Density

Introduction. Unlike other physical properties, the densities of the commonest rock forming minerals are remarkably close together. The actual densities of pure, dry, geologic materials vary from 880 kg/m 3 for ice (and almost 0 kg/m 3 for air) to over 8000 kg/m 3 for some rare minerals. Rocks are generally between 1600 kg/m 3 (sediments) and 3500 kg/m 3 (gabbro).

Understanding porosity and density

Density is defined as the mass per volume. In rocks, it is a function of the densities of the individual grains, the porosity, and the fluid filling the pores. There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples.
