赣北前震旦纪构造变形特征及其动力学意义

Features of the pre-Sinian structural deformation in North Jiangxi and its dynamic significance

赣北存在近南北向(D1)、近东西向(D2)、北北西-北北东向(D3)三个世代的叠加褶皱。它们是华夏板块与扬子板块缓慢拼贴过程中应力向板内传递的结果,均形成于前震旦纪。从发生的时间来看,应与格林威尔造成山运动相当。

There exist three generations of superimposed folds extending along the longitudinal,latitudinal and NNWNNE direction in northern Jiangxi Province.They were formed one after another during the preSinian period and resulted from intraplate deformation related to slow collision between the Yangtze plate with the Cathaysia plate during the Grenville orogenic process.
