Gondwana Buster!

["George Mcghee" <mcghee@xxxxxxxxxxxxxxx>]

I would like to add my name to those wishing to hear more about the putative
mega-impact postulated to precipitate the breakup of Gondawana -- fondly
known as the Gondwana Buster.

To add my two-cents-of-data worth to the original request for literature
citations concerning the GB, I note that on the A CORRELATED HISTORY OF 
EARTH color wall-chart (which is otherwise very nice; produced ty Pan
Terra Inc of Afton MN, USA) the GB appears as a 300+ crater producer right
at the Permian/Triassic boundary.  Thus the GB may have "busted" (ouch!)
more than Gondwana -- it may have produced the "Mother of all Mass Extinctions"
(to paraphrase the title of chapter 9 in Doug Erwin's excellent book on the
same).

Unfortunately for those of us who like to see some hard citations, there
is no specific literature citation given for the GB on the one-page list
of literature which accompanies the wall-chart (alas!), else I would be
happy to pass it on in response to the original request for info.

Please reply ON NET -- things have been a bit quiet lately, and this might
be fun during Final Exam Season.
