Bernd, Alan, and List, Thank you both for the diplomatic and informative responses. While we're on the subject, might one of you (or anyone else) expand on, say, the L/LL6 classification designation? Holbrook was recently moved from an L6 to such a classification, and I have a few others in my collection which are not breccias (and presumably are entirely from one parent body and not two) but yet have this classification assigned to them...which, "by definition," would imply connection with both the L and LL parent bodies, presumably anyway. Thanks, and all best, Dave www.fallingrocks.com

(2002) 40Ar-39Ar Chronology of LL Chondrites (Lunar and Planetary Science XXXIII, 1114.pdf). They even discuss *three* models: 1. The onion-shell model 2. The rubble-pile model 3. The re-assembly model Best wishes, Bernd ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
