Classification: Pallasite (Main group)

Physical characteristics: One 306.97 g piece with evident fusion crust.

Petrography (N. Fowler-Gerace, ROM): The meteorite contains ~60% olivine (Fa_13.4, N = 6). The grains are rounded to angular and range in size from ~3-15 mm.

Geochemistry: Oxygen isotopes (Banerjee, Ali, Jabeen, UWO): laser fluorination of acid washed olivine grain separates gave average values of δ¹⁷O = 1.75; δ¹⁸O = 3.70; Δ¹⁷O = -0.160 per mil (N=3). Values plot with the main group pallasites.

Classification: Pallasite, PMG

Specimens: 20 g at ROM
