摘要

摘要:
与胶东金矿有密切关系的玲珑片麻状花岗岩、栾家河二长花岗岩、郭家岭花岗闪长岩、上庄二长花岗岩4种类型花岗岩中矿物包裹体的发育程度、类型、大小及其特点, 以及包裹体的显微测温结果, 反映出玲珑岩体是经历了高级区域变质作用形成的重熔型花岗岩, 郭家岭岩体是由高温、高粘度岩浆结晶成岩的。栾家河岩体是由一种富CO₂的高温、高粘度的岩浆中结晶演化而来, 岩体的侵入深度也较浅。上庄岩体形成温度压力较低。

Abstract:
In eastern Shandong Province (Jaodong area), there are distributed Linglong gneissic granite, Luanjiahe granite, Guojialing diorite and Shangzhuang monzonitic granite, which have close relation with Jiaodong gold mine.According to developing degree, type, size and characteristics of mineral inclusions, and based on temperature-measuring result by microscope, it is indicated that the Linglong rock mass was formed by remelting of granite caused by high regional metamorphism, the Guojialing rock mass was derived from crystallization of a high-temperature and high-viscosity magma, the Luanjiahe rock mass was crystallized from high-temperature, high-viscosity and CO₂-rich magma at a relatively small depth, and the Shangzhuang rock mass was formed at a low-temperature and lowpressure condition.
