Clifford Frondel
Published: 01 October 1949
American Mineralogist (1949) 34 (9-10): 692–705.
...Clifford Frondel Abstract Wolfeite, a new species, has the composition (Fe″, Mn″) 2 (PO 4 (OH) and occurs as a hydrothermal alteration product of triphylite at the Palermo pegmatite, North Groton, New Hampshire. Monoclinic prismatic, with a 0 = 12.20 Å, b 0 = 13.17, c 0 = 9.79; β = 108°; Z = 16...

BSEM image of the graftonite-wolfeite±apatite intergrowths. The phosphates are present as fine-grained aggregates interstitial to large magnetite grains. Graftonite constitutes the dominant phase and is intimately intergrown with wolfeite. Small grains of apatite occur along the peripheries of the aggregates. The graftonite-wolfeite aggregates are rimmed by a conspicuous Pb-rich phosphate. Scale bar: 100 μm.

REE patterns of apatite-pyromorphite (six samples) and graftonite-wolfeite (18 samples) intergrowths. The apatite-pyromorphite intergrowths are significantly enriched in total REE and light REE, compared to the graftonite-wolfeite that is heavy REE-enriched. Both patterns show a moderately positive Eu anomaly.
