[meteorite-list] List of meteorites from Vesta?

[Jeff Kuyken]

Hi Tracy,

Yes, the meteorites that are actually called "Dunites" are believed to be 
from Vesta and represent a piece of the puzzle that had seemed to be missing 
from Vestan samples for years.

A very important find was made in the form of two NWA's... specifically NWA 
2968 (Dunite) and NWA 3329 (Diogenite). The amazing thing is that these two 
meteorites were found together with a few samples actually having both 
lithologies, thereby linking these "Dunites" with Diogenites and therefore 
strengthening the link with Vesta. Of course there is more to it than that 
but that's my basic understanding of it. Try these links for some 
interesting reading:

However, your point is also valid in regards to the Chassignites. The term 
dunite generally refers to an olivine-rich rock which Chassignites are and 
why they have been dubbed as Martian dunites in the past.

Cheers,

Jeff

I had thought that dunites were Martian, like Chassigny. Have dunites been 
identified from other sources?

Best!
