The Pyroxene Mineral Group - Geology

The chemical properties of minerals mainly reflect the chemical properties of the atoms present in each. However, even here these properties depend on the way the atoms are bound in the mineral's crystal structure. Let us examine the property known as solubility — the ability of a mineral to dissolve in a liquid, like salt and water.
