APATITE    Palermo Mine, N. Groton, NH
3 cm specimen of massive white apatite.
Species:           APATITE    (Fluorapatite)   Ca5(PO4)3F
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 3 cm specimen of massive white apatite.
Field Collected: From crate of Palermo rocks given by Bob Whitmore.
Catalog No.:
Notes: EDS analysis identified the species as apatite, but did not differentiate apatite-CaF vs. apatite-CaOH. Massive apatite such as this is easily overlooked on the mine dumps. Prior to analysis, I thought this might be massive augelite. Pale rose-colored fluorescence observed with short-wave UV.

Locality:          Palermo #1 Mine core zone, N. Groton, NH
Specimen Size: 6 mm field of view.
Field Collected: A purchased specimen
Catalog No.: u1123
Notes: The web author (Tom Mortimer) prefers the "Apatite-(CaF)" and "Apatite-(CaOH)" names over the Fluorapatite, Hydroxylapatite, names for alphabetical listing because most collectors think of "apatite" first, before considering exact species.

ARROJADITE-(KFe)   Palermo Mine, N. Groton, NH
2.2 cm specimen with 8 mm zone of olive green arrojadite, left-middle.

Species:          ARROJADITE-(KFe)   (KNa)Fe2+(Ca,Na2)Fe2+13Al(PO4)11(PO3OH)-(OH)2
Locality:         Palermo Mine, N. Groton, NH
Specimen Size: 2.2 cm specimen with 8 mm zone of olive green arrojadite, left-middle.
Field Collected: Jim Nizamoff
Catalog No.: 1807
Notes: Arrojadite indicated by EDS analysis .
Raman spectroscopy analysis of two sample points (on the same polished mineral grain used for the EDS analysis) gave a good match for Arrojadite-(KNa). Arrojadite-(BaFe) is not in the Raman data base as of 12/12.
Dark blue mineral is vivianite, cream-colored mineral is siderite.

ARROJADITE Group   Palermo Mine, N. Groton, NH
2.2 cm specimen, 1.5 cm field of view. Pale gray-green granular arrojadite group mineral in tan-yellow siderite.

Species:           ARROJADITE Group
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 2.2 cm specimen, 1.5 cm field of view. Pale gray-green granular arrojadite group mineral in tan-yellow siderite.
Field Collected: Walter Lane - MMNE give-away
Catalog No.: u2026
Notes: A non-stacked photo... not a lot to see here. An EDS analysis strongly suggests an arrojadite group mineral. This group has 14 members.
Arrojadite-(KFeNa) seems to be about the best fit.
The color and luster are consistent with typical arrojadite group minerals at Palermo. Some collectors might simply dismiss this as poor apatite, which it clearly is not.

Locality:         Palermo Mine, N. Groton, NH
Specimen Size: 1.8 mm "cordwood stacked" habit beryllonite crystal - cordwood face end outlined in red in second view.
Field Collected: Walter Lane
Catalog No.: u1263
Notes: These cordwood habit beryllonite crystals can be difficult to discern, (and to photograph - I have not seen another photograph of a similar Palermo specimen). This habit is the same as the specimen shown (more clearly) by the Chickering Mine specimen on the main mindatnh beryllonite page.
These Beryllonite crystals are on a rather remarkable thumbnail size specimen. Also on this specimen are hydroxylherderite crystals, etched acquamarine beryl, and schoonerite crystals. One of the schoonerite crystal groups can be seen in this image on the left side of the beryllonite. The specimen is an interesting study in associations. The etched beryl is likely contributing the berylium for the beryllonite and hydroxylherderite.

BEUSITE ?   Palermo Mine, N. Groton, NH
10 mm field of view. Nut brown scales of beusite? on black siderite.
Species:           BEUSITE ?   (Mn2+,Fe2+,Ca,Mg)3+(PO4)2
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 10 mm field of view. Nut brown scales of beusite? on black siderite.
Field Collected: Walter Lane
Catalog No.: u1463
Notes: A gift from Gene Bearss. Beusite has not previously been reported from the Palermo Mine, or the state of New Hampshire. This specimen was labeled by Gene as lepidocrocite, which is a reasonable visual idenitifcation. Lepidocrocite is a simple iron oxide, dimorphous with goethite. However, a qualitative EDS analysis suggested beusite was the best fit, (no Fe, but lots of Ca, P, and Mn).
Robertsite would seem to be another possibility, Ca3Mn3+4(PO4)3O2·3H2O
It is impossible to photograph these tiny, lustrous, randomly-oriented, scales without getting at least a few bright reflections.

