Mineralogy of the French phosphorites, U.S. Geological Survey Bulletin 509, 89-100 Name changed from hydroxylapatite to apatite-(CaOH): Burke E A J (2008) Tidying up mineral names: an IMA-CNMNC scheme for suffixes, hyphens and diacritical marks, The Mineralogical Record 39, 131-135 Name changed from apatite-(CaOH) back to hydroxylapatite. In addition, apatite-CaOH)-M is renamed to hydroxylapatite-M and is defined as a monoclinic variant of hydroxylapatite and is not considered a distinct species: Pasero M, Kampf A R, Ferraris C, Pekov I V, Rakovan J R, White T J (2010) Nomenclature of the apatite supergroup minerals, European Journal of Mineralogy 22, 163-179
