Based on the data of Philippine shallow strata profile, combined with the sample data and borehole data in this area, this paper has a preliminary understanding of the shallow sediment characteristics of Kyushu-Palau Ridge and the West Philippine Basin and Parisi Vera Basin adjacent to the ridge. There are generally three wave impedance interfaces below the seabed, and the reflection characteristics of the shallow stratum profile are divided into four basic types. The causes of the profile characteristics are preliminarily discussed. It is believed that the sediment supply, tectonic activities, topography and hydrodynamic conditions play an important role in the deep-water sedimentation during the sedimentation process. Besides being influenced by the main control factors, most of them are also superimposed with the transformation effects of various factors in the later period. In this paper, the sedimentary characteristics and controlling factors of shallow strata in Philippine Sea are analyzed, which can provide useful reference for further study of deep shallow sediments in Philippine Sea.
