Specimen Size: 2.5 cm specimen.
Field Collected: Bob Janules
Catalog No.: 1724
Notes: This is Bob Janules' kulanite specimen before splitting sample for NH species display.
Specimen Size: Zoom view of about 1 cm zone of kulanite specimen.
Field Collected: Bob Janules
Catalog No.: 1724
Notes:
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.
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
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 4.3 mm field of view
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo
Notes: An EDS analysis of this specimen identified kulanite as the species.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2 mm field of view
Field Collected: Bob Wilken
Catalog No.: A Bob Wilken specimen and photo
Notes:
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.
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.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 4.5 mm field of view. Dark-green kulanite crystal, partially obscured in vug.
Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob.
Catalog No.: u2413
Notes: This is relatively large for a Palermo kulanite crystal.
Locality: Palermo Mine, N. Groton, NH
Specimen Size: 2.0 mm field of view. Dark-green kulanite crystal.
Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob.
Catalog No.: u2414
Notes: This kulanite crystal compares favorably with the one illustrated in The Pegmatite Mines Known as Palermo.
