Specimen data for Bjarebyite
Tom Mortimer catalog number: u1433
Identification method: Identification supported by EDS analysis. 
This analysis is of a single 0.2 mm crystal from specimen u1433 (shown on the main bjarebyite page) mounted on carbon tape.
The large carbon peak in the spectrum (@277 eV) is likely due to a response from the surrounding carbon tape. Strontium, sometimes
present in bjarebyite, (but not an "essential element"), is absent in this sample. The bjarebyite chemistry is:
(Ba,Sr)(Mn2+,Fe2+,Mg)2Al2(PO4)3(OH)3 .
All the essential elements for bjarebyite show up in this plot.
Notes: The Palermo Mine is the type locality for bjarebyite. This specimen was field collected by Bob Whitmore.
This is the bjarebyite form illustrated in Whitmore & Lawrence's book The Pegmatite Mines Known as Palermo
