Reederite-(Y) (original) (raw)

A valid IMA mineral species

07135670017271926063249.jpg

Formula:

(Na,Mn)15Y2(CO3)9(FSO3)Cl

Colour:

Yellow to orange-brown

Name:

Named in honor of Professor Richard J. Reeder, at the State University of New York at Stony Brook, for his significant contributions to carbonate mineralogy. The suffix/modifier follows the Levinson rule for minerals with essential REE and the predominance of, in this case, yttrium.

Presently, the only known mineral with a fluorosulphate (FSO3)- anion.
