摘要
In order to understand the sedimentary characteristics and distribution of the turbidites developed at the gentle slope of depression basins, the upper Cretaceous Qing1&2 members at the western slope of South Songliao basin is chosen as the research object. Its sedimentary facies and distribution are studied by investigating the cores, logging data and seismic interpretation. Compared with rift basins, the scale of fluxoturbidites developed in depression basins is relatively smaller and the grain size of it is finer because the fault activity of gentle slope in depression basin is very weak and its slope with lower angle.
