    Use of old mineral names is also discontinued, for example when a name is no longer considered valid. Therefore, a list of recognised mineral species is never complete. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.

    Epidotes are built around the structure [(SiO 4)(Si 2 O 7)] 10− structure; for example, the mineral species epidote has calcium, aluminium, and ferric iron to charge balance: Ca 2 Al 2 (Fe 3+, Al)(SiO 4)(Si 2 O 7)O(OH). The presence of iron as Fe 3+ and Fe 2+ helps buffer oxygen fugacity, which in turn is a significant factor in petrogenesis ...

    The formula of the admixture of the three most common endmembers is written as Ca 10 (PO 4) 6 (OH,F,Cl) 2, and the crystal unit cell formulae of the individual minerals are written as Ca 10 (PO 4) 6 (OH) 2, Ca 10 (PO 4) 6 F 2 and Ca 10 (PO 4) 6 Cl 2. The mineral was named apatite by the German geologist Abraham Gottlob Werner in 1786, although ...
