Locality: Palermo #2 Mine, N. Groton, NH
Specimen Size: 0.4 mm crystal cluster
Field Collected: Jim Nizamoff
Catalog No.: u1034
Notes: This is on the same specimen as my New Hampshire mineral display whiteite.
Collected by and gift from Jim Nizamoff. Palermo #2. Fairfieldite from Palermo #2 was analyzed as part of Jim's Palermo #2 UNO thesis.
Jim has stated that fairfieldite is a frequent associate of whiteite at the Palermo #2 Mine.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 3 mm field of view
Field Collected: Ex. Marcelle Webber.
Catalog No.: A Bob Wilken specimen & photo
Notes: Identification method: EDS BC PL_O. Chemistry from analysis gives (normalized for 2 Ca):
Ca2(Mn0.46,Fe0.26)P2O6.8
Locality: Palermo #2 Mine, N. Groton, NH
Specimen Size: 2 mm field of view
Field Collected: Jim Nizamoff
Catalog No.: u2127 - cataloged for whiteite
Notes: There is a nice whiteite cluster on this specimen. Photo is a stack of 87 images with T3i & B&L objective lens.
Locality: Palermo #2 Mine, N. Groton, NH
Specimen Size: 1 mm field of view
Field Collected: Jim Nizamoff
Catalog No.: u2127 - cataloged for whiteite
Notes: There is a nice whiteite cluster on this specimen. Photo is a stack of 20 images with T3i & Nikon Plan 10 objective lens.
This has replaced the fairfieldite front page photo.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3.2 cm high specimen. Cream-colored fairfieldite-messelite with bronze childrenite and deep blue vivianite.
Field Collected: R. Whitmore - 1965-1975
Catalog No.: u2246
Notes: Oct. 2019 EDS analyses, normalized for 2 Ca (BC256, BC256A) gave
BC256A - Ca2(Mn0.36,Fe0.29)P2.2O5.2
BC256 - Ca2(Fe0.38,Mn0.26,Na0.02,Mg0.01,Sr0.01)P2.2O9
One analysis is Mn dominant (= fairfieldite) the second is Fe dominant (= messelite). These two analyses were on the same polished grain, about one mm apart. The BC256 analysis had tiny trace amounts of Mg, Na, and Sr.
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: Turner Mine, Marlow, NH
Specimen Size: 2.5 mm field of view
Field Collected: A Bob Wilken specimen (collected 10/20) & photo
Catalog No.: TURFairfieldite01AS
Notes: [bw] "I'm assuming this IS fairfieldite rather than messelite given the location."
[tm] The Turner Mine appears to be a Mn > Fe pegmatite.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 8 mm tall specimen
Field Collected: Uncertain, perhaps Bob Whitmore.
Catalog No.: Don Dallaire specimen #4004 and photo.
Notes: [dd] The specimen was from Bob Whitmore's collection (No. 167-16TN). His label says "Fairfieldite, Zone No. 4. It is a spherical fairfieldite as described in his book and is quite asthetic.
Locality: Palermo Mine, Groton, NH
Specimen Size: 2.0 mm field of view
Field Collected: Clayton Ford
Catalog No.: u2650
Notes: I am labeling this as fairfieldite. A single isolated crystal in a vug on lumpy jahnsite. With just a single crystal, I will never be certain, fairfieldite or messelite. Fletcher does have a lot of bermanite, a Mn phosphate. The decoration with small jahnsite and rockbridgeite balls adds interest.
