Alluaudite-Ca□ (original) (raw)
A material that is NOT an approved mineral species
Formula:
◻4Ca4Mn2+4Fe3+8(PO4)12
Lustre:
Sub-Vitreous, Resinous, Greasy
Crystal System:
Monoclinic
Name:
Originally named huhnerkobelite by Marie Louise Lindberg [Smith] in 1950 for the type locality in Bavaria, Germany. Renamed without redescription by Moore & Ito (1979) for the calcium + vacancy member of the Alluaudite Group. Note: The "huhnerkobelite" of Moore (1965, Am Min 50:713-717) is not true huhnerkobelite, but is the Na-rich member of the series.
