The section shows numerous chondrules (up to 1.2 mm across) and chondrule fragments in a brown to black matrix containing some troilite and nickel-iron. Weathering is extensive, with limonitic staining and patches of brown limonite throughout the section. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa7-27, mean Fa16; pyroxene, Fs14-18. The meteorite is classified as an L3 chondrite (estimated L3.6). |
