Geochemistry: The mass is mainly composed of kamacite (6.82-7.21 wt.% Ni) and taenite (14.45-41.13 wt.% Ni),with minor plessite, schreibersite (34.20-48.86 wt.% Ni) and haxonite (4.68-4.87 wt.% Ni, 0.13-0.27 wt.% Co). Haxonite is present in the center of plessite. Kamacite bandwidth is about 1.0±0.2 mm. Composition of metallic Fe-Ni and the occurrence of haxonite is compatible with IIIE iron.

Classification: Paired with Aletai.
