一、引言首先,让我们简略地复习一下变质作用的分类和命名。以地质背景为基础,变质作用一般可以分为两大类:一类是局部变质作用;另一类是区域变质作用。根据变质作用的主要因素,局部变质作用又可分为:(1)接触变质作用,是在岩浆侵入体边缘地带发生的变质作用;其主要因素是热力;其所形成的岩石的主要特征是没有片理构造。(2)压碎变质作用(cataclastic metamorphism),是限于在断层和逆冲断层及其附近发生的变质作用;其主要因素是压力,所以又常常被称为动力变质作用;其所形成的岩石的主要特征是
First, the introduction First of all, let us briefly review the metamorphism classification and naming. Based on the geological background, metamorphism generally can be divided into two categories: one is the local metamorphism; the other is the regional metamorphism. According to the main factors of metamorphism, the local metamorphism can be divided into: (1) contact metamorphism, which is metamorphism in marginal zone of magma intrusive body; the main factor is thermal energy; the main features of the rock formed are not Texture structure. (2) cataclastic metamorphism is limited to the metamorphism of faults and thrust faults and its vicinity; its main factor is stress, so it is often called dynamic metamorphism; and the rocks formed by it The main feature is
