Printing Office) 56-57 https://doi.org/10.2973/dsdp.proc.5657.152.1980 1201-1205 Consolidation characteristics of marine sediments have been determined for several different geologic provinces (cf. Hamilton, 1959, 1964; Keller and Bennett, 1973; Trabant, 1977; and Shephard et al., 1978). These data have been used to enhance interpretation of sediment processes; to develop density, porosity, permeability, and depth relationships; to predict excess pore water pressures; as well as to determine the amount of sediment originally present before consolidation. With the inception of plate tectonic theory several geologic and geotechnical investigations have been performed to aid in delineating those processes associated with fore-arc slope development in various trench systems (cf. Lee et al., 1973; Carson et al., 1974; Seely et al., 1974; Bouma and Moore, 1975; Trabant et al., 1975; Moore and Karig, 1976; and Seely, 1977). Many of these studies have included consolidation testing. Lee et al. (1973) tested overconsolidated sediments below 300 meters at DSDP Site 181 (Aleutian Trench). Trabant et al. (1975) reported highly overconsolidated sediments below 397 meters at DSDP Site 298 (Nankai Trough). Carson (1977) discussed overconsolidated mudstones dredged from the Cascadia Basin. Each of these studies suggests the state of overconsolidation results from tectonically induced stress, deformation, and uplift. The ensuing discussion will describe consolidation test results from samples obtained in the Japan Trench province during DSDP Legs 56 and 57. 143.2317 145.5578 39.7355 40.6298 143.96871666666667 40.066916666666664 1977-10-01T00:00:00 1977-11-10T00:00:00 4.4 593.7 not specified DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 56-436 39.9327 145.5578 North Pacific/RIDGE -5240.0 1977-10-01T00:00:00 Leg56 Leg56 1977-09-11T00:00:00 1977-09-11 1977-10-07T00:00:00 1977-10-07 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Langseth, Marcus G Langseth, Marcus G von Huene, Roland von Huene, Roland Okada, H Okada, H Nasu, Noriyuki Nasu, Noriyuki doi:10.2973/dsdp.proc.5657.1980 This leg comprised 24 days in the shipyard, 1 day in port calls, 36 days cruising and 19 days on site.
