Abstract

The authors investigated the sedimentary environments  and their hydrodynamic processes in the Qinzhou Bay,
based on the data of surface sediment samples collected in 2008  in combination with sediment texture, topography, and hy-
drodynamics of the bay. The results indicate that transversal distributions of surface sediments in the outer bay are from coarse
to fine particle size, and the degree of the sort is from good to poor level. For the longitudinal distribution of surface sediments,
there is a large percentage of sand at the underwater slope that is shallower than 5 m; however, slit and clay predominate at the
underwater slope that is deeper than 5 m. According to the differences in hydrodynamic, morphologic features, and sediment
sources, the outer bay can be divided into three main sedimentary zones.

Key words： grain size; hydrodynamics; deposition district; Qinzhou Bay
