Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3.5 mm chalk-white apatite crystal.
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1899
Notes: Many whitlockite crystals are present on the matrix hosting this apatite crystal. The grayish, oxide-coated, mass to the left of the apatite is whitlockite. These chalk-white apatite crystals are frequently Apatite-(CaOH), however no testing has been done on this specimen.

Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.2 mm cacoxenite ? balls
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1887
Notes: From a rock chunk with an intimate combination of beryl and graftonite. In some zones of the specimen, the graftonite has pretty much dissolved out, leaving behind beryl stringers and cavities for some secondary phosphates, including rockbridgeite, strunzite, minor laueite, and what may be cacoxenite. Cacoxenite is really rare stuff at Palermo... the 16 page Palermo article in the 1981 R&M issue states "only verified in one specimen" ... and (at the time) "only second occurrence in a pegmatite". Also interesting... the formula for cacoxenite in the R&M article does not include aluminum, but the mindat formula now does... as one part Al to 24 parts Fe .... VERY miniscule! Anyway, one small vug in the subject specimen has several yellow tufty balls that could pass for cacoxenite, (shown here). What tilts the ID in favor of cacoxenite is the association with beryl, an aluminum containing silicate ... that may have contributed to the secondary chemistry.

Notes: Blue scorzalite at base of photo.
Stack of 22 images processed with Helicon Focus
Locality: Palermo Mine, N. Groton, NH
Specimen Size: Pair of wardite crystals. 2.3 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1880
Notes: A note in the tub that contained this specimen said: "From loc of best whitlockite '67."
Locality: Iron Mtn. Mine, Bartlett, NH
Specimen Size: Helvite crystal tetrahedrons on matrix. Largest is 1.0 mm
Field Collected: Ex. Inga Burggraf
Catalog No.: u1198
Notes:
Locality: Gingras Farm Locale, NH
Specimen Size: 3 cm specimen
Field Collected: Tom Mortimer - 5/21/00
Catalog No.: 1998
Notes: Lollingite confirmed by EDS analysis. (A low count, noisy, analysis that needs to be repeated.) Small amounts of cobalt are frequently present with iron arsenic-sulfide minerals. Mindat has a page for "Glaucopyrite", "A cobaltian Löllingite with up to 6.44% Co." The Gingras specimen analysis indicates about 2.5% cobalt, that would appear to fit the definition of glaucopyrite.
This is a voucher specimen for lollingite at the Gingras Farm locale. Lollingite has not previously been reported from here.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 3 mm field of view. 0.2 to 0.3 mm crandallite balls on surface of quartz crystal. Full specimen, 1.7 cm.
Field Collected: Steve Cares - 1976. Acquired by Gene Bearss 2005. Given to Tom Mortimer 2014
Catalog No.: u1884
Notes: Crandallite confirmed by EDS analysis, (a polished grain analysis). The silicon peak is believed to be a contaminant. The Br, Re, and Rn notations are likely due to miss-assignments by the EDS peak-matching software. Most of these balls are quite yellow. Exposed interiors are milky.
Whitmore & Lawrence's book The Pegmatite Mines Known as Palermo does not have an illustration of a crandallite, but it does list it for the Palermo #1 Mine. The Sept/Oct 1981 Rocks and Minerals article on Palermo does not list crandallite.
