Thin Section Description (,2) - Cari Corrigan, Tim McCoy
This meteorite is heavily shock blackened and shock veined. Most olivine grains range from having been mosaicized to micro-melted. Metal and sulfide grains as well as an opaque phase, perhaps chromite, are dispersed throughout the section, occasionally exhibiting micro-melted textures. Olivines are Fa24, pyroxenes are Fs21. The meteorite is an L melt breccia with one relict chondrule but is so heavily shocked that it is difficult to determine its petrologic type. Given the heterogeneity, this preliminary assignment should be followed up with more detailed work involving additional thin sections.
