MITRIDATITE Palermo #1 Mine, Pod 3, N. Groton, NH 4 cm specimen with zones of massive, olive-green, mitridatite MITRIDATITE Palermo #1 Mine, Pod 3, NH Zoom view of massive, olive-green mitridatite	Species: MITRIDATITE Locality: Palermo #1 Mine, Pod 3, N. Groton, NH Specimen Size: 4 cm specimen with zones of massive, olive-green, mitridatite Field Collected: Forrest Fogg - from flat of unlabeled Fogg specimens from Gordon Jackson Catalog No.: TBC Notes: Mitridatite is much more common at Palermo as a dusty, olive-green, coating on other phosphate and carbonate minerals. A qualitative EDS analysis of this specimen implied a Ca predominant Fe phosphate that (chemically) suggested the massive form of xanthoxenite, Ca₄Fe³⁺₂(PO₄)₄(OH)₂ · 3H₂O, although this specimen would be visually excessively green for this species. However, when the substantially lower EDS detector response at 6.5 KeV vs. 4 KeV was factored in, Fe was likely greater than Ca in my sample. A follow-up XRD analysis gave an excellent match for mitridatite, Ca₂Fe³⁺₃(PO₄)₃O₂ · 3H₂O . I am uncertain as to how common this massive form of mitridatite is at Palermo. I had not noticed it previously. Perhaps it is just over-looked. The hardness measured about 3 with a commercial hardness point set.
WULFENITE Mineral Hill, Wakefield, NH 0.4 mm wulfenite crystal	Species: WULFENITE Locality: Mineral Hill, Wakefield, NH Specimen Size: 0.4 mm wulfenite crystal Field Collected: Gene Bearss - 2013 Catalog No.: u1439 Notes:

ARSENOPYRITE Palermo Mine, N. Groton, NH 2 mm arsenopyrite crystal in siderite. Two views, different lighting angles. A partial second crystal projects from the lower portion of the one lying flat.	Species: ARSENOPYRITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 2 mm arsenopyrite crystal in siderite. Two views, different lighting angles. A partial second crystal projects from the lower portion of the one lying flat. Field Collected: Walter Lane material Catalog No.: TBC Notes: Arsenopyrite is listed for the Palermo Mine. The diamond crystal shape with horizontal striations is diagnostic for arsenopyrite. This is the first Palermo arsenopyrite crystal I have seen.
VIVIANITE Palermo Mine, N. Groton, NH 6 mm flat prismatic vivianite crystal	Species: VIVIANITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 mm flat prismatic vivianite crystal Field Collected: From crate of Palermo rocks given by Bob Whitmore Catalog No.: TBC Notes: At 6 mm, this is quite large for a Plaermo vivianite crystal.

SCHORL South Uncanoonuc Mtn., Goffstown, NH 2.4 cm specimen	Species: SCHORL Locality: South Uncanoonuc Mtn., Goffstown, NH Specimen Size: 2.4 cm specimen Field Collected: Tom Mortimer Catalog No.: 901 Notes:
ZOISITE Crushed Stone Quarry, Westmoreland, NH 4.5 cm specimen of feldspar crystals with tan prismatic zoisite center. ZOISITE Crushed Stone Quarry, Westmoreland, NH 1.5 cm zoom view	Species: ZOISITE Locality: Crushed Stone Quarry, Westmoreland, NH, NH Specimen Size: 4.5 cm specimen of feldspar crystals with tan prismatic zoisite center. Field Collected: Tom Mortimer Catalog No.: 1543 Notes: See specimen 1452 for EDS analysis of zoisite for this occurrence. I was only able to extract a couple of zoisite specimens from this find. These are, unfortunately, quite busted up. Zoisite specimens are rare in NH.
