  CVox3

TKW 2.88 kg. Fall not observed. Purchased 2020 in Morocco.


 


Carlos writes:
This is the only approved meteorite classified as CVox3.

Many samples weighing a total of 2880 g were found by a nomad in northwest Africa. These meteorites were purchased by Carlos Muñecas and Adrián Contreras in Errachidia, from Hmad Ait Hssain.

Physical characteristics: Samples are dark in color, irregularly shaped, and have a partial coating of wind-ablated fusion crust. Chondrules and CAIs are visible on the cut face.

The CV ox / red subclasses have been used in the literature for years. Here's a 2014 reference, see pg. 40 www.arxiv.org/pdf/1408.6581.pdf

www.hou.usra.edu/meetings/metsoc2019/pdf/6372.pdf is one reference that briefly discusses the CV OxA and OxB designations versus CV red (reduced). David Weir's site has more information on these CV variations.

Bernd, do you mean that it is simply an oxidized CV3?

Hello Carlos, as Allende, Axtell and Kaba also belong to the oxidized subgroup, their classification could as well be written like this => CVox3.

Unusual enough appearance that it might have been overlooked had it not been in NWA and many specimens.
