摘要
Autochthonous seismites of the Doushantuo Formation have been discovered in Xikou, Cili County in Hunan Province. Based on the profile measurement,detailed observations and description, combined with the analysis of the tectonic background, many typical seismites soft sedimentary deformation structures have been recognized. It suggests that in the Doushantuo Period,strong and frequency seismic activity occurred in study area,the nature and activity of earthquake fault varied with different phases. Tectonic activity which accelerates the organic carbon the oxidation is beneficial to development of organisms and also helpful to the phosphate accumulation.
