Name:Informal descriptive modifier, introduced by Waldemar Schaller, joined to a mineral name . Although there are several Mn-bearing varieties of fluorapatite, some have been given unique names (manganapatite) and some have not, e.g. purple apatite and pink apatite. The dark blue apatites owe their coloration to pentavalent Mn and it is apparently the intention to give this unusual high valence substitution a separate name: Mn-bearing fluorapatite, although any Mn-bearing fluorapatite with unknown valence Mn, could be included under this generic name.
A variety of Fluorapatite

A high valence manganese-bearing variety of Fluorapatite, generally containing Mn#5+#. The name "Manganapatite" has been incorrectly applied to this variety.

When Mn2+ and, probably some divalent Fe, replaces Ca, the resulting color may be dull green (McConnell, 1973). When Mn3+ is present, a pinkish or violet coloration results which is typical for some alkaline pegmatites of the Lovozero massif. Some purple apatites have been studied by Mossbauer spectroscopy and the purple color has been ascribed to MnMn4+. Mn5+ can replace P and this will result in a blue color (Johnson, Prener, and Kingsley, 1963; Hughes et al., 2004). For example, fluorapatite with high valence Mn#5+# fluorapatite often forms blue rims around orange lithiophilite grains at the Rb-Ta Elash deposit.

NOTE: The names manganapatite or manganoan apatite has been used to describe certain samples of fluorapatite that contain divalent Mn that causes a golden-yellow fluorescent response under UV. Without the manganese, fluorapatite is frequently unresponsive to UV, although there are other fluorescence activators in the apatites. Large amounts of Mn in fluorapatite, generally > 4 weight percent, are poorly fluorescent to non-fluorescent.
