The section consists of numerous small chondrules (up to 0.5 mm), mineral grains and CAIs in a black matrix; rare metal and sulfide grains are present. Aqueous alteration of the matrix is substantial. One olivine composition of Fa30 was obtained. Pyroxenes are Fs1. The meteorite is a CM2 chondrite. Possible pairing with other CM2s from the Dominion Range should be considered.
