Rock Identification Chart . i The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). {\displaystyle \rho _{\rm {calcite}}=2.71} and . �.��2l��.M�nQ��3Ӈ_X0��E0�DQ��S�� Min Ss 2.00–2.60 g/cm: 2.35 g/cm: 2.68 g/cm: 41% 20% 5% Ls 2.20–2.75 2.55 2.71 30 10 0 Sh 1.90–2.70 2.40 2.72 48 19 0 being in g/cm and = or 0.23 when is in m/s or ft/s, respectively. = / Interestingly, peridotite are the rocksthat naturally occurring diamonds are found in.
