Writeup from AMN 5(1):

Sample No.: ALHA80133

Location: Allan Hills

Field No.: 1018

Weight (gms): 3.6

Meteorite Type: C3V Chondrite


Physical Description: Roberta Score

No fusion crust is present on this shiny reddish-brown specimen. The interior is highly weathered with some rounded inclusions visible.


Petrographic Description: Brian Mason

The section shows a close-packed mass of chondrules and chondrule fragments with a small amount of dark fine-grained matrix. Chondrules range from 0.3 to 1.5 mm in diameter, and show a diversity of type, the commonest being granular olivine and olivine-pyroxene, barred olivine, and fine-grained pyroxene. Transparent pale brown glass is present in some of the granular chondrules. Much of the pyroxene is polysynthetically twinned clinobronzite. Weathering is extensive, with brown limonitic staining throughout the section. Microprobe analyses show olivine and pyroxene have highly variable composition: olivine, Fa0.5-Fa35, mean Fa14; pyroxene, Fs5-Fs30, mean Fs14. The meteorite is tentatively classified as a C3V chondrite.
