NWA 8471 (CV3) SOLD OUT

One 314g stone lacking fusion crust was purchased out of Morocco in March of 2014. Classification was done by Dr. Alan Rubin who determined the stone to be a Bali subgroup CV3 with a shock grade of 1 and a weathering grade of 3. I prepared the slices myself which features stunning CAI’s in a dark matrix with multi colored and large chondrules. Each slices comes in a labeled meteorite box.
Petrography as follows:
Microprobe examination of a polished mount shows the rock is an oxidized CV3; it contains abundant magnetite and has little metallic Fe-Ni. It has a preferred orientation petrofabric, suggesting it may be a member of the Bali subgroup. Chondrules are large, averaging 900 μm in diameter. Textural types of chondrules include Type-I porphyritic olivine and olivine-pyroxene and barred olivine. Type-II chondrules are rare. No radial pyroxene chondrules were observed in the thin section. Many of the chondrules are surrounded by igneous rims. The rock contains 5-10 vol.% amoeboid olivine inclusions ranging in length from 0.8 to 5 mm. Olivine Fa4.0±2.6 (Fa0.5-10.0, n=30); Low-Ca pyroxene Fs2.2±1.7Wo1.5±0.8 (Fs0.9-4.7, n=12).
