SIDERITE Palermo Mine, Groton, NH 3.1 mm field of view	Species: SIDERITE Locality: Palermo Mine, Groton, NH Specimen Size: 3.1 mm field of view Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen and photo Notes: [bw] This specimen had been languishing among some UK's. I obviously had considered this to be something more than siderite. But, with time and experience (?) I recognized it for what it is. Yes, in different parts of the specimen there are different degrees of the scalenohedral habit. The brown siderite mass in the middle of the photo (and another smaller group slightly above and to the right) have that Bart Simpson spiky or tufted look.. In the background there's a much paler or whiter looking siderite. Photo taken w. the Amscope Plan 4X; a stack of 81 w. 20 um increments.
FOGGITE Palermo Mine, Groton, NH 1.1 mm Foggite ball FOGGITE Palermo Mine, Groton, NH 1.1 mm Foggite ball FOGGITE Palermo Mine, Groton, NH Zoom view FOGGITE Palermo Mine, Groton, NH Zoom view	Species: FOGGITE Locality: Palermo Mine, Groton, NH Specimen Size: 1.1 mm Foggite ball top two photos. Field Collected: Forrest Fogg Catalog No.: TBC Notes: Bob Wilken gave me a small box of micros, perhaps acquired via Gordon Jackson, labeled "Foggite Palermo #1 N. Groton, F. Fogg 1972-76". The box has about a dozen inch-sized chunks with small quartz crystal vugs and cream colored balls. With one exception these balls are quite smooth. (On one ball I could see squareish foggite plates.) Some vugs had clusters of childrenite. and most chunks had blue zones of scorzalite.I considered apatite for the smooth balls, so checked with EDS. EDS analyses , BC47 result indicated a Ca, Al phosphate (consistent with foggite), but the Ca content was about 3X what foggite would have. I did two probings (weight % oxide) and both gave nearly same result. I do see some tiny squareish plates at highest magnification on ball surface, last two photos. The APFU calculates a Ca:Al:P ratio of about 3:1:1. It should be 1:1:1 for foggite.
HEMATITE on Zircon Hurricane Mtn., Conway, NH 0.3 mm hematite crystal on a zircon crystal	Species: HEMATITE on Zircon Locality: Hurricane Mtn., Conway, NH Specimen Size: 0.3 mm hematite crystal on a zircon crystal Field Collected: Bob Wilken Catalog No.: u2643 Notes:
STRENGITE Valencia Mine, Groton, NH 0.15 mm white strengite crystals on rockbridgeite STRENGITE Valencia Mine, Groton, NH 0.15 mm white strengite crystal on rockbridgeite STRENGITE Valencia Mine, Groton, NH 0.15 mm white strengite crystals on rockbridgeite	Species: STRENGITE Locality: Valencia Mine, Groton, NH Specimen Size: 0.15 mm white strengite crystals on rockbridgeite Field Collected: Dana Jewell - 1989 Catalog No.: TBC Notes: An EDS analyses , VAL06 result indicated strengite with a bit of Al, an allowed minor element in strengite per mindat.org.
GYPSUM Palermo Mine, Groton, NH 2.8 mm field of view	Species: GYPSUM Locality: Palermo Mine, Groton, NH Specimen Size: 2.8 mm field of view Field Collected:Dana Jewell ? Catalog No.: TBC Notes: Matrix is rockbridgeite. My original thought was that this is palermoite, from the luster and striated prism face. A Raman analyses (black trace in plot) by George Adleman indicated gypsum, which after a follow-up visual review, agrees. This is the first clear Palermo gypsum that I have seen. Jim Nizamoff opined on another similar matrix specimen (not a gypsum one) that it was more likely a Fletcher piece.
GYPSUM Palermo Mine, Groton, NH 0.46 mm crystal group	Species: GYPSUM Locality: Palermo Mine, Groton, NH Specimen Size: 0.46 mm crystal group Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen and photo Notes: [bw] The matrix is pretty much solid pyrite. And, the crystallization is pretty coarse and crusty-looking.
PSEUDOMALACHITE in Quartz Palermo Mine, Groton, NH 5 cm specimen	Species: PSEUDOMALACHITE in Quartz Locality: Palermo Mine, Groton, NH Specimen Size: 5 cm specimen Field Collected: Unknown - a purchased specimen Catalog No.: 2158 Notes:
GYPSUM Beebe River Gorge, Campton, NH 1.4 mm field of view	Species: GYPSUM Locality: Beebe River Gorge, Campton, NH Specimen Size: 1.4 mm field of view Field Collected: Unknown - Purchased at the Baltimore Mineral Symposium, 2022 Catalog No.: u2631 Notes: A 1 cm specimen covered with tiny gypsum crystals in a 3/4" black. old-style, micro box. I had to find an edge where crystals protruded for contrast with the black box background.
GREIFENSTEINITE Palermo Mine, Groton, NH 2.2 mm field of view	Species: GREIFENSTEINITE Locality: Palermo Mine, Groton, NH Specimen Size: 2.2 mm field of view Field Collected: J. Demer ? -per label on specimen box of this ex. Art Smith specimen. Purchased at the Baltimore Mineral Symposium, 2022. Catalog No.: u2608 Notes: A 1 cm specimen in a 3/4" black. old-style, micro box. View is a cluster of pale green, stubby-prismatic, crystals. The crystal prism terminations have a stippled texture that is typical of Palermo griefensteinite.
ZIRCON Hurricane Mtn., Conway, NH 2.0 mm field of view	Species: ZIRCON Locality: Hurricane Mtn., Conway, NH Specimen Size: 2.0 mm field of view Field Collected: Bob Wilken, 2022. Catalog No.: u2643 Notes:
