Brown fusion crust with red/orange rust covers 50% of the exterior of this meteorite. The interior is a black matrix with red/orange rust and metal throughout. |
The section exhibits numerous small, well-defined chondrules up to 1.5 mm in a black matrix of fine-grained silicates, metal and troilite. Polysynthetically twinned pyroxene is abundant. The meteorite is moderately weathered. Olivine is Fa15, pyroxene is Fs5-14. The meteorite is a low FeO chondrite of type 4 (Russell et al., MAPS 1998). The meteorite is similar to Willaroy and Suwahib (Buwah). |
Some low FeO olivine chondrites we previously announced as "Chondrite Ungrouped", but with the similarities in petrologic type, and numbers growing, it became clear that classifications need to be made consistent so we have re-classified this as "H4 (Anomalous)". |
