Weight (g): 9.096
Meteorite Type: L Chondrite (Impact Melt)
    MAC02750

Macroscopic Description: Kathleen McBride
Black fusion crust with oxidation haloes covers 50% of the exterior. It has a rusty interior.

Thin Section (,2) Description: Tim McCoy, Linda Welzenbach
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.
