[meteorite-list] More on the Younger Dryas 'impact event'

[E.P. Grondine]

Hi - 

Since metals predominate in Tunguska impactites, my guess is that Tunguska was caused by one of the last fragments of Encke, a piece of the core of a Encke component cometissimal.

(I hope I haven't said anything too stupid here, but since my stroke I never know anymore - of course, this is long term memory, which was not so severely affected - The impactite researcher was Auduvesky(?) working with Italians (I can't remember from which university anymore.)

I don't know if they ever did use an acid to isolate nanodiamonds -
