Mineral - Wikipedia
In 315 BCE, Theophrastus presented his classification of minerals in his treatise On Stones. His classification was influenced by the ideas of his teachers Plato and Aristotle. Theophrastus classified minerals as stones, earths or metals. Georgius Agricola's classification of minerals in his book De Natura Fossilium, published in 1546, divided minerals into three types of substance: simple (sto

Classification of minerals. Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition.Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides).Several reasons justify use of this criterion as the distinguishing factor at the
