Fig. 3From: Geophysical constraints on microbial biomass in subseafloor sediments and coal seams down to 2.5 km off Shimokita Peninsula, JapanExamples of pore size distribution for core samples at Site C0020. Mean (a), modal (b), and median (c) pore size distributions are plotted in the same figures: a silty clay at 177.7 mbsf, b sandstone at 1490.8 mbsf, c shale at 1610.8 mbsf, d coal at 1920 mbsf, e well-cemented sandstone at 1975.8 mbsf, and f siltstone at 2201.3 mbsfBack to article page
