Macroscopic Description: Kathleen McBride
50% brown/black fractured fusion crust covers the exterior of these meteorites. The interiors are heavily fractured and very rusty. MAC 02837 was broken into many pieces.

Thin Section (,2) Description: Linda Welzenbach, Tim McCoy
The sections show an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Several chondrules contain olivine. Weathering is light, with little staining of enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the orthopyroxene is Fs0-6 and metal contains 0.7 wt.% Si. The meteorites are EL3 chondrites and are almost certainly paired.
