Abstract The Ulasitai iron was recently found about 130 km southeast to the find site of the Armanty (Xinjiang, IIIE) meteorite. It is a coarse octahedrite with a kamacite bandwidth of 1.2 +/- 0.2 (0.9-1.8) mm. Plessite is abundant, as in taenite, kamacite, cohenite, and schreibersite with various micro-structures. Schreibersite is Ni-rich (30.5-55.5 wt%) in plessite or coexisting with troilite and daubreelite, in comparison with the coarse laths (20.6-21.2 wt%) between the Widmanstatten pattern plates. The correlation between the center Ni content and the half bandwidth of taenite suggest a cooling rate of similar to 20 degrees C/Myr based on simulations. The petrography and mineral chemistry of Ulasitai are similar to Armanty.
