砂质碎屑流和底流改造——部分传统浊积岩成因新解

SANDY DEBRIS FLOW AND BOTTOM CURRENT REWORKING: A NEW INTERPRETATION OF THE FORMATION OF A PART OF TRADITIONAL TURBIDITE

以鲍马层序为代表的古典浊积岩，在地质学界曾广泛流行。近年来的研究表明，真正的浊积岩是很少发生的。由于浊流和碎屑流具有不同的流变学特点，人们对部分传统浊积岩提出了砂质碎屑流和底流改造成因及其鉴别标志，并对传统海底浊积扇模式在进行重新研究的基础上提出了海底碎屑流模式。

The classical turbidite with Bouma sequence,was once popular in the geology field However,the recent study shows that the real turbidite is practically rare Considering the differences of the rheology between turbidity and debris flow,people suggest a new interpretation of the sandy debris flow and bottom current reworking of the formation of a part of the traditional turbidite and its diagnostic features,and furtherly,present a depositional model of debris flows using as a substitute for the obsolete submarine fan models
