Yes, but it appears that comets are essentially carbonaceous chondrites that formed far enough from the sun to not lose their volitile mineral ddihydrogen monoxide. So saying that it is a carbonaceous chondrite doesn't conclude if it iwas a wet one (called a "comet") or a dry one (called an "asteroid"). ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