Species:           BJAREBYITE    BaMn2+2Al2(PO4)3(OH)
Locality:         Palermo Mine, N. Groton, NH     (Type Locality)
Specimen Size: 1.5 mm crystal fragment on micromount post
Field Collected: Bob Whitmore
Catalog No.: u1433
Notes: A photo of this Palermo rhombic bjarebyite form was included in the Sept-Oct. 1982 Rocks & Minerals article on the Palermo Mine.
Identification supported by EDS analysis . This analysis is of a single 0.2 mm crystal from this specimen (u1433) mounted on carbon tape. The large carbon peak in the spectrum (@277 eV) is likely due to a response from the surrounding carbon tape. Strontium, sometimes present in bjarebyite, (but not an "essential element"), is absent in this sample. The bjarebyite chemistry is: (Ba,Sr)(Mn2+,Fe2+,Mg)2Al2(PO4)3(OH)3 . All the essential elements for bjarebyite show up in this plot.

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.

Specimen Size: 4.3 cm specimen with close-up view sizes indicated in photos
Field Collected: Dana Jewel
Catalog No.: u1788
Notes: A gift from Dana Jewel, 2015. Carbon tape mounted grain EDS analyses of both the blue and blue-green minerals (4th and 5th photos) suggested a copper sulfate species on a mica substrate, (the source of the Si, Al, and K in the EDS plots). (The pulse counts for these analyses are quite low, but the best data I curently have.) Chalcanthite is likely the most common of the copper sulfates, but there about ten others. Phosphorous not detected, so not pseudomalachite. Bob Whitmore's book, The Pegmatite Mines Known as Palermo does not include any copper sulfate species, so this could be a new one for Palermo.
As the red-brown staining is sometimes indicative of the presence of uranium minerals, the specimen was checked with a scintillometer. No radiation was detected. No fluorescence was observed with SW or LW UV.

CHILDRENITE    Palermo Mine, N. Groton, NH
4 mm barrel-shaped, pinecone crystal cluster
Species:           CHILDRENITE  
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 4 mm barrel-shaped, pinecone crystal cluster
Field Collected: Forrest Fogg -1973
Catalog No.: u1561
Notes: A polished grain EDS analysis from an adjacent broken crystal group suggested childrenite. Calcium is not present in the childrenite formula, so the modest Ca peak in the spectrum is somewhat bothersome. (The large spectral peak at the lowest end of the spectrum is due to the carbon coating.) I have not previously seen the pinecone shape and pale-blue coloration in childrenite.

CRANDALLITE    Palermo #1 Mine, N. Groton, NH
Full specimen, 1.7 cm.
Species:           CRANDALLITE  
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.

CRANDALLITE   Palermo Mine, N. Groton, NH
0.5 mm white crandallite balls

Species:           CRANDALLITE
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 0.5 mm crandallite ball. Second photo shows two on specimen.
Field Collected: Forrest Fogg
Catalog No.: An Bob Wilken specimen and photos
Notes: A semi-quantative polished grain EDS analysis of sample from this specimen indicated a chemistry: CaBa0.1Al4.1P2.9O10 (normalized for one Ca and rounded to nearest 0.1 APFU.)
Crandallite chemistry is: CaAl3(PO4)(PO3OH)(OH)6    Note, EDS cannot detect H. Crandallite is the closest fit available for the EDS indicated chemistry, but still not a particularly good match.
Dana's System of Mineralogy indicates "Ba, Sr and rare earths may substitute for Ca" in crandallite.

DIADOCHITE    Palermo Mine, N. Groton, NH
7 mm fov. Globules of "red-jelly" diadochite on rockbridgeite

Species:           DIADOCHITE     Fe3+2(PO4)(SO4)(OH) · 6H2O
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 7 mm fov. Globules of "red-jelly" diadochite on rockbridgeite
Field Collected: From small box of POD 3 samples given by Bob Whitmore
Catalog No.: u1353
Notes: Diadochite is often the bane of micro-mineral collectors, as it frequently "gunks up" otherwise nice specimens.

ERNSTITE    Palermo Mine, N. Groton, NH
5 mm crystal group

Species:           ERNSTITE     (Mn2+,Fe3+)Al(OH,O)2PO4 · H2O
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 5 mm crystal group
Field Collected: Tom Mortimer
Catalog No.: u147
Notes: A qualitative EDS analysis supports the ernstite identification: EDS analysis
Encyclopedia of Minerals, Robert, Rapp and Weber, 1974, states, in part, Ernstite "occurs as an oxidation product of eosphorite (of which relicts remain)..." Specimen in photo is clearly altered pseudomorph of Childrenite-Eosphorite.
Bob Whitmore's book, The Pegmatite Mines Known as Palermo, lists ernstite for Palermo. However, given that eosphorite is practically unknown at Palermo (Childrenite being common) it would seem that there would be an iron analog to Mn dominant ernstite present. On the ernstite page mindat states: "No name has been proposed for oxidized childrenite, but any such new name would have to have ferric iron > 50 mole percent of the M site."
