Macroscopic Description: Kathleen McBride
The exterior of this meteorite is covered by dull, thin, black
fusion crust. Chondrules are visible through the fusion crust
which covers 90% of this meteorite. The interior is a dark gray
matrix with some light gray patches visible. This meteorite is
loaded with chondrules, several mm in diameter, the largest seen
is 7 mm. The meteorite has a high metal content and has rusty
patches with metal veins. This ordinary chondrite was very heavy
and difficult to break.
Thin Section (,2) Description: Brian Mason
The section shows a close-packed aggregate of chondrules (up to
1.8 mm across), chondrule fragments, and mineral grains in a dark
matrix containing a moderate amount of nickel-iron and troilite.
The meteorite is considerably weathered, with limonitic staining
throughout the section. Microprobe analyses show olivine and
pyroxene of variable composition: olivine, Fa19-27,
mean Fa21; pyroxene, Fs7-23. The meteorite
is classified as an H3 chondrite (estimated H3.7).
