Answer: you can't. The classification scheme is lousy.

Two sequences, one for aqueous alteration and one for thermal

one wonder how we would classify a meteorite that is both thermally

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
