is a synonim of Mn bearing Fluorapatite with formula (Ca,Mn2+)5(PO4)3(F,Cl,OH) or Ca5([P,Mn5+]O4)3(F,Cl,OH) and hardness of 5. 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.From New Hampshire.
