Fig. 7From: Geophysical constraints on microbial biomass in subseafloor sediments and coal seams down to 2.5 km off Shimokita Peninsula, Japana Initial porosity vs. initial permeability for the core samples used for the permeability tests. b Initial permeability plotted against the modal pore size distribution. Dashed lines show regression curves. k: permeability (m2), Φ: porosity, and d: pore size (μm)Back to article page
