CALCITE   Rt. 101 road cut, Bedford, NH
13 mm cluster of milky-clear, rough, hexagonal calcite crystals

Species:           CALCITE
Locality:          Rt. 101 road cut, Bedford, NH
Specimen Size: 13 mm cluster of milky-clear, rough, hexagonal calcite crystals
Field Collected: Tom Mortimer - 11/19
Catalog No.: TBC
Notes: A single camera shot. Cluster was too large to use with my photo stacking options. Not a lot of contrast for individual crystals.

GEDRITE   Gilsum Road ledge, Surry, NH
6 cm specimen with glassy, dark gray-brown, gedrite blades in pale-blue cordierite.

Species:           GEDRITE
Locality:          Gilsum Road ledge, Surry, NH
Specimen Size: 6 cm specimen with glassy, dark gray-brown, gedrite blades in pale-blue cordierite. Minor pyrite is also present.
Field Collected: Tom Mortimer
Catalog No.: 1614
Notes: Gedrite in cordierite is reported from this site. A polished grain EDS analysis of a sample from this specimen (BC316) gave an APFU calculation of: (Mg5.12,Fe2.28,Ca0.54)Al3.08Si6.0O24.52 , normalized for 6 Si. With Mg >> than Fe, earlier literature would have identified this as magnesio gedrite. Now the IMA identifies Mg rich gedrite as simply gedrite. Note, the presence of aluminum differentiates gedrite from anthophyllite, (also present at this site).
Mindat.org gives a gedrite chemistry as: [ ]{Mg2}{Mg3Al2}(Al2Si6O22)(OH)2 and reports that calcium is a common impurity in some gedrite. Of coarse, an EDS analysis has no way of suggesting how to assign elements to the various parenthesis groups. Additionally, Mindat.org gives a ferro-gedrite chemistry as: [ ]{Fe2}{Fe3Al2}(Al2Si6O22)(OH)2 . American Mineralogist article "Nomenclature of the amphibole supergroup", Volume 97, pages 20312048, 2012, states the [ ] = "A" may be filled by Na, K, Ca, Pb, Li, based on a general formula for the amphibole-supergroup minerals as AB2C5T8O22W2 .

Tabular-hexagonal form

Species:           BASTNASITE
Locality:          Government Pit, Albany, NH
Specimen Size: 0.7 mm crystal, oblique frontal view and top view
Field Collected: Found in large box of uncleaned, untrimmed, Government Pit specimens collected by Leroy Grant of Albany, NH (deceased). Collected in the 1970's.
Catalog No.: u2241
Notes: A visual ID. Crystal embedded in biotite mica, appears to be tabular-hexagonal form, third photo. This form is common for bastnasite.
The R&M article by Bearss & Janules, May/June 1992, pg.160 states: "bastnasite-(Ce) is an extremely rare mineral at Government Pit, occurring as minute (>1 mm) tabular, hexagonal, crystals that are butterscotch in color and have a resinous but frosted luster. The determination of bastnasite-(Ce) was by SEM EDS and XRAY diffraction."

ALBITE on Stilpnomelane   Government Pit, Albany, NH
1.5 mm albite crystal on stilpnomelane
Species:           ALBITE on Stilpnomelane
Locality:          Government Pit, Albany, NH
Specimen Size: 1.5 mm albite crystal on stilpnomelane
Field Collected: Found in large box of uncleaned, untrimmed, Government Pit specimens collected by Leroy Grant of Albany, NH (deceased). Collected in the 1970's.
Catalog No.: TBC
Notes: Photo with Canon T3i, Canon EF 55-255 lens plus B&L microscope objective. Helicon Focus, method B, 39 images.

TORBERNITE   Keyes Mine, Orange, NH
0.3 mm cluster of torbernite crystals
Species:           TORBERNITE
Locality:          Keyes Mine, Orange, NH
Specimen Size: 0.3 mm cluster of torbernite crystals
Field Collected: Found in box of uncleaned, untrimmed, Keyes Mine specimens collected by Leroy Grant of Albany, NH (deceased). Collected in the 1970's.
Catalog No.: u2237
Notes: Green crystals not fluorescent. A dark blue copper mineral (bornite?) is close-by. Matrix is small, rust coated, muscovite crystals, typical of the Keyes #1 Mine. Phillip Morrill does not report torbernite from the Keyes Mines. Several groups of pale-blue, fluorescent yellow, apatite crystals are also present on this specimen.

BORNITE   Keyes Mine, Orange, NH
3 mm field of view
Species:           BORNITE
Locality:          Keyes Mine, Orange, NH
Specimen Size: 3 mm field of view
Field Collected: Found in box of uncleaned, untrimmed, Keyes Mine specimens collected by Leroy Grant of Albany, NH (deceased). Collected in the 1970's.
Catalog No.: u2237
Notes: This specimen also has several small (< 1 mm) groups of torbernite crystals. The copper for the torbernite likely came from this mineral. The deep blue color is not a tarnish, it fully permeates the mineral. A visual ID.
Peter Cristofono opined: "The shape of the crystals is typical for chalcopyrite. So it might be a pseudo of bornite after chalcopyrite. Bornite is easy to distinguish from chalcopyrite by EDS. In chalcopyrite, Cu=Fe, in Bornite Cu is 5X iron."
