Formula:
Mn2+3Cr3+2(SiO4)3
Member of:
Unique combination of elements. The Cr analogue of 'blythite', calderite, momoiite, and spessartite; the Mn2+ analogue of uvarovite and knorringite (if it truly belongs to the garnet supergroup).
Found as rounded to spherical inclusions, 1 to 30 microns in size, in Cr- and Ni-bearing grains of γ-Fe in alluvial sands from a Pt-bearing serpentinite from an unspecified locality of the Russian Far East. Larger grains are chemically zoned. Some analyses correspond to a Ti- and Cr-enriched variety of 'blythite'.
