摘要: 滁河断裂从古生代以来记录了下扬子地区的动力学特征。该断裂震旦纪—志留纪是滁县—全椒深水盆地与巢县—含山浅水盆地的分界线 ;晚泥盆世—中三叠世其北侧未见沉积 , 南侧表现出由于扬子板块向北俯冲而导致的陆内拉张断陷 ;晚三叠世时成为大别—胶南造山带南侧前陆冲断褶带中一条重要的逆冲断层 , 随后卷入郯庐断裂系的左行走滑剪切 ;晚白垩世—早第三纪时表现为垒堑构造的调整边界 , 控制着滁全红色盆地的发展。新生代以来再次表现为逆冲推覆特征。Abstract: The Chuhe fault has recorded the dynamic features of the lower Yangtze region since the Paleozoic. It was the boundary between the Chuxian Quanjiao deep water basin and the Chaoxian Hanshan shallow water basin from the Sinian to Silurian. From the Late Devonian to Middle Triassic no deposition occurred on its northern side, whereas its southern side was marked by the occurrence of an intracontinental extensional fault depression resulting from northward subduction of the Yangtze plate. In the Late Triassic it became an important overthrust fault in the foreland thrust fold zone on the southern side of the Dabie Jiaonan orogenic belt, and then it was involved into sinistral strike slip shear of the Tancheng Lujiang fault system. During the Late Cretaceous to Paleogene it was manifested as an adjusting boundary of the horst and graben structures, controlling the development of the Chuxian Quanjiao red basin. Since the Cenozoic it becomes an overthrust again.
