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
