广西丹池(南丹—河池)盆地内部在上泥盆统弗拉斯阶与法门阶分界线上普遍发育事件沉积作用,自台地边缘到台内裂陷槽盆地事件沉积分为碎屑流、颗粒流和浊流,沉积岩石分别为砾屑灰岩、含砾砂屑灰岩、递变层砂屑灰岩等。该事件沉积具有等时性、成因相关性和广布性。事件沉积绝大部分位于linguiformis带和triangularis带之间。这些事件沉积可以和广西横县六景、桂林杨堤、德保都安、武宣南峒、象州香田、崇左那艺、上林云攀以及比利时的Hony剖面、美国内华达的Devil sGate剖面、摩洛哥的Atrous剖面、南乌拉尔、俄罗斯西伯利亚东北部的Fore-Kolyma、波兰—摩拉维亚盆地南部(Holy Cross山脉,Cracow和Brno地区)法门阶底部的浊积岩和角砾岩对比。如此广泛的全球性分布的等时性的事件沉积可以和巨大的外行星撞击地球而引起的全球性海啸相联系。
In Danchi (Nandan-Hechi) Basin, Guangxi, the event sedimentation was generally developed on the boundary between Flusian and Famenian stages of the Upper Devonian. The sedimentary events from the margin of the platform to the rift basin in Taiwan were divided into debris flow, Particle flow and turbidity flow, sedimentary rocks are respectively gravel limestone, gravel sandy limestone, graded limestone sandstone and so on. The deposition of this event is isochronous, causative and broad. The majority of event deposits lie between the linguiformis and triangularis zones. These events can be deposited in conjunction with the six scenic spots in Hengxian County of Guangxi, Yangdi Guilin, Deguodian’an, Wuxuan Nanxun, Xiangzhou Xiangtian, Chongzuo Nanyi, Shanglin Yunpan and the Hony section of Belgium, the Devil sGate section of Nevada, the Atrous section, South Urals, Fore-Kolyma in northeastern Siberia, Russia, and turbidite and breccia at the bottom of Famenn, Poland-Southern Moravian Basin (Holy Cross Mountains, Cracow and Brno). The deposition of such a wide range of globally distributed isochronous events can be linked to the global tsunami caused by the huge external planets hitting the Earth.
