Rruff whitlockite
WebFound as a late hydrothermal mineral in granite pegmatite at the Palermo quarry, near North Groton, New Hampshire, in the following association and sequence: whitlockite and quartz—rhodochrosite—apatite—zeolite. Whitlockite is structurally distinct from graftonite, caryinite, fillowite and apatite. WebThe mineral whitlockite from the Palermo peg-matite quarry near North Groton, New Hampshire, was described by Frondel (1941.) as Ca3(PO+)z on the basis of its chemical analysis. The water lost upon heating was regarded as non-essential. Later, he concluded that whitlockite and synthetically pre-
