Figure F39. Cross-plot of wet bulk density and porosity from section samples, Hole M0028A. Diagonal line = mixing line between rock (zero porosity and density of 2.7 g/cm3) and saltwater (100% porosity and density of 1.024 g/cm3). Note how glauconite lithologies consistently fall to the right of the mixing line with greater density, probably because glauconite has a density up to 2.9 g/cm3.
