上扬子地台基底演化探讨

A discussion on the basement evolution of upper YANGZI PLATFORM

康定群的地质特征及其在扬子地台基底演化中的意义

The characteristics of the Kangding group and its implication for the evolution of the Yangtze platform basement

研究表明四川盆地的形成演化曾经历了中-晚元古代扬子地台基底形成阶段；

It has undergone a complicated development process divided into four stages as follows : ① the crystal basement of Yangtzc platform form stage since Meso-Proterozonic-Neo-Proterozonic ;

将基底结构分为两种类型，即种马场断裂以南为塔里木地台型基底，以北为海西期褶皱基底。

The basement is of Tarim platform to the south of Zhongmachang fault and of Hercynian fold to the north .

对河口群的深入研究，有助于深化认识扬子地台西缘基底结构的特点及演化过程。

Advanced study of Hekou Group would have important implications for understanding of the feature and evolution of the basement structure of Western Margin of Yangtze Terrane .

辽宁省位于华北地台北缘，其地质构造演化主要经历了地台基底形成（Ar－Pt1）、盖层沉积（Pt2－T2）、地台活化（T3以后）三个阶段。

Liaoning province is located on the northern borderland of North China Platform , which has mainly experienced three stages : the forming of platform basement ( Ar-Pt 1 ), the depositing of cover ( Pt 2-T 2 ), and the activizing of platform ( after T 3 ) .
