Another zoom view of about 1 cm zone of kulanite specimen.

Locality:          Charles Davis Mine, N. Groton, NH
Specimen Size: Another zoom view of about 1 cm zone of kulanite specimen.
Field Collected: Bob Janules
Catalog No.: 1724
Notes: On my monitor, the kulanite color in this photo is about right for when the specimen is illuminated with bright incandescent (SOLUX) light.

KULANITE   Palermo Mine, N. Groton, NH
2.5 cm specimen with surface of crystaline green kulanite.

Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 2.5 cm specimen with surface of crystaline green kulanite.
Field Collected: From crate of Palermo rocks given by Bob Whitmore.
Catalog No.: u1093
Notes: This kulanite specimen verified by EDS analysis. As stated by Fleischer & Mandarino, American Mineralogist 1977, Vol. 62, pg. 174: "Kulanite is the triclinic, ferrous iron-dominant analog of bjarebyite." The EDS plot for this specimen clearly shows the iron (Fe) component exceeding the manganese (Mn) component.
Kulanite:     Ba(Fe2+,Mn2+,Mg)2(Al,Fe3+)2[OH|PO4]3
Bjarebyite: (Ba,Sr)(Mn2+,Fe2+,Mg)2Al2[OH|PO4]3

KULANITE   Palermo Mine, N. Groton, NH
3 mm zoom view. Some kulanite crystal faces.

Species:           KULANITE
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: 2.2 cm specimen, 3 mm zoom view shows some crystal faces. Dark forrest-green embedded blades of kulanite.
Field Collected: Walter Lane - MMNE give-away
Catalog No.: u2025
Notes: An EDS analysis (BC175 - 3/2/17) indicated a chemistry of: (normalized for 2 Al):
Ba0.33(Fe1.1,Mn0.6)Al2(PO4)3(OH)3    + 20 extra O.    Light on the barium.
Kulanite chemistry is: BaFe2Al2(PO4)3(OH)3       Kulanite is the only species chemistry that comes close to the iron dominant phosphate indicated by the BC175 analysis. The color and luster are consistent with kulanite.

KULANITE   Palermo Mine, N. Groton, NH
Kulanite mass - 5 mm across

Species:           KULANITE
Locality:          Palermo Mine, N. Groton, NH
Specimen Size: Kulanite mass - 5 mm across
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo.
Notes: Atomic percents from EDS: [bw] 0-42.90; Al-8.36; P-16.92;Ba-9.22; Mn-11.51; Fe-11.10. All except Mn are essential for Kulanite (apparently Fe dominant). Kulanite can have Mn as non-essential.
