引言闪石族矿物是火成岩与变质岩的主要造岩矿物之一。本世纪六十年代以来,人们对闪石族矿物越来越重视,并进行了广泛的研究。这些研究主要是探索闪石的化学组成与其形成时诸强度变量(P总、P_(H2O)、T、fo_2等)之间的关系;闪石的化学组成与其岩石的化学组成之间的关系;某些元素在闪石和共生的铁镁矿物之间的分配等。因本文仅涉及前两个领域,故将这些方面的主要研究成果汇总于下: 1.区域变质岩的典型普通角闪石稳定于900～500℃之间,而阳起石是形成温度低于
Introduction The amphibole minerals are one of the major rock-forming minerals of igneous and metamorphic rocks. Since the 1960s, people have paid more and more attention to the amphibole minerals and conducted extensive research. These studies mainly explore the relationship between the chemical composition of amphibole and the intensity variables (P total, P H2O, T, fo 2, etc.) during its formation; the relationship between the chemical composition of amphibole and the chemical composition of its rock; The distribution of certain elements between amphiboles and symbiotic iron-magnesium minerals. The main research results of these aspects are summarized as follows: 1. The typical common hornblende of the regional metamorphic rocks is stable at 900-500 ℃, while the Yangjishi is formed at temperatures below
