Formula:
(Fe,Rh,Pt)O
Co-described with 8 other oxidic PGE minerals: UM1994-10-O:FeIrPtRh, UM1994-11-O:FeIrRh, UM1994-13-O:FeMnRu, UM1994-14-O:FeIrPtRh, UM1994-15-O:FePt, UM1994-16-O:FePt, UM1994-17-O:FePt, and UM1994-18-O:FePtRh.
As two grains (first - 30 x 50 microns; second - with 40 microns as its largest dimension) from alluvial deposits surrounding a chromitite. Associated mainly with Pt-Fe alloys cooperite, laurite; more rarely with bowieite, malanite, and cuprorhodsite.
Chemically very similar (or identical?) to UM1994-14-O:FeIrPtRh. Possibly a PGE-substituted wüstite?
Variable reflectance (pale gray to creamy white), very strong anisotropy ( steel blue to yellowish beige).
Electron microprobe data (one of the grains), wt.%: Rh 33.65, Ir 1.81, Pt 12.76, Mn 0.06, Fe 35.30, Ni 0.12, Cu 0.11, O 17.10, total 100.90, corresponding to (Fe0.62Rh0.32Pt0.07Ir0.011.02O0.98.
