Hello,

after years of work in collaboration with the lab, an interesting result about
NWA 2968... I obtained in 2005 a bag of individual meteorites, with two type of
achondrite. A part have been classified as diogenite, with the name NWA 3329 (
http://tin.er.usgs.gov/meteor/metbull.php?code=33653 ). For the other specimens,

after sended few pictures, and finally a thin section for direct examination, to

the original lab performed the classification, it was clear I had new specimens
of NWA 2968. NWA 3329 and NWA 2968 found together? Linked, or not?

At this time, I worked for classification of other stones with Jean-Alix Barrat
(Angers University, France), the well known french HED lover and specialist. I
submitted the problem to him. The first answer was maybe found together, but
geneticaly not linked. After years of phone calls, and studies on my specimens
of NWA 2968 and NWA 3329, here is the result :

Formed in different area of the HED parent body, NWA 3329 and NWA 2968 have been

mixed as xenolith in a new matrix (probably mesosideritic host) and have been
found in the same strewnfield on Earth. A real diogenite and a real vestan
dunite (the first, the only at this time!) I have for sale :
