Permeability of six samples from Integrated Ocean Drilling Program (IODP) Sites C0001 and C0006 was measured in a triaxial cell under effective hydrostatic confining pressure from 1 to 30 MPa. Sample depths range from 225 to 448 meters below seafloor (mbsf) for Site C0001 and from 201 to 564 mbsf for Site C0006. Our results indicate that the initial permeability at 1 MPa of effective confining pressure ranges from 4.6X10 (super -18) to 1.8X10 (super -19) m (super 2) depending on depth. Permeability decreases with increasing depth, which also corresponds to a decrease of porosity from 62% to 43%. The permeability versus depth trend is similar for both sites. When the effective confining pressure is increased from 1 to 30 MPa, the permeability decreases for all samples. However, this trend shows some variability, indicating a finer microstructural control depending on the lithologic origin of the sample.
