Consolidation and Pore Fluid Pressure of Ursa Sediments, Deepwater Gulf

15 We conducted uniaxial compression tests on whole core samples from the Ursa 16 Basin, deepwater Gulf of Mexico, to obtain the consolidation properties of mudstones. 17 We showed that specific volume (v = 1+e) (where e is void ratio) declines as an 18 exponential function of effective stress and we used this relationship to successfully 19 predict in-situ pressure from void ratio at IODP Site...

12. Physical Properties and Consolidation of the Calcareous Sediments of Broken and Ninetyeast Ridges

Calcareous sediments cored at Broken and Ninetyeast ridges in the eastern Indian Ocean reveal the transitions from calcareous ooze to chalk and from chalk to limestone. Based on downhole porosity trends and laboratory mechanical consolidation tests, the compaction and lithification of these sedimentary sections occur at stratigraphically shallower depths than comparable marine calcareous sectio...

laboratory assessment of the electro-osmotic consolidation technique for urmia lake sediments

the electro-osmotic consolidation is a method to improve geotechnical properties of soft clayey soils. the feasibility of electro–osmotically induced consolidation can be examined through the soil coefficient of electro–osmotic permeability (ke) and the electro–osmotic coefficient of water transport (ki). using an electro-osmotic testing cell, ke and ki parameters were measured in urmia lake we...

Burial Consolidation Processes of Deep-sea Sediments: an Example of Core Sediments Collected from the Labrador Sea in the Northwest Atlantic

Progressive change of microfabrics of deep-sea sediments during early diagenesis was analyzed using two drill cores collected from the Sites U1305 and U1306 of the Integrated Ocean Drilling Program Expedition 303 in the Labrador Sea in the northwest Atlantic Ocean. Microfabrics were analyzed by scanning electron microscope and deduced from anisotropy of magnetic susceptibility. DiŠerent microfa...
