Locality: Chickering Mine, Walpole, NH
Specimen Size: 2.5 mm field of view. Onion habit whitmoreite.
Field Collected: Tom Mortimer
Catalog No.: u1657
Notes: This onion habit of whitmoreite is defined as "Type 4" in Whitmore and Lawrence's book The Pegmatite Mines Known as Palermo.
Locality: N. Sugarloaf Mtn., Bethlehem, NH
Specimen Size: 2 mm gadolinite crystal
Field Collected: Tom Mortimer - May, 1989
Catalog No.: 644
Notes: This is a re-do of an earlier photo.
Reference: "Pegmatite and Miarolitic Cavity Minerals of North Sugarloaf Mountain Bethlehem New Hampshire", Whittemore and Janules, Rocks & Minerals, Vol. 65, No. 4. "SEM EDS analysis .... showed compositions intermediate between gadolinite-(Y) and gadolinite-(Ce)"
Locality: New Hampshire
Specimen Size: 6 mm field of view.
Field Collected: B. Gilker - 1980's
Catalog No.: u099
Notes: The Gilkers were an older couple that lived in Amherst, NH for many yeras. They were members of the Nashua Mineral Society to which I also belonged. When they moved away (1992), they invited me to their home to see if I wanted any of the material they were leaving behind. I saw little that I wanted, but did spot a feldspar chunk with many micro bertrandite crystals, (in the house roof drip-line area). Unfortunately, they did not recall where they had found it, but were quite certain that it was from one of their New Hampshire collecting trips. These are quite nice for NH bertrandites. A good example of the importance of recording where your specimens were collected.
The granular material on the crystals is bonded to the bertrandite. There appears to be some green mineral included in this, perhaps epidote.
Locality: Beauregard Mine, Alstead, NH
Specimen Size: 1.5 mm field of view. Horizontally oriented clear bertrandite prisms.
Field Collected: Tom Mortimer
Catalog No.: u1444
Notes: At the Beauregard Mine bertrandite is found in highly altered beryl crystals. Big crystal collectors usually reject these. Often these crude, brown-tan crystals have to be broken open to expose the micro bertrandite.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 6 mm field of view.
Field Collected: Walter Lane material - a MMNE give-away
Catalog No.: u1598
Notes: My visual ID for these balls was crandallite. The Microvision EDS analyses indicated just a simple calcium phosphate, apatite. A fluorine response (@ 677 eV, above the 525 eV oxygen peak) is totally absent in the EDS spectrum, indicating these balls are hydroxylapatite. Tabular apatite crystals are also present in this view.
Locality: Charles Davis Mine, N. Groton, NH
Specimen Size: 4 mm field of view
Field Collected: Bob Wilken
Catalog No.: u910
Notes: I am labeling the greenish crystal laths as souzalite of the gormanite-souzalite, pending EDS analysis. At Charles Davis, the greenish crystals of the scorzalite-lazulite series have been analyzed to be Mg>Fe, so lazulite. So am taking a "leap of faith" that these greenish crystals of the gormanite-souzalite series are also Mg dominant, so souzalite.
