### Specific Gravity and Bulk Density | SGS

“Specific gravity” is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock’s “bulk density” arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.
