>Just after my post recapping the Chixulub impact crater evidence, I
openned my new copy of the The Planetary Report (the Planetary Society

Impacts, Mass Extinctions and the Galaxy." The article is by Michael
Rampino, one of the well-known scientists who study mass extinctions and
impact cratering processes (and who, with Stothers, borrowed the term
"nuclear winter" to describing an impact aftermath).

A very interesting paper on the Chicxulub structure has been written by
Dr.Christian Koeberl,an authority on impact cratering and impact glasses
including tektites:
Chicxulub-The K-T Boundary Impact Crater:A Review of the
Evidence,and an Introduction to Impact Crater
Studies.Abhandlungen der Geologischen
Bundesanstalt,p.23-50.Vienna,1996.
