Locality: Palermo #1 Mine, Pod 1, N. Groton, NH
Specimen Size: 7 mm pyritohedron (pentagonal dodecahedron) crystal in triphylite matrix. Two views
Field Collected: Bob Whitmore. A Ray Meyers specimen
Catalog No.: A Ray Meyers specimen
Notes: This is an excellent pyrite specimen from Palermo.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3.5 mm field of view. Other views from same specimen included.
Field Collected: From the Mike Swanson collection.
Catalog No.: u2299
Notes: The habit and association are very similar to that shown for fairfieldite in Whitmore & Lawrence's book The Pegmatite Mines Known as Palermo.
The host matrix is rockbridgeite. The rockbridgeite has a lot of inter-mixed pyrite, causing slow disintegration of the specimen.
The small tan crystals a jahnsite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1.4 mm field of view.
Field Collected: From the Mike Swanson collection. Acquired at the MMNE February 2020 Silent Auction.
Catalog No.: u2299
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2 cm muscovite crystal cluster
Field Collected: Bob Whitmore - 1973.
Catalog No.: A Ray Meyers specimen
Notes: Muscovite cluster perched on edge of partial smoky quartz crystal.
Locality: Palermo #2 Mine, N. Groton, NH
Specimen Size: 5 mm field of view
Field Collected: Jim Nizamoff
Catalog No.: A Jim Nizamoff specimen and photo
Notes: Scorzalite crystals are rare at the Palermo Mines. Massive scorzalite is common.
Jim Nizamoff forwarded two analyses from Palermo #2 lazulite-scorzalite series specimens.
[tm] I have neglected tiny bits of Ca, Na, Mn, Ti, F reported in Jim's analyses.
Lazulite: (Fe0.349,Mg0.629)Al2.019(PO4)2.0(OH)2.0
Scorzalite: (Fe0.732,Mg0.211)Al2.069(PO4)2.0(OH)2.0
Locality: Water Pocket Locality, Albany, NH
Specimen Size: 1.5 mm field of view
Field Collected: Bob Wilken
Catalog No.: A Matt Butler specimen photo and PLM images
Notes: Matt reported: "The PLM interference figure image 'best matches' an acute biaxial figure. In this case only the lower right part of it is in the view of my scope at 63x so we can only see one of the 'bullseyes' instead of both. The 2nd image is with a full wave plate filter inserted, and it shows the color change to blue at the bottom of the "bullseye" confirming the xl is optically negative which also matches bertrandite."
Locality: Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.15 mm anatase crystal (tiny !) with clear brookite crystal top center
Field Collected: Tom Mortimer
Catalog No.: u2291
Notes:
Locality: Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.10 mm anatase crystal (tiny !)
Field Collected: Tom Mortimer
Catalog No.: u2291

Locality: Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.10 mm anatase crystal (tiny !)

Catalog No.: u2291
Notes:
Locality: Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.10 mm ilmenite crystal (tiny !)
Field Collected: Tom Mortimer
Catalog No.: u2291
Notes: Also on the u2291 micro-boxed specimen with anatase is this lustrous metallic black crystal. Only about a mm away from the anatase, so assuming ilmenite. I cannot discount the possibility that this is hematite.
Locality: Aggregate Industries Quarry, Raymond, NH
Specimen Size: 0.8 mm zircon crystal
Field Collected: Tom Mortimer
Catalog No.: u2292
Notes: THis is a re-do of an earlier photo
