Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
This section consists of angular and basaltic fragments and individual grains of pyroxene, plagioclase, rare olivine, metal and sulfide set in a clastic matrix. Individual grains range up to 6 mm in size. Particularly prominent are sulfide-rich clasts that appear to have impact-melted textures. Pyroxene is exsolved, with compositions of Fs22-58 Wo1-43 and has Fe/Mn ratios of ~30. Olivine is Fa31. Plagioclase is An92Or1. The somewhat higher than normal abundance of metal and sulfide suggest that this could be a separated silicate clast from a mesosiderite.
