Quartz Crystal Mineralogy


Mineralogy is a scientific field that studies all aspects of minerals. This includes the physical properties, chemical composition, internal crystal structure, occurrence, and distribution in nature. It also seeks to understand the origins of minerals in terms of the physicochemical conditions that led to their formation. James D. Dana is a key figure in this field.
