· 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).).

Igneous rock is formed when magma, which is liquid molten rock, cools or sets, solidifying into rock and rock formations. As this magma, or molten rock emerges to the surface, it experiences a change in temperature and pressure, which forces it to cool and crystallize, forming rock.

Rock-forming mineral, any mineral that shapes igneous, sedimentary or metamorphic rocks and that acts as an intimate part of rock-making procedures, typically or exclusively. Those minerals, on the other hand, have a restricted mode of incidence or are created by more uncommon procedures such as metal ores, vein minerals, and cavity fillings.
