Figure F7. Distribution and lithologic variation of porosity in discrete core samples with comparison of cuttings, Site C0020. Porosity of sandstone and siltstone gradually decreased with depth, though carbonate cemented rocks deviate from the consolidation curve with remarkably low porosity. Higher porosity and slower reduction in porosity with depth is observed in cuttings samples. Discrete core samples can be more representative for in situ porosity than porosity of cuttings.
