Halite hardness
Most common minerals, such as quartz, feldspar, calcite, amphibole, and mica, are of average density (2.6 to 3.0 g/cm 3 ), and it would be difficult to tell them apart on the basis of their density. On the other hand, many of the metallic minerals, such as pyrite, hematite, and magnetite, have densities over 5 g/cm 3.
Salt (halite) Halite (NaCl) is a soft, light colored or clear mineral that forms cubic crystals. Vast beds of salt evaporated from shallow seas that covered Ohio at times during the Silurian Period.
