Apatite Group

This page kindly sponsored by Matt Zukowski
Name:
The group has its name after the generic name apatite first introduced by the German mineralogist Abraham Gottlob Werner in 1786 (Gerards 1786). It is derived from the Greek ἀπατάω (apatao), to deceive, in allusion to apatite often being confused with other minerals (e.g., beryl, milarite). The designation "Apatite Group" has been used with different definitions in the history of mineralogy. The new nomenclature of the apatite supergroup and its divisons in 5 groups, among them the apatite group was approved by the IMA in 2010 (Pasero et al. 2010).
A group in the Apatite Supergroup which includes hexagonal and pseudohexagonal phosphates, arsenates and vanadates containing the same species-defining cation at both the M1 and M2 sites (Pasero et al 2010).

"Apatite" (sensu lacto) is often used commonly as the generic name for the members of the group which have not been differentiated into specific species through analytical methods and was the name commonly used in the past. Older synonyms for undifferentiated apatites are listed under the Apatite file.
