                                The vast majority of Earth's crust, over 90%, is composed of just one mineral group: the silicates. Mineralogy, the scientific study of minerals, classifies these naturally occurring inorganic solids primarily based on their chemical composition, which organizes the thousands of known mineral types into distinct classes. Understanding what are the four major groups of minerals provides a fundamental framework for comprehending geology.
