Locality: Palermo Mine, N. Groton, NH
Specimen Size: 11 mm field of view
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1885 - Reddingite group on specimen backside
Notes: This is the EDS analyzed (main page) specimen.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1 mm parallel growth of clear Reddingite xls.
Field Collected: A purchased specimen
Catalog No.: u649
Notes: Identification provided by mineral dealer, Sauktown Sales, from whom the specimen was purchased. Reddingite is listed in Bob Whitmore's book, The Pegmatite Mines Known as Palermo, but no illustration is provided. Fleischer (2008) does not include Fe in his formula, only Mn.
This was the New Hampshire minerals species display specimen until 2016, when it was substituted for by a better specimen with EDS confirmation.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3 mm field of view (zoom view 1 mm)
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1886
Notes: These octahedral crystals are a different form than the radial columnar form analyzed 3/16. However these were in the same tub of Palermo rocks with the previously confirmed reddingite. An EDS analysis from this specimen also indicated the Mn dominant species of the reddingite-phosphoferrite series.
There are many species on this micro-boxed specimen: reddingite, vivianite, ludlamite, strunsite, siderite, pyrite, and messelite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 0.7 mm field of view. Pair of reddingite bipyramids.
Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore
Catalog No.: u1868
Notes: I have this labeled as reddingite. It is similar to the specimen that I had a reddingite analysis, u1886. Reddingite is Mn dominant vs. kryzhanovskite, Fe dominant. This is a redo of an earlier photo... much better than before. These are quite nice for reddingite, but I likely should check.
Jim Nizamoff opined: "I don’t recall seeing any reddingite at P#1 personally but I am sure it is there (just need analysis as usual). I checked my analyses from P#2 and pretty much everything I tested was kryzhanovskite (if anything there might be garyansellite present rather than reddingite as one of the samples had fairly high Mg). The crystals in your image are quite nice. Due to the fact that they are so dark I would suspect that there is likely a fair amount of Fe3+ present and would therefore be landesite if Mn dominates overall. I believe that the darker the color the more likely the Fe has been oxidized to Fe3+ "
