Definition
"Prof Hugo Strunz introduced a chemical-structural classification of the entire domain of minerals (Mineralogische Tabellen, 1941), followed by A.S.Povarennykh with a modified classification (1966 in Russian, 1972 in English). The chemical-structural classification of H. Strunz has gone through a number of editions, and is currently in the process of being refined in the light of recent crystal-structure determinations. In the current system, minerals are divided into 10 major compositional classes (1) elements , 2) sulfides , 3) halides , 4) oxides , 5) nitrates, carbonates , 6) borates , 7) sulfates , 8) phosphates , 9) silicates , 10) organic compounds ) which are subdivided into divisions, families and groups on the basis of chemical composition and crystal structure."
