| 中文摘要: |
| 山东招掖地区是我国黄金主要产地之一,而金矿的形成又与该地区花岗质岩体成因密切相关。通过对岩体分布特征的观察,岩体中锆石特征及其中的熔融、包裹体研究和岩石的重熔实验研究认为,本区与金矿形成密切相关的三大类型岩体:玲珑花岗岩、郭家岭花岗闪长岩和滦家河花岗岩,为来自深部的热流体交代-熔融胶东群变质岩,在不同阶段形成的产物。 |
| 英文摘要: |
| Zhao-Ye area is one of the main Au-producing areas in China. Au-ore here is geneticaly related to granites. Distribution of the granites, study on the zircon within them and its melting inclusions and the remelting experiments reveal that three types (Linglong, Guojialing and Lianjiahe) of granites closely related to Au-deposits are the products of different periods during melting and replacenent of the metamorphosed Jiaodong Group rocks by the deep sourced hydrothermal fluid |
