胶东西北部地区花岗岩类岩石成岩的物理化学条件

PHYSICAL AND CHEMICAL CONDITION FOR THE FORMATION OF GRANITES IN THE NORTHWEST OF JIAODONG REGION SHANDONG PROVINCE

摘要:

胶东西北部地区发育有不同类型的花岗质岩石。研究表明,这些花岗质岩石是经胶东群在不同的物理化学条件下熔融形成。本文利用热力学计算公式及有关实验资料,说明不同花岗质岩石形成时的 T、P、fo_2、f_(H_2O)。

Abstract:

There are various types of granites in the Northwestern Jiaodong district.The study has shown that these rocks were formed by partial melting of the Jiaodong group.This paper gives the conditions at which the rocks were formed,including T,P,fo_2,f_(H_2O) by the calculation with thermodynamic formulas and some experimental results.
