodong-Fenzishan group metamorphic rock formation (2500-1300
