Thin Section Description (,2) - Cari Corrigan, and Nicole Lunning
The section consists dominantly of a fine-grained melt-textured matrix of olivine and pyroxene (1-10 microns) with irregular blebs of metal and sulfide and fragments of mineral grains (200-300 micron grain size.) The mineral compositions are homogenous; olivine is Fa32 and orthopyroxene is Fs26. The meteorite is an impact melt of an LL chondrite precursor, and possibly just a clast within an LL chondrite breccias, as one end of the section shows usual LL chondrite textures.
