MET00636

MET00783

Macroscopic Description: Kathleen McBride
The exteriors of these meteorites are rust colored. The interiors have a non-descript, brittle, rust colored matrix.

Thin Section (, 2) Description: Tim McCoy
These two meteorites are tentatively paired. Found 4.5 km apart, they exhibit similar features, although these same features are shared by many EH4 chondrites. 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. Weathering is significant, with staining of some enstatite grains and minor alteration of metal and sulfides. Orthopyroxene is Fs_0-1 and metal contains ~3 wt.% Si. The meteorites are EH4 chondrites.
