90% of the exterior is covered by dark brown fusion crust with round dark colored weathering spots and some orange rust. Exposed surface is a grey matrix with black, brown and light gray inclusions. Fresh interior is a light colored matrix with some large (~1 mm) gray inclusions and extensive orange rust throughout. |
The section exhibits a few poorly defined chondrules (up to 1 mm) in a matrix of coarse metal and sulfide. Olivine is Fa15 and pyroxenes are Fs5 and Fs13. The meteorite is moderately weathered. The meteorite is a low FeO chondrite of type 5 (Russell et al. MAPS 1998). While the meteorite is similar in mineral composition to Willaroy and Suwahib (Buwah), the texture suggests that it is not paired with either MIL 15293 or MIL 15362 (classified in the Spring 2019 Antarctic Meteorite Newsletter). |
