The effect of density on porosity follows a mixing law. The porosity,, is the fractional pore volume of a rock. The total mass of a volume of rock V T is made up of the mass of the pore fluid, of density f, plus the mass of the matrix minerals of density ma The density measured is the bulk density b. The total mass then becomes:

Density. Clays generally have density between 1.6 to 2.6 g/cc. The clay content of a soil has a significant effect on its density. Salt is of particular interest in sedimentary rocks because it has a low density (2.2 g/cc), but has a fairly high bulk modulus giving it a relatively high seismic velocity (velocity of
