Olistostrome Review and Genetic Mechanism

The term olistostrome has been used worldwidely since it was coined by Flores(1956),which derived from the Greek words stroma and olistomail that means accumulation and to slide,and implies the concept of sediments having been accumulated by sliding.For the confusion in the usage of olistostrome, its original definition has later on been amended again and again by geologist.Here,we adopted Raymond’ definition.An olistostrome is a sedimentary slide deposit characterized by bodies of harder rock mixed and dispersed in a matrix.In this paper,we reviewed the evolution of the definition systemically and analysed the difference between olistostrome and m(?)lange,summarized the relations between olistostrome, slump,olistolith and debris flow,pointed out that olistostrome is transported and deposited
