| 摘 要： | 本文根据华东南地区中新生代伸展构造的发育特点，划分出热隆伸展、裂陷伸展和重力伸展等３种伸展构造类型。其中，热隆伸展构造又可进一步划分为浅层次热隆伸展构造和深层次变质核杂岩构造两种亚类。不同类型伸展构造在构造样式、组合型式、运动方式、同构造期岩浆作用及形成作用特征等方面均存在明显的差异，文中分别对其进行了初步总结。

| Abstract: | From the geometry and formation features of Meso-Cenozoic extensional tectonics,threemajor types of extensional tectonics such as thermo-upwelling,taphrogenic and gravitationalextensional tectonics are distinguished in Southeastern China. Of them,the thermo-upwellingextensional tectonics can be subdivided into the shallow and deep ones,and the latter is commonly called metamorphic core complex. Different types of extensional tectonics are characterized by a series of evident variation in the aspects of structural forms,combination patterns, movement style and syntectonic magmatism,as well as formation processes. And theauthors have preliminarily summed up the general characteristics of different extensional tectonics respectively |
