Abstract:
Constant-rate-of-strain consolidation experiments and grain-size analyses are used to characterize the flow and deformation behavior and grain-size distribution of vertically and horizontally oriented specimens from 0 to 100 meters below seafloor at Integrated Ocean Drilling Program Expedition 316 Sites C0004 and C0006-C0008. Interpreted in situ permeability was generally <10 (super 14) m (super 2) , but values ranged from 4.6X10 (super 14) m (super 2) to 1.1X10 (super 16) m (super 2) and do not exhibit any definitive trends with depth or grain size. Compression indexes, defining stress-strain behavior during normal consolidation, ranged from 0.15 to 0.9. The overconsolidation ratio (OCR) of vertically oriented specimens, which relates the in situ effective stress to the hydrostatic effective vertical stress, decreased downhole, and most samples had an OCR >1. Grain-size characterization by settling analysis documented that these shallow sediments are dominated by silt and/or clay, with median grain sizes ranging from 0.003 to 0.026 mm, excluding one sand-rich specimen.
