Based on field hydrographic surveys and sediment data analysis,the influences of water and sediment characteristics,component of deposited material and variation of salinity on depositional rate of sediment in the area is discussed and sediment source as well.

Estimation of bulk diffusion coefficients in nearshore sandy sediments by resistivity method;

Study on the laboratory compression test of the Tertiary argillaceous sediments in the upstream of Yellow River under super-high pressure;

To study OM enrichment mechanism and interaction of organic matter with inorganic minerals in argillaceous sediments, we employed size grading, microscope, X-ray diffraction (XRD) and gas chromatography (GC) to obtain information on OM and minerals.

It is indicated that ferrimagnetic minerals dominate the magnetic properties of surface siliceous sediments in the Clarion-Clipperton (C—C) zone, northeastern equatorial Pacific.
