# NASA data for MIL 090172 Weathering: B Fracturing: B Pairing: MIL 07590 Fa: 0-13 mol %
Some of the exteriors have black patches of fusion crust, some have fractures and evaporites. The interiors range from a gray to black matrix with moderate to heavy oxidation. All have abundant mm sized inclusions and chondrules in various colors.
The sections are so similar that a single description suffices. The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa₀₋₄₃ and low-Ca pyroxene from Fs₁₋₅. The meteorites are unequilibrated carbonaceous chondrites, probably reduced CV3. These are likely paired with the MIL 07590 pairing group previously reported.
