Some people have suggested that E chondrites (enstatites) chondrites may
have originated from either Mercury or Venus, mainly on evidence that
the E meteorites seemed to have formed in higher temperatures than
your normal meteorite, and the inner solar system is a good
candidate. However, the evidence to link these meteorites specifically
to either Mercury or Venus is still weak.
The Russians have landed spacecraft on Venus, and some soil analysis was
done. It would seem the results from these experiments could be used
to help determine what a meteorite from Venus would look like.
