Valid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Pt,Ir,Os)2(Sb,Bi)3
Possibly the Sb analogue of 'Unnamed (Platinium Iridium Arsenide Sulfide)'.

Co-described with the above species, 'Unnamed (IrAsSb)', and 'Unnamed (Platinum Antimonide Stannide Bismuthide)'.

chromite, ilmenite, cassiterite, 'wolframite', gold, arsenopyrite, molybdenite, cinnabar, and galena.

The phase occurs as angular aggregates made of plates, 0.5-4 microns across, in voids among osmiridium and irarsite, closely associated with the IrSbAs phase.
