摘要: 惠民凹陷古近系沙河街组三段(Es3)由3个完整的中期基准面旋回和1个基准面上升半旋回构成。沙三段发育三角洲、扇三角洲、水下浊积扇、浊积水道、滑塌浊积岩以及湖泊相6种沉积相类型。以基准面升降半旋回为单元,上述6种沉积相在平面上可以组合成5种沉积体系:河流-三角洲沉积体系、三角洲-(滑塌)浊积扇体系、扇三角洲沉积体系、扇三角洲-滑塌浊积扇沉积体系、近岸水下扇沉积体系。以中期基准面旋回C3为例分析了沉积体系的平面分布特征。

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
