Abstract: The lower part of the late Permian in the Guodikeag Area, Caiwopu depression is divided from bottom to top into Wulnbo formation and Jinjinzigou formation which belong to marine and continental interfacies deposit of sand and clay. Edgewise pebbly conglomerate (wormkalk) of 2 meters thick can be seep in the Wulabo formation ,while migmatite composed with land sand, endoclastic, oolite and sandstone with hilllock-like crossed bedding are distributed in the Jinjinzigou formation, They are storm event beds formed under actions of strong water flow and waves and with characteristic primary depositional building such as hilllock-like bedding ,Kinneya structure. This paper presents a description of the background deposition of this storm event beds, suggesting its genetic environment. ecological distribution and implication of petroleum feneration and accumulation.
