glaucophane greenschist facies

The discovery of glaucophane greenschist facies rock mass in Lianyungang , northern Jiangsu

苏北连云港地区蓝闪绿片岩相岩块的发现

The metamorphism of the Susong Complex is intermediate between that of the southern glaucophane greenschist facies belt and that of the northern eclogite facies belt , three of which represent the products of the different subduction depths of the Yangtze plate under the North China plate .

宿松杂岩的变质条件介于其南部的蓝闪绿片岩相和北部的榴辉岩相之间，三者是扬子板块向华北板块之下俯冲到不同深度的产物。

The whole process of metamorphism can be divided into three parts : spilitization metamorphism of mid low pressure in extension situation → regional metamorphism of mid high pressure in compressional structure → metamorphism of high pressure glaucophane greenschist facies in partial areas .

变质作用过程可分为三个阶段：拉张环境中的中低压细碧岩化变质作用→挤压造山环境的中高压区域变质作用→局部地区的高压蓝闪石绿片岩相变质作用。
