| 摘 要： | 对我国区调填图工作历程与现状进行概述基础上,对造山带的主要特点,构造岩片的含义,构造岩片填图法的理论依据、基本工作程序及实施要点作了论述;对造山带中常见的"混杂岩"、强烈构造变形变质的层状变质岩、穹隆状变质地质体的主要特征、产出的地质构造条件及其成因机制等进行了较全面总结和分析;建议将"混杂岩"和"穹隆状变质地质体"分别划分为蛇绿混杂岩、火山混杂岩、滑积混杂岩、构造混杂岩和变质核杂岩、花岗岩底辟穹隆(岩浆核杂岩)、片麻岩穹隆、构造穹隆等类型。

| Abstract: | This paper deals with history and present situation of regional geological mapping,definition of tectonic slice,theoretical basis and working procedure of tectonic slice mapping method in China and makes an approach to major features,occurrence and genetic mechanism of orogenic zone,mélange,strong deformed layered metamorphic rock,dome-shaped metamorphic terrain.The suggestions on genetic classification for the mélange and dome-shaped metamorphic terrain are made in this paper,i.e.the mélange may be divided into 4 types such as ophiolitic mélange,volcanic mélange,slump mélange and tectonic mélange and the dome-shaped metamorphic terrain may be divided into 4 types such as metamorphic core complex,magmatic core complex,gneiss dome and structure dome. |
