Petrographic Description: Arch Reid
The meteorite is a fine breccia of pyroxene and feldspar fragments with also a large number of small lithic clasts. The matrix is very fine grained; individual mineral fragments range up to 1.2 mm. Larger mineral fragments show evidence of deformation and some pyroxene grains show exsolution. Clast types include: 1) small dark aphanitic clasts, up to .7 mm; 2) fine grained eucrite fragments up to 1 mm, the most common clast type, and; 3) recrystallized eucrite, one clast 2.1 mm. There are also a few small fragments of brown devitrified glass. The pyroxenes analysed are all pigeonites, Wo7En59Fs34 to Wo14En35Fs52, with a range of Ca contents and Mg/Fe ratios. Feldspars range from Or.1Ab4An96to Or.7Ab16An83. No very high Mg pyroxenes were found and the meteorite is a polymict eucrite or a howardite.
