Abstract: The third member of Shahejie formation of Paleogene (Es3) in Huimin sag of Shandong province is divided into three middle base level cycles and one base level rising semi-cycle, which includes six types of sedimentary facies such as delta, fan delta, turbidite fan, turbidite channel, slump turbidite and lacustrine facies. These sedimentary facies could be assembled into such five depositional systems as fluvial-delta system, delta-(slump) turbidite system, fan delta system, fan delta-slump turbidite system and near-shore submarine fan system. Taking the middle base level cycle (C3) as an example, the horizontal distributions of these depositional systems are analyzed.

Key words: Huimin sag, Shahejie formation, base-level cycle, depositional system
