Exterior is black with possible fusion crust covering about 30%. Large light grey to light brown round clasts/chondrules up to 5mm are present. One large (1cm) black reflective clast is exposed. There are a few areas of dark red rust. Fresh interior is very dark brown-black matrix with numerous round clasts that range in color form light grey to brown to black up to 4mm. Orange rust can be seen throughout. |
The section shows a close-packed aggregate of chondrules and chondrule fragments up to 2 mm across in a dark matrix containing a small amount of nickel-iron and troilite. Weathering is modest. Microprobe analyses show olivine and pyroxene of variable composition; olivine Fa0-31 and Fs3-9. The meteorite is an LL3 chondrite (estimated subtype 3.6). |
