Fluorescent Minerals from Southern Arizona

The fluorescence is the result of minor impurities in the minerals slightly altering chemical bonds in the crystal structures of the minerals. The Paleozoic limestone host rock was heated and brecciated as a result of the nearby intrusion of magma. Tremolite and muscovite replaced silty layers in the limestone.

The Density of Common Rocks and Minerals

Jan 23, 2020· 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, can have densities ...

Dolostone (Limestone)

The principal mineral of limestone is calcite (CaCO3), a form of calcium carbonate. Dolostone is quite similar to limestone, but is composed mostly of the mineral dolomite (CaMg(CO3)2). Both are sedimentary rocks that occur as thin to massive beds of fine- to coarse-grained rock.
