The Composition of Earth: Rocks and Minerals - EOLSS

2020-8-18  The study of minerals and their behavior is called “mineralogy.” “Petrology” is the study of rocks in terms of their mineralogy, composition, textures, formation, and associations, whereas “petrography” is the science of describing rocks. There are some 4000 species of minerals, and new ones are continually being discovered. However ...
