Abstract: The Zhejiang-Anhui-Jiangxi border region was affected by the South China Caledonian tectonic event in the Caledonian period. As a result, the pre-Sinian basement and earliest Paleozoic cover were strongly uplifted and folded and the Early-Mid Carboniferous strata in the Zhejiang-Anhui-Jiangxi border region directly overlies the Mesoproterozoic low-grade metamorphic series and the Middle Carboniferous in the Qingliangfeng area at the eastern end of the region overlies the Upper Cambrian, but no evidence of Caledonian magmatism is found. In addition, the Sinian-Early Silurian covers on the southern and eastern sides of the craton are detached toward the two sides and overturned together with the basement near the contact zone to form overturned folds. The covers on the northern side are detached toward the north to form slip-superposed folds and the Linxi and Lantian relict synclinal basins. The Indosinian and Yanshanian events significantly modified the Caledonian tectonic features and finally formed the tectonic framework that in the main continues to the present.
