摘要
赣西北地区双桥山群自上而下划分为修水组、安乐林组，共计１１个岩性段，其时代属中元古代蓟县纪，并以近东西向褶皱叠加早期近南北向褶皱为主要变形样式。就该群构造样式、地层序列、变质温压条件以及沉积环境等进行简要论述与综合分析，在此基础上对本区长期争议的“修水运动”作出了否定的回答。
The Shuangqiaoshan Group in northwestern Jiangxi, which is determined to be of Middle Proterozoic Jixianian age, can be divided into the Anlelin Formation and Xiushui Formation, including 11 lithological members. The major structural style of the group is marked by late E W trending folds superimposed on early N S trending folds. On the basis of a comprehensive analysis of the structural style, stratigraphical sequence, metamorphic temperatures and pressures and sedimentary environment, the authors give a negative answer to the long disputed 'Xiushui movement'.
