| 摘 要： | 核溪变质核杂岩构造位于华南的武夷山脉南段。该变质核杂岩构造由顺层塑性流变的内核、分划性右行斜落韧性变形的中间性、脆韧性右行滑落剪切变形的具薄皮构造特征的盖层组成“三层结构”。其间均为不同构造层的剥离断层（带）分划，各剥离层的上盘在下滑的同时右行走滑的特征也很明显，是一个具右行旋卷特征的变质核杂岩构造。该变质核杂岩构造于加里东期发育雏形，强烈隆升并定位于印支期，对燕山期及其以后的构造发展仍有一个控制作用。

| Abstract: | The structures of Taoxi metamorphic core complex,located in the southern sector of Wuyi Mountains in South China,are composed of the inner core of bedding plastic flows,the intermediate layer of right lateral slip ductile deformation and the thin skinned cap rock of right lateral slip shear deformation,which form a three ply structure.Among them they are the different kinds of stripped faults(zones),and the hanging sides of the stripped faults show the obvious sliding and dextral features,which is a structure of metamorphic core complex with right lateral convolutional characters.The structures of the metamorphic core complex formed in the embryonic form of Caledonian Movement,had a strong uplift and made an emplacement in Indo Chinese epoch.It had certain effects to control the development of Yanshanian structures or hereafter. |
