Hello, I have a question about chondrites' petrological type number assigned after the letters (like H, L, CM or CR ...). I have just read something in internet but I think I have misunderstood something.
Are the numbers from 1 to 7 in sequence or there are two different sequences: 1 to 2 - 3 to 7 ?? 1 to 2 is for the aqueous alteration degree in carbonaceous chodrites (1 high degree, 2 low degree) 3 to 7 is for thermal metamorphism degree? Thanks a lot Ciao <x>x<x>x<x> Francesco ______________________________________________ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
