Kaolishan Formation of Early Carboniferous stage Datangian is outcropped in Kaolishan of Jurong�� Jiangsu Province�� The Kaolishan Formation mainly developed in mudstone��siliceous and sandstone�� The litho associations show that the Kaolishan Formation is composed of four lithological members including: ��siltstone���� shale���� alternating siliceous and shale and ��sandstone�� The main sedimentary types of Kaolishan Formation are coastal��shallow marine-bathyal and delta�� Four subfacies including coastal lagoon��deep water shelf��delta front and delta plain��and seven micro-facies including lagoon mud��deep water mud and silicious��inter-bay��underwater channel��inter-lobe��interdistributary channel and interchannel; are further identified��which are characterized by deep water silicious in this area�� Based on the ptrology and lithofacies change��the Kaolishan Formation can be regarded as an integral sequence in third order��including LST��TST and HST�� The analysis of relative sea level change indicates that there was a third rank of sea level change at duration of the development of the Kaolishan Formation�� which controlled the forming of this sequence�� Based on the tectonic depositional analysis��the Kaolishan Formation developed under the setting of compressional retro-arc foreland��
