Summary

We used CRS consolidation experiments and grain-size analyses to define the bulk geotechnical properties and grain-size distribution of specimens from 0 to 100 mbsf at Sites C0004 and C0006–C0008, which were drilled and sampled during Expedition 316. Interpreted in situ permeability is generally <10^–14 m² and does not exhibit depth or grain-size trends. Compression indexes range from 0.15 to 0.9 and also do not show any strong trends. The overconsolidation ratio decreases downhole, and most samples had an OCR >1. Grain-size distributions documented that the shallow sections of these sites are dominated by silt- and/or clay-sized particles with median grain sizes ranging from 0.003 to 0.026 mm, with the exception of one sand-rich specimen.
