[meteorite-list] Franconia AREA (was, Re: ...terminology...)

[Mark]

I agree with Eric too, but for the different dates that Larry refers to (which is mentioned in the same article).  After seeing many diverse rock types in a same small rock mass, I've always felt it's too simplistic to say different class. = different fall.

I would go with the dating in this specific case that indicates different fall events though.
