Based on field observation on the Jinpen Section and Liushaguan Section and laboratory analysis, sedimentary structures of storm deposit are present in the succession, excluding hummocky cross-stratification. Particularly, the lag-suspension deposit couple is evident, winnowed coarse lag deposits occur in the below with an overlying fine laminated bed. Three types of storm deposit sequences with different vertical stacking patterns were identified. In summary, the storm deposits in Zhenyuan is attributed to tidal flat storm deposit, that enrich the style of storm deposits of Qingxudong Formation, Early Cambrian, in eastern Guizhou Province and western Hunan Province. The distribution pattern of storm deposit of Qingxudong Formation, in eastern Guizhou and western Hunan Province was preliminarily summarized based on the previous work and this paper. The discovery of storm deposits reflects indirectly the study area should be located in the low latitudes near the equator during the Early Cambrian.
