# NASA data for MET 01182 Weathering: A/B Fracturing: A Pairing: MET 00570 Fa: 1-23 mol % Fs: 1-23 mol %
90% black/brown fractured fusion crust covers the exterior of this ordinary chondrite. The interior is gray with heavy oxidation in areas and abundant gray and cream colored inclusions/chondrules present.
The section exhibits numerous small, well-defined chondrules (up to 1 mm) with fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. The meteorite is highly weathered. Silicates are unequilibrated; olivines range from Fa₁₋₂₃ and pyroxenes from Fs₁₋₂₃. The meteorite is an H3 chondrite (estimated subtype 3.8).
