Even More Younger Dryas Impact Hypothesis Papers

Saturday, June 19, 2010 10:14 PM

While using Google Scholar, I found even more recent papers
about the Younger Dryas and related impacts.

They are:

Haynes, C. V., Jr., J. Boerner, K. Domanik, D. Lauretta, J.
Ballenger, and J. Goreva, 2010, The Murray Springs
Clovis site, Pleistocene extinction, and the question
of extraterrestrial impact. Proceedings of National
Academy of Sciences.

http://www.pnas.org/content/early/2010/02/09/0908191107.abstract

The abstract to this paper states:

“Magnetic microspherules have terrestrial origins but
also occur as cosmic dust particles. We failed to find
iridium or radiation anomalies. The evidence for
massive biomass burning at Murray Springs is addressed
and found to be lacking. We could not substantiate some
of the claims by Firestone and others, but our findings
do not preclude a terminal Pleistocene cosmic event.”

Also, a paper by the proponents of the Younger Dryas Impact
Hypothesis appeared in a very obscure Russian journal. It is:

Firestone, R. B., A. West, Z. Revay, J. T. Hagstrum, T. Belgya,
A. R. Smith, and S. S. Que Hee, 2010, Analysis of the Younger
Dryas Impact Layer. Journal of Siberian Federal University.
Engineering & Technologies, vol. 3, no. 1, pp. 30-62.

This issue also contains a paper about an alleged impact
crater strewn field in Germany. The paper is:

Ernstson, K., W. Mayer, A. Neumair, B. Rappenglück, M. A.
Rappenglück, D. Rudhaus, and K. W. Zeller, 2010, The
Chiemgau Crater Strewn Field: Evidence of a Holocene
Large Impact Event in Southeast Bavaria, Germany.
Journal of Siberian Federal University. Engineering &
Technologies, vol. 3, no. 1, pp. 72-103.

I have not had the time to read through any of these papers.
Therefore, I cannot comment in any detail the validity of their
arguments. Therefore, if a person has any disagreements
with what they argue, contact the authors, not me.
