陆相湖盆深水砂质碎屑流成因机制与分布特征——以鄂尔多斯盆地为例

国外深水沉积发展了50年，从浊流定义的普遍应用，到今天对鲍马序列、约克扇等经典模式持否定态度，深水沉积研究经历了一个推陈出新的过程。目前国外流行的砂质碎屑流理论是经典浊流理论的部分否定与新发展。本研究阐述国外砂质碎屑流的概念、实验、鉴别特征、沉积模式等最新认识，以运用砂质碎屑流理论解释鄂尔多斯盆地湖盆中部厚砂岩的成因机制为例，揭示我国陆相湖盆中心坡折带砂体分布特征与形成机制，为开拓陆相勘探领域提供理论支撑。

Genetic Mechanism and Distribution of Sandy Debris Flows in Terrestrial Lacustrine Basin

The study of deep water sedimentation has developed fifty years.The misuse of term turbidite to deposits of deep water is common.Then the denial of Bouma sequence as the tubidite facies sequence and related fan depositional mode,the study on deep-water has undergone circle on cognition.The sandy debris theory is an innovation and negation to classical tubidity theory.The definition,experimentation,identification feature and sedimentation model were introduced in the passage.Applying the sandy debris theory ...
