Abstract
According to the comprehensive analysis of core observation,logging data and regional geological backgroud,turbidite sedimentary characteristics of fuxian Area in southern Ordos Basin were discussed.It is considered that the turbidite deposition is mainly developed in Chang 6 and Chang 7 strata,the type of turbidite deposition is delta slump.It is divided into outer fan and middle fan,inner fan is not developed,the lake slump turbidite fan system is discussed.The corresponding depositional mode or pattern is established.Furthermore,its significance of oil and gas genesis is analyzed.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
