Specimen Size: 1.7 mm vug in limonite filled with acicular aurichalcite crystals
Field Collected: Bob Janules
Catalog No.: A Bob Janules specimen
Notes:
Locality: Lincoln Mine (Molybdenium mine), Westmoreland, NH
Specimen Size: 3 cm specimen with 1.5 cm pale apatite crystal in quartz-feldspar matrix
Field Collected: Tom Mortimer 6/2006
Catalog No.: 1531
Notes: Apatite from the Lincoln Mine is fluorescent yellow. The Lincoln "mine" is about a cellar-hole-sized pit.
Locality: Mascot Mine, Gorham, NH
Specimen Size: 1.3 mm chalcopyrite crystal in vug with rhombic siderite
Field Collected: Tom Mortimer
Catalog No.: u1861
Notes: This crystal is quite fresh and untarnished.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 6 mm field of view. Goyazite type 4: "Potato Chip" goyazite, oxide coated.
Field Collected: From a crate of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1876
Notes: Three-inch hosting rock had many vugs with acicular palermoite. Zoom view is an attempt to show individual chips. The chips have irregular edges.
This "potato chip" form is illustrated in Whitmore & Lawrence's book, The Pegmatite Mines Known as Palermo.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 4.5 cm specimen with interior mass of galena
Field Collected: From a crate of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: TBC
Notes: Some micro cerussite crystals appear to be present on the margins of this galena mass.
Galena is listed for the Palermo Mine in Whitmore & Lawrence's book, The Pegmatite Mines Known as Palermo.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 5 cm specimen with pearly white lepidolite mica
Field Collected: From a crate of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: 2007
Notes: This brittle mica is fusible (third photo), a distinguishing characteristic of lepidolite.
Lepidolite is not listed for the Palermo Mine in Whitmore & Lawrence's book, The Pegmatite Mines Known as Palermo.
Other typical Palermo species are present on this specimen including triphylite, ferrisicklerite, siderite, strunzite and quartz.
Palermo is a lithium pegmatite, so lepidolite is not unreasonable.... and this piece is somewhat un-remarkable.... so perhaps this species has been overlooked.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2.5 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: TBC
Notes: Substrate matrix is vivianite. Structure of these sprays resembles Bob Whitmore's gatumbaite specimen, but radial sprays on reverse side are clearly childrenite. Phosphoferrite or reddingite is also present on this specimen.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 7 mm mass of reddish-brown phosphoferrite-reddingite
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1877
Notes: Phosphoferrite is the Fe dominant member of the phosphoferrite-reddingite series. Reddingite is the Mn dominant member. Kryzhanovskite is the oxidized equivalent of phosphoferrite. All are reported from the Palermo Mine. Illustrations in Whitmore & Lawrence's book The Pegmatite Mines known as Palermo , include phosphoferrite (as pale brown pseudo octahedrons) and kryzhanovskite (as dark-brown pseudo-octahedrons). Then we also have landesite, a Fe deficient version of reddingite, that mindat.org reports from Palermo, citing Morrill as a reference... and who knows how that determination was made!
Phosphoferrite: (Fe2+,Mn2+)3(PO4)2 · 3H2O
Kryzhanovskite: (Fe3+,Mn2+)3(PO4)2(OH,H2O)3
Reddingite: (Mn2+,Fe2+)3(PO4)2 · 3H2O
Landesite: Mn2+3-xFe3+x(PO4)2(OH)x · (3-x)H2O
Semi-quantitative EDS can likely differentiate phosphoferrite from reddingite, but differentiating kryzhanskovite and landesite from phosphoferrite and reddingite would require a very skilled mineralogist/chemist.
