Density of Rocks and Soils
The bulk density is less than the grain density of the constituent mineral (or mineral assemblage), depending on the porosity. For example, sandstone (characteristically quartzose) has a typical dry bulk density of 2.0–2.6 g/cm 3, with a porosity that can vary from low to more than 30 percent.
Dry Bulk Density (DBD) of Rocks
The dry bulk density (DBD) is determined as dry mass of a rock (i.e. excluding natural moisture) per unit of actual in situ rock volume, including porosity. The commonly used DBD measurement methods are explained in this chapter, emphasising that methods differ depending on the material types, such as the competent non-porous …

The Density of Common Rocks and Minerals
Mineral and rock densities are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
