What is Mineralogy?

Mineralogy is a subject of Geology that deals with the study of Minerals. The rocks are generally made up of heterogeneous materials, so it's difficult to study the structure and composition of the rocks without establishing homogeneous components of the rocks. The minerals are such homogeneous components that contain uniform physical and chemical properties. We can study the origin and properties of rocks with the help of minerals.

The rocks that are composed of a single mineral are called monomineralic rocks, and the rocks that are composed of multiple minerals are called polymineralic rocks. Crystallography is the study of crystal structure of the minerals. It is generally taught as a separate subject in colleges. Optical Mineralogy is the study of optical properties of the minerals under a microscope. The identification of minerals is difficult in comparison with rocks. So, sometimes an in-depth study is required. The mineralogy is also important to establish the economic viability of the minerals. The internal fractures and chemical composition are generally used in the assessment of the grade of the minerals. However, the mineralogy is only limited to the exploration stage in mining and petroleum industries. They rarely look into the mineralogy as they work on large scale deposits.
