摘要: 扬子（地台）东南缘，自江西乐平向北一直缺少上、下古生界之间角度不整合接触关系的报道。本文通过新发现的一系列加里东期角度不整合接触关系，结合下古生界中2期强烈褶皱的变形分析，论证了扬子东南缘北段（浙皖赣相邻区）存在加里东期褶皱。

Abstract: Unconformity between the Upper and Lower Paleozoic is absent from Leping of Jiangxi all the way upward, on the southeastern margin of the Yangtze platform. According to a number of Caledonian unconformities discovered recently, combined with an analysis of two phases of strong fold deformation in the Lower Paleozoic, this paper demonstrates that Caledonian folds occur in the northern segment (Zhejiang-Anhui-Jiangxi border region) of the southeastern margin of the Yangtze platform.
