Specific Gravity and Bulk Density | SGS Canada

"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.

A methodology for density determination from core …

imagery, combined with mineral density has potential to meet this need. In practice, the uncertainties in mineral abundance and density often render the bulk density from core imagery alone unreliable. However, if mineral grades estimated from imagery correlate well with assays, then greater confidence in prediction of density is justified.
