Based on the comprehensive analysis of the types of sedimentary grain size in the studied region and the characteristics of organism, mineral and chemical compositions of the sediments, from the view-point of origin of the sediments, the sediments in the studied region are classified into four sedimentary types, namely, terrigenous detritus, biogenic-terri-genous, authigenous-terrigenous and volcanic-terrigenous (Fig. 1). Their characteristics, distributions and sedimentary regularities are approached in this paper.
