Chemical characterization (microprobe analyses and Möss spectroscopy) showed the chromite to be unique: besides being Zn-rich, complexly zoned and a cation deficient spinel, all the iron was found to be fully oxidized to Fe 3+.

At ⩾1200°C while the surrounding silicate was still partly molten, euhedral taenite with ∼ 50 wt.% Ni began crystallizing in one of the metal-troilite droplets. Troilite nucleated at one edge of the euhedral taenite grain and began to crystallize at ∼870°C. At 320°C the metal phase underwent an ordering reaction and formed tetrataenite.
