Different mineral forms under different conditions and under different geological settings. These minerals combine with one another giving rise to the formation of rocks.
They are characterized by the presence of both physical as well as chemical properties.
Example of some minerals includes, Calcite, Fluorite, Quartz, and Feldspar.
