Black fusion crust with oxidation haloes covers 50% of the exterior. It has a rusty interior. |
The section consists dominantly of a fine-grained melt-textured matrix of olivine and pyroxene (1-10 microns) with irregular blebs of metal with rimming sulfide and fragments of mineral grains (2-300 micron grain size.) The mineral compositions are variable; olivine is Fa16-29 and orthopyroxene is Fs19-22. The meteorite is an impact melt of an L chondrite precursor. It differs texturally and compositionally from MAC 02497. |
