Geologists, more specifically mineralogists, identify minerals based on . A. Optical properties. B. Solid properties. C. Behavioral properties. D. Physical properties.

The minerals are mostly characterized by the Physical properties (D) which includes the hardness, lustre, density etc. The mineralogists check the detailed view of minerals by using high powered microscope.

The minerals are chemical compounds which are formed as a result of physical processes or geological processes. They mostly occur in crystalline form. For Example: Cacite, Sulfur, Quartz etc
