[meteorite-list] 14C calibration

[E.P. Grondine]

Hi Gran, all - 

Just going through some old mail now.

It was the abnormal dates and regional variations in 14C that got Firestone started. 14C datng was and is one of his specialties. He started out with a supernova hypothesis to try to explain it at first (1999), and then evolved.

It should not be that hard to find one of the multiple statements of the abnormal 14C dates. Paul probably has them right at hand. If not, some of Firestone's papers refereed, published papers are available straight from him.
