Mineralogy is a branch of Geology deals with the study of minerals. The subject of mineralogy attempts to study the various aspects of minerals. Mineralogy is a subset of geology specializing in the scientific study of chemistry, crystal structure, and physical (including optical) properties of minerals. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. The study of mineralogy includes the study of Physical characters (Physical Mineralogy), Chemical characters (Chemical Mineralogy), Optical properties (Optical Mineralogy), Mode of occurrence and the formation of minerals (X-Ray Mineralogy). Due to the advancement of knowledge and improvement in techniques, Mineralogy also includes applied aspects. A mineral can be defined as a naturally occurring, homogeneous solid, inorganically formed having a definite chemical composition and ordered atomic arrangement. According to this definition, a mineral will have the following characters: It must have formed naturally; Minerals prepared in the laboratory by artificial method cannot be called minerals in the true sense. Every mineral will be uniform or homogenous in composition. It must be a solid, but the recent (latest) trend is to include coal and petroleum under minerals. But majority of the minerals are solids. Inorganic processes form the minerals. Very rarely formation of certain minerals like Quartz, calcite etc. has been observed in certain parts of the human body, Even though such substances in the body possesses the characters of minerals they cannot be called minerals. Every mineral will have a definite chemical composition. For example - Quartz (SiO2), Graphite (C) Calcite (CaCO3) every mineral is characterized by a definite internal atomic arrangement of an atom.
