| 摘 要： | 通过对河南信阳龟山地区变余糜棱岩中不同产状的石榴石、黑云母及白云母等矿物的矿物学特征及其反映的变质作用温压条件研究，建立了区内变余糜棱岩热－构造演化的三阶段模式：（１）原岩的深部加热和抬升；（２）中深部走滑剪切和逆冲推覆；（３）浅表层脆性断裂和火山岩浆活动。

| Abstract: | This paper studies mineralogical features of some minerals such as garnet, biotite and muscovite etc. which exist as various occurrences and metamorphic conditions recorded by these minerals in blastomylonites in Guishan area, Xinyang. It is concluded that the thermotectonic evolution of the blastomylonites is divided into three stages as follows: the heating in depth and uplift of the parent rock of blastomylonites, deep ductile shearing and thrust napping, and the brittle fracturing and volcanic magmatism of the upper blanket. |
