Notes:
# NASA data for BTN 00301 Weathering: B Fracturing: B Pairing: BTN 00301 Fa: 38-8 mol % Fs: 21-5 mol %
The exterior of these chondrites have approximately 50% brown/black fusion crust with polygonal fractures and oxidation haloes. The interiors are composed of a black matrix with numerous chondrules that are gray, white and rust in color. The size range is 1-2 mm in diameter. There are various odd shaped inclusions 1-3 mm in length of the same colors as well as some that are tan in color. These meteorites are hard.
These sections exhibit numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Silicates are unequilibrated; olivines range from Fa₁₋₃₈ and pyroxenes from Fs₂₋₂₁. The meteorites are H3 chondrites (estimated subtype 3.3).
