Cambrian sequences in Southeast margin of Yangtze Platform are represented by various types of \"carbonate gravity flow deposits\". Such cases have been viewed as the proxies of \"platform margin slope facies\". Sedimentary characteristics from the \"Huaqiao Formation\" at Wangcun section, Northwestern Hunan where is the \"GSSP\" of the \"Guzhangian Stage\" were considered to be \"Calciturbidites\" lithologically. The present study illustrates that they are not typical \"Calciturbidites\", but normal carbonate sediments from the low-energy depositional environments with depth below the wave base. Section A of the \"tipical turbidite sequence\",which were considered to develop in the Huaqiao Formation, is actually composed of numerous limestone lens and lumps formed in diagenesis compaction. Meanwhile, neither grading sequence grain stone nor burthen structures could be observed in the outcrop. \"Undulate bedding\" developed in section B of the \"turbidite sequence\" is actually deformed Horizontal bedding and hummocky cross bedding, which is probably storm-generated. The observations, combined with the discover of two beds of oolitic limestone from the lower member of the \"Huaqiao Formation\", indicate a deep-water environment that is intermittently effected by oscillatory currents. By comparison with sedimentary records in adjacent regions, the findings suggest a new understanding to palaeogeography in corresponding period: a carbonate shelf (ramp) without typical platform-edge slope developed in northwestern Hunan.
