The Density of Common Rocks and Minerals ThoughtCo

Jan 23, 2020· Mineral Densities . As a general rule, non-metallic minerals have low densities while metallic minerals have high densities. Most of the major rock-forming minerals in the Earth's crust, like quartz, feldspar, and calcite, have very similar densities (around 2.6 to 3.0 g/cm 3). Some of the heaviest metallic minerals, like iridium and platinum
