... rise to the “apatite supergroup,” which contains over 40 mineral species. The structure and composition impart properties that can be technologically, medically, and geologically very useful. These remarkable characteristics and uses of apatite arise from the arrangement of atoms in the apatite...

...Kimberly Tait; Neil A. Ball; Frank C. Hawthorne Abstract Pieczkaite, ideally Mn 5 (PO 4 ) 3 Cl, is a new apatite-supergroup mineral from Cross Lake, Manitoba, Canada. It occurs as small patches and narrow veins in large crystals of apatite and (Mn,Cl)-bearing apatite in phosphate pods in the quartz...

... to peralkaline. Five members of the apatite supergroup of minerals are reported from the granites. Apatite is a relatively early-crystallizing phase in all rocks, whilst britholite crystallized during later magmatic stages in about half the samples, independent of granite type. There is a major composition gap...

Published: 01 September 2013
Fig. 6 The dominant substitution mechanism in the Palaeogene apatite-supergroup minerals is ( REE 3+ + Si 4+ ) − (Ca 2+ +P 5+ ). Britholite-(Ce) from the peralkaline Ailsa Craig microgranite falls slightly below the 1:1 line, perhaps due to the operation of a second substitution scheme ( Fig. 7a ).
