Locality: Palermo #1 Mine, Pod 3, N. Groton, NH
Specimen Size: 2 mm crystal, 2 views
Field Collected: From small box of unsorted micros, gift of Bob Whitmore
Catalog No.: u1341
Notes:
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.: u1453
Notes: At 6 mm, this is quite large for a Palermo vivianite crystal.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 2 mm radial spray of vivianite on 0.8 mm clear whitlockite crystal
Field Collected: Dana Jewel - collected underground
Catalog No.: A Gene Bearss specimen - "93TDJ"
Notes: I found capturing the dark blue vivianite with the lustrous clear whitlockite to be very difficult. This is a huge dynamic range challenge for a digital camera.
I have not seen the fan-like presentation of vivianite on a Palermo specimen previously.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 1.2 mm radial spray of vivianite
Field Collected: Dana Jewel - collected underground
Catalog No.: A Gene Bearss specimen - "93TDJ"
Notes:
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 6 mm field of view
Field Collected: From a crate of phosphate rocks gifted by Bob Whitmore
Catalog No.: TBC
Notes: This specimen has been cleaned with iron-out and ultrasonic, but still has some residue coating. The matrix was quite frayable, so I quit will I still had some!
Locality: Palermo Mine, N. Groton, NH
Specimen Size: The largest xl is 1.5 mm long.
Field Collected: ex. Jim Warner
Catalog No.: A Bob Wilken specimen
Notes: [bw] This is a specimen we purchased with a "collection" of Palermo minerals from Jim Warner back in 2003. I think he had bought material from Whitmore and he broke it down and sold a bunch of it.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 1 mm tabular vivianite crystal
Field Collected: Steve Cares
Catalog No.: A Bob Wilken specimen
Notes: [bw] A fat 1.0 mm tabular xl against a nice white UK background (messelite?) amid green ludlamite background.
Locality: Parker Mtn. Mine, Center Strafford, NH
Specimen Size: 0.5 mm vivianite crystal
Field Collected: Gene Bearss
Catalog No.: A Gene Bearss specimen
Notes:
Locality: Chickering Mine, Walpole, NH
Specimen Size: 4 mm fov.
Field Collected: Tom Mortimer
Catalog No.: u1729
Notes: My first guess for this specimen was vauxite, however the EDS analysis showed only a tiny trace of aluminum, an essential element for vauxite. The analysis is consistant with vivianite, with some Mn substituting for Fe. This is particularly intense blue for vivianite.

Specimen Size: The right-most vivianite crystal is 1.0 mm
Field Collected: Clayton Ford ±1970
