These carbonaceous chondrites have brown/black fusion crust with oxidation haloes and rusty areas. The dark gray/black interior has abundant chondrules/inclusions of various sizes and color. Some metal is present. |
These sections exhibit small (100-300 microns), well-defined, metal-rich grains, and up to 2mm chondrules and a few CAIs in a dark matrix of FeO-rich phyllosilicate. Polysynthetically twinned pyroxene is abundant. Silicates are unequilibrated; olivines range from Fa2-33, and pyroxenes from Fs1-23Wo0-2. These meteorites are CR2 chondrites and are similar enough to be initially paired. |
DOM 10344 was removed from this pairing group in AMN 37 no. 2, where it was re-classified as an LL3.4. |
