Original Classification Lunar-Anorth. Breccia
Macroscopic Description - Kathleen McBride
The exterior of this meteorite is smooth with no obvious fusion crust. There is a thin yellow ochre film on two surfaces, possibly weathered fusion crust. The meteorite is obviously brecciated and one face also has penetrating fractures. The interior reveals gray clasts in a matrix of dark material that has within it smaller <mm sized white and gray clasts. This lunar breccia is moderately hard, with softer gray clasts.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The section consists of an extremely fine-grained matrix with isolated mineral grains and fine- to coarse-grained basaltic clasts in all size ranges up to 1 mm. Dark/opaque clasts exist in this meteorite that do not appear in MIL 090034. Microprobe analyses reveal olivine of Fa16-46, pyroxene in a wide range of compositions from pigeonite Fs19-30Wo4-7 with intermediate and more FeO-rich compositions (one pyroxene of Fs51), and plagioclase of An86-96. The Fe/Mn ratio of the pyroxene averages ~62. This meteorite is a basalt-bearing anorthositic regolith breccia.
