Abstract: The Youjiang Basin in western Guangxi is a late Paleozoic-Mesozoic compound rift basin on the southwestern margin of Yangtze landmass. Under the regional extensional system, there appears the structural framework of extension-dominated alternate basin- platform and horst- graben style fault block structure. Structural- sedimentary event layers such as Permian sponge reefs, synsedimentary breccias belt and turbidite series are well developed, suggesting a marginal platform slope environment. In the interior or on the margin of the platform, there are parallel, micro- angle or overlap unconformities dominantly between upper Devonian and lower Carboniferous, between upper Carboniferous—lower Permian and middle Permian, between upper Permian and middle Permian, and between lower Triassic and middle Triassic strata, which respectively reflect four unconformable structural events of Liujiang orogeny, Qiangui epiorogenic event, Dongwu revolution, and Guixi movement. Based on the summarization of Late Paleozoic-Triassic extensive structural features of the Youjiang Basin, this study aims at providing useful reference for the investigation of the dynamics background and evolution mechanism of the Youjiang Basin, western Guangxi.
