[meteorite-list] Clay meteorites?

[lebofsky at lpl.arizona.edu]

Hi Carl and Bob:

Humberto Campins is in the same department as Dan Britt who has written
many papers on both asteroids and meteorites (I think he is the one who
perfected the method for measuring meteorite porosities for the work
published by Brother Guy). So, yes, Humberto does talk to meteorite
experts.

Dan has been on a number of papers on the subject of the composition of
asteroids and their relationship to meteorites. Several years ago he was
the lead author on a review of main belt asteroids in the Encyclopedia of
the Solar System and explicitly talks about clay minerals in asteroids and
CI and CM meteorites.
