华夏系构造以北东向的折皱带为特征,在我国东部分布相当广泛。但在华北东部和华东北部的辽、鲁、苏、皖等地区是否存在着华夏系构造?则是一个长期未能得以确立的问题。近年来,围绕郯城-庐江断裂带(以下简称郯庐断裂带)是否有“巨大平移”的争论, 使问题愈加明朗,促进了我们对这两方面的相互关系的研究。 The Cathaysian system is characterized by the north-eastern fold belt, which is widely distributed in eastern China. However, is there a problem with the establishment of the Huaxia system in the Liao, Lu, Su and Wan areas in eastern North China and northeast China? In recent years, the controversy surrounding the Tancheng-Lujiang fault zone (hereinafter referred to as the Tan-Lu fault zone) has made the issue more clear and has promoted our research on the interrelationship between these two aspects.
