Notes:
# NASA data for MET 00783 Weathering: C Fracturing: B Pairing: MET 00636 Fs: 0-1 mol %
The exteriors of these meteorites are rust colored. The interiors have a non-descript, brittle, rust colored matrix.
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 Fs₀₋₁ and metal contains ~3 wt.% Si. The meteorites are EH4 chondrites.
