通过对胶东地区与金矿有关的中生代侵入岩构造地质学、岩石化学、同位素年代学等地质信息资料的分析研究，认为玲珑昆嵛山花岗岩属于I型和S型花岗岩，郭家岭花岗岩总体上归属于I型花岗岩类；两者具有不同的源岩，形成的环境为洋壳俯冲引起的火山岛弧环境、大陆碰撞环境和弧后拉张性质的大陆边缘环境；玲珑昆嵛山花岗岩形成于侏罗纪；郭家岭花岗岩形成时代为早白垩世；从岩石构造组合的概念，玲珑昆嵛山花岗岩应划为玲珑昆嵛山造山早期片麻状花岗岩组合；郭家岭花岗岩应为郭家岭造山中期弱片麻状花岗闪长岩花岗岩组合。

T hrough analysis and study on tectonic geology ,petrochemistry ,geochronology and other geo‐logical information data of Mesozoic instrusive rocks which has relation with gold deposit in Jiaodong area , it is regarded that Linglong Kunyushan granite belongs to Itype and S type granites ,w hile Guojialing granite belongs to Itype granitoids .They have different source rocks ,and the forming environments are is‐land arc environment and the continental collision caused by oceanic crust subduction and continental mar‐gin with the property of arc extension .Linglong Kunyushan granites were formed in the Jurassic ,and Guojialing granites were formed in the early Cretaceous .From the concept of rock combinations ,Linglong Kunyushan granites should be classified as gneissic granodiorite combination in early Linglong Kunyus‐han orogenic period ;while Guojialing granite should be classified as weak gneissic granodiorite granite combination in middle Guojialing orogenic period .
