Raman spectroscopic study of the mineral qingheiite Na2(Mn2+,Mg,Fe2+)2(Al,Fe3+)(PO4)3, a pegmatite phosphate mineral from Santa Ana pegmatite, Argentina

[Display omitted] •We have studied the pegmatite phosphate mineral qingheiite.•The formula was determined as Na1.39(Mn1.42,Mg0.87,Fe0.642+,Zn0.01)∑2.94(Al0.43,Fe0.353+)∑0.78(PO4)2.99.•The Raman spectra shows the phosphate anion is very strongly distorted.•The presence of water was determined by infr...
