Betzalel, there are not "ten burn sites". There are AT LEAST 97. http://www.pnas.org/content/105/18/6520.full There can be a fireball from the shockwave heating of the atmosphere; look at literature on the K/T (now K/Pg) impact. e.g. http://www.ucmp.berkeley.edu/education/events/cowen1b.html...

Betzalel, the hypothesized impactor could have broken into many pieces. Also the shockwave generates heat. The geomagnetic research is very important though.

To see a presentation on these charcoal-rich layers in The NL and BE (called Usselo horizons), go here https://www.researchgate.net/profile/Joanne_Ballard and look at Usselo Horizon presentation We collected samples in 2011.

Re: "Ten locations" that got very hot, see Haynes 2008 for a report on so called black mats in the U.S. http://www.pnas.org/content/105/18/6520.short There are also black mats in Venezuela, in The Netherlands, Belgium and Germany. They may be elsewhere as well.

Betzalel, what are these "ten locations"? YD does not appear to have been cold in the southeastern US. Research has been conducted on the sun as a possible factor for Younger Dryas abrupt changes. Renssen et al. 2000 in Quaternary International. Reduced solar activity as a trigger for the...

So...Evo, nitrate can be a combustion marker in ice cores, but it can also be from nitric acid rain following an extraterrestrial event (nitrates form from the dissociation of N2 in the atmosphere and O3 in the stratosphere; these nitrates rain out as nitric acid rain (Prinn and Fegley 1987))...

Evo, there are many more papers in favor of the Firestone et al. 2007 impact hypothesis. Regarding citation #2, read Lecompte et al 2012 for why at least one other researcher (Todd Surovell) could not find the evidence: improper methodology. LeCompte, M. A., Goodyear, A. C., Demitroff, M. N...

betzalel, What burn marks are you talking about?

Hi billiards, You cannot generalize to anoxia here. These are coversands and this is a charcoal and organic-rich horizon.

Hi Alpha Male, Yes I do think it is the YDB. Have you seen Annelies van Hoesel's paper on Usselo horizons and nanodiamonds?
