dc.description.abstract Deep-sea surface sediments acquired by multiple corer from 59 stations in the Clarion-Clipperton fracture zone of the northeast equatorial Pacific, were examined to understand the correlation of mass physical properties and sedimentological processes. The seabed of the middle parts (8-12°N) in study area is mainly covered with biogenic siliceous sediment but also with pelagic red clays, especially in the northern parts (16-17°N). In the southern part (5-6°N) of which water depth is shallower than the carbonate compensation depth calcareous sediment prevail. It was found that mass physical properties such as grain size distribution, mean grain size, water content, specific grain density, wet bulk density, void ratio, and porosity of sediments were distinctly different according to their sediment types. These variations in mass physical properties of sediments are the combined results of the following factors: biogenic primary productivity of surface water, water depth, especially with respect to the carbonate compensation depth(CCD), sedimentation rate, input of wind-blown (eolian, lithogeneous) component, and the geochemical characteristics of the bottom water (for example, formation of authigenic clay minerals and dissolution of biogenic grains). -
