[meteorite-list] Tunguska event

[Dave Harris]

Hi,
..As  I am going to acquire a piece of a tree from the Tunguska site (Univ.
of Bologna trip, 1991) - It seems to me that the present (and plausible)
belief is that it was caused by a low altitude explosive breakup of a stony
meteorite.
Does anyone have any ideas if the meteorite was classifiable from the
microscopic remnants in the trees, and also, any good definitive sites (even
in Russian - I can deal with reading that!) that I could check out?

thanks
dave
