摘要
本文旨在阐明维摩寺—草庙浅成—超浅成 A 型花岗岩形成的物理化学条件。依据岩石化学和矿物化学特征,通过各种方法的计算,对岩体形成的温度、氧逸度、水逸度、压力、熔体中水含量、岩体定位深度和岩体剥蚀程度等,给出了具体的量值,提供了 A 型花岗岩形成环境的一个实例。
This paper aims at discussing the physical-chemical conditions of weimosicaomiao hypabissal-ultrahypabissal A-type granitoid in the evolution.Temperatues of mineral crystallization,oxygen fugacities of magmatic stage,water fugacities,pressures,water contents in melts,emplacement depths of rock massrs and denud- ation degree of the masses are caculated with different methods based on the petrochemistry and mineral-chemistry.This is a example of the forming environment for A-type granites.
