胶东招掖大型金矿集中区的形成是一个多期次、多来源的复杂过程。胶东群正变质岩的原岩———太古代拉斑玄武岩为初始矿源岩 ;太古代 元古代胶东群、荆山群和粉子山群变质岩为中间矿源岩 ;中生代剪切重熔岩浆岩———玲珑型花岗岩和郭家岭型花岗岩是成矿物质的主要直接提供者 ;郭家岭型花岗岩还起到“热机”作用 ;而蓬莱群及滦家河型花岗岩提供成矿物质的可能性较小。金的成矿作用是在古老地幔分异出的太古代拉斑玄武岩基础上 ,经韧性剪切→区域变质→岩浆重熔等构造热动力作用逐步富集的过程。岩浆侵入后 ,形成以岩体为中心的凸形热场 ,是流体成矿作用的主要动力之一。成矿流体的流速可以促进混合热液的生长 ,剪切破碎带是强烈输运 反应耦合成矿的有利场所。地幔富C H O流体、中 下部地壳富硅流体、浅 表部富硫流体 3个层次流体相互沟通、混合 ,导致流体循环持续时间增长 ,萃取围岩有用元素增多 ,成矿元素丰度升高 ,并最终形成胶东招掖金矿集中区 The formation of a large gold deposit in the middle of the Jiaodong Zhaoye is a complicated process with multiple sources and multiple sources. The original rocks of Archean metamorphic rocks in the Jiaodong Group --- the Archean tholeiite basalts are the initial source rocks; Archean Proterozoic Jiaodong Group, Jingshan Group and Fenzishan Group metamorphic rocks are intermediate source rocks; Mesozoic shear-re- - Linglong granite and Guojialing granite are the main direct suppliers of ore-forming materials. Guojialing granite also plays a role of “heat engine.” The Penglai Group and Luanjiahe granites are less likely to provide ore-forming materials. The gold mineralization process is based on the ancient mantle-derived Archean tholeiite basalts and is enriched gradually by thermodynamic forces such as ductile shear → regional metamorphism → magma remelting. Magmatic intrusion, the formation of rock as the center of the convex thermal field, is one of the main driving force of fluid mineralization. The velocity of ore-forming fluids can promote the growth of mixed hydrothermal fluids. Shear fractured zone is a favorable site for intensive transport reaction and metallogenesis. The mantle-rich CHO fluid, the middle-lower crust enriched silicon-rich fluid and the superficial sulfur-rich fluid communicate and mix with each other, resulting in the increase of the fluid circulation duration, the increase of the useful elements in the extracted surrounding rock and the increase of metallogenic element abundance The final formation of Jiaodong Zhaoye gold concentrate area
