摘要
玲珑、郭家岭超单元花岗岩的源岩均为胶东岩群变质岩;玲珑超单元花岗岩表现出岩石的不均匀性,其成因为原地、半原地交代-重熔型花岗岩;郭家岭超单元花岗岩则属于有幔源物质参入的同熔型花岗岩。两个花岗岩均经历了多期构造-岩浆作用,最终形成于燕山期;郭家岭超单元最终形成晚于玲珑超单元花岗岩。
The proto-rock of Linglong and Guojialing super-unit granites is the same of metamorphic rocks of Jiaodong group. The former is in-situ replacement, semi-in-situ replacement-remeltin characterized by heterogeneity. The later is syntectic granite incorporated with mantle materials. all exposed to multiple tectonism and magmatism and take the final shape in Yanshanian Period. gg Th ranlte ey are However, Guojialing super-unit granite took shape later than Linglong super-unit granite.
