Sediment permeability at the Nankai accretionary prism, Site 808

Abstract

Results of over 60 permeability measurements made on subsamples of Site 808 cores reveal coefficients of permeability ranging from 10-5 to 10-10 cm/s (10-14 to 10-19 m2) in horizontal and vertical directions. The generally low permeability of sediments at the depth of the decollement must influence the stress-strain behavior of this major structural horizon. -from Authors
