Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
This meteorite is dominated by fine-grained (~100-200 micron average grain size) basaltic material which occurs as both the matrix and larger individual pyroxene clasts within the meteorite. Two composite clasts are present in the section; one appears to be a melt clast with pyroxene grains with reaction rims, and the other looks like a multi-domained pyroxene that may have been recrystallized. Pyroxene compositions range from Fs56Wo1-5, with lamellae of Fs15Wo4, and plagioclase is An64-99Or0-3. Two olivine analyses of Fa34 and Fa41 were obtained. The Fe/Mn ratio of the pyroxene is ~27-35. The meteorite is a howardite.
