Abstract
Deep-sea surface sediments acquired by multiple corer from 69 stations in the Clarion-Clipperton fracture zone of the northeast equatorial Pacific, were analyzed for shear strength properties to understand sedimentological process. The pelagic red clay from northern part of study area shows low average shear strength (4.4 kPa), while the siliceous sediment from middle area shows high (6.3 kPa). The calcareous sediment from southern area shows very low average shear strength (3.4 kPa), and transitional sediment between middle and southern area shows intermediate value (3.8 kPa) between siliceous and calcareous sediment. The depth profiles of average shear strength of pelagic red clay show gradual increment with depth due to decrease of water content with depth by general consolidation process. On the other, abrupt increment of average shear strength with depth in siliceous sediment is related to sedimentary hiatus. The very low shear strength in calcareous sediment is linked to very high sedimentation rate of southern area compared with other study area.key words: shear strength, northeast Pacific, deep-sea sediment
