FW: NASA ANNOUNCES SITE OF "GREAT DYING" METEORCRATER
Devin Schrader asked:

>I wonder if they found enough evidence for
Antarctica?

The password "beckerImpact" sounds like an illusion
to:
Dr. Luann Becker's work in Antarctica.

Some of her web pages are:

"Exploring Antarctica: Understanding Earth and Beyond"
http://beckerantarctica.crustal.ucsb.edu/index.html
http://beckerantarctica.crustal.ucsb.edu/photo_journal_week3.html

Her research papers are found at:

http://beckerantarctica.crustal.ucsb.edu/research_papers.html

Some of them are:

ROBERT J. POREDA and LUANN BECKER, 2003, Fullerenes
and Interplanetary Dust at the Permian-Triassic
Boundary.
Astrobiology. Volume 3, Number 1, 2003
http://beckerantarctica.crustal.ucsb.edu/downloads/poreda.pdf

Basu, A. R., Petaev, M. I., Poreda, R. J., Jacobsen,
S. B., and Becker, L., 2003, Chondritic meteorite
fragments associated with the Permian-Triassic
boundary in Antarctica. Science. vol. 302,
pp.1388-1392.
http://beckerantarctica.crustal.ucsb.edu/downloads/chondritic_meteorite_fragments.pdf

Luann Becker, 2002, Repeated Blows. Scientific
American.
vol. ?, pp. 78-83.
http://beckerantarctica.crustal.ucsb.edu/downloads/blows.pdf

Another paper is:

Impact Event at the Permian-Triassic Boundary:
Evidence
from Extraterrestrial Noble Gases in Fullerene. Luann
Becker, Robert J. Poreda, Andrew G. Hunt, Theodore E.
Bunch and Michael Rampino in Science, Vol. 291,
pp. 1530-1533; February 23, 2001.

Then there is:

11/26/03 - Claystone Breccia on Mt. Crean.
http://beckerantarctica.crustal.ucsb.edu/week3_6.html

This breccia might be at the distal edge of the ejecta
blanket from an impact crater.

Regardless, it will be quite fun wherever they
hypothesize it to be. :-) :-) If this works out,
she will have made her name.

Yours,

Paul
Baton Rouge, LA
