| 摘 要： | 扬子地台东南缘的花垣李梅地区,早寒武世晚期清虚洞组钙质风暴岩分布广泛,表现为层数众多,剖面类型丰富,识别标志清楚,颇具特色。风暴作用强度和侵蚀力按地层层序自下而上有由弱到强的规律性变化,与本区清虚洞期陆棚浅滩化演变过程相对应。早寒武世晚期的风暴事件与本区岩相、岩性的分布,均有密切联系。

| Abstract: | The Early Cambrian calcareous tempestite distributed extensively in Qingxudong Formation of Limei area, Huayuan county of southeastern margin of Yangtze platform where many layers of tempestite have been found with various types of profile and clear identification indicators. The storm intensity and erosion force changed regularily from weak to strong according to the stratigraphic sequence from bottom to top corresponding to the shallowing-upward process of Qingxudongian shelf. The late Early Cambrian storm event is in close connection with the sedimentary facies, lithology in this area. |
