Macroscopic Description: Cecilia Satterwhite Despite the fact that this meteorite is heavily weathered, some brown fusion crust exists and metal is still obvious in the red-brawn to orange matrix.
Thin Section (,2) Description: Brian Mason The section shows a few poorly defined chondrules in a matrix of granular orthopyroxene, with minor nickel-iron and sulfides. Fusion crust is present along one edge. Weathering is extensive, with brown limonitic staining throughout the section. The pyroxene is almost pure MgSiO3 (FeO 0.1-0.7%, CaO 0.7-0.8%). The nickel-iron contains 0.6-0.8% Si. The meteorite is classified as an E5 chondrite.
