# NASA data for MET 01057 Weathering: B/C Fracturing: A/B Pairing: MET 96503 Fa: 1-25 mol % Fs: 2-25 mol %
These ordinary chondrites have a dark gray to black matrix with oxidation scattered throughout. Gray, white and cream colored (mm to ½ cm sized) inclusions are visible. Some areas are rusty brown.
These meteorites are so similar that a single description suffices. The sections exhibit numerous large, well-defined chondrules (up to 3 mm) in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Olivines range from Fa₁₋₃₅; pyroxenes from Fs₂₋₂₅. The meteorites are L3 chondrites (estimated subtype 3.6). These meteorites are very likely paired with MET 00489 and MET 00621.
