Macroscopic Description - Kathleen McBride and Cecilia Satterwhite
Thin brown/black fusion crust is present on the fractured exterior surfaces. Areas without fusion crust have brown oxidation and rusty areas. The interiors are rusty with crystalline texture and visible metal.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
These sections are similar enough that one description suffices. 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, including daubreelite. Microprobe analyses show pyroxene is Fs1-17, though most are Fs1. Kamacite ranges from 2.4-2.7 wt. % Si. These meteorites are EH3 chondrites and are probably part of the MIL 07241 pairing group.
