mineral classification by chemical composition

mineral - Classification of minerals Britannica

2022-1-6  mineral - mineral - 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

The standardisation of mineral group hierarchies ...

However, if the classification is to adequately meet the needs of the CNMNC, it is proposed that the grouping be based on chemical composition and crystal structure, as these are the two essential components in the characterisation of a mineral species. Consequently, the simplified definition of a mineral group is:
