Thanks for the citation, Stewart. I was not aware that the Tunguska event and Younger Dryas had already been connected via ammonia concentration found in ice cores. And it is most intriguing that a special type of higher energy event could be responsible for both. They speculate:
"An analog of the Haber process with hydrogen contributed by cometary or surface water, atmospheric nitrogen, high pressures, and possibly catalytic iron from a comet could in principle produce ammonia." But the kind of energy necessary to produce the amount of nitrates seen - is apparently absent. Since there has been no mention of significant radioactivity - and given there is like to be massive "extra" gain above the physics of normal atmospheric impact dynamics, then LENR should not be ruled out as a contributing source of energy for such events. I wonder if the recent Russian meteor at Chelyabinsk produced significant ammonia or other nitrates and if it too contained Lonsdaleite and nickel? Many hits turn up on google, as expected - but nothing conclusive that I have seen. A cross-connection between three factors: nitrates in the atmosphere, Lonsdaleite carbon and nickel in the bolide, and the lack of large debris evidence (indicative of an atmospheric explosion) would be interesting for further speculation based on the possibility of how perhaps 10 times more energy than can otherwise be accounted for. (notice how many times the estimated of the size of the Chelyabinsk meteor was raised based solely on the energy, and not the visual evidence). In short, if Chelyabinsk was really that large, there should have been prior notice in the ongoing surveys, and if it was comparatively small, as seems to be the case, then the extra energy could have come from a non-nuclear source involving hydrogen and nano-porosity. From: ChemE Stewart At the time of Tunguska, something also increased the levels of Ammonia and Ammonium Nitrate in the atmosphere to significant levels as shown in ice cores. http://arxiv.org/ftp/arxiv/papers/0907/0907.1067.pdf My bet is that the Tunguska "meteorite" had a LENR/vacuum energy core and was actually a BRANE per M Theory, just like a comet. They ionize the air in their surroundings. If rocks can generate 10-15 megatons (up to 1000 times Hiroshima) in the atmosphere without hitting anything why do we need nuclear weapons?

The study is published in Planetary and Space Science. Hold on ... there is more... including the possibility of a Rossi/ LENR connection! <g> Aside from the enormity of the blast and the lack large rock debris, there is an overlooked factoid - the samples which have been found contain an exotic form of carbon called Lonsdaleite - which is somewhere between graphite and diamond ... and can be nanoporous. There has been prior speculation on carbon - in some exotic form or another, as being part of the Rossi secret catalyst... otherwise this Tunguska story is not exactly on topic. This particular form of carbon was found at another special impact site - which also relates to a pivotal period at the end of the last ice age, around 11-13 thousand years ago which is steeped in mythology (the demise of the Clovis culture, the rise of the Gobekli Tepe culture, Atlantis, the flood of Noah, etc). Lonsdaleite has been found as nano-crystals embedded in iron-nickel and dated to this exact time period at Lake Cutizeo near Guanajuato, Mexico, supportive of the controversial Younger Dryas impact hypothesis. That was presumed to be a massive explosion, since melt-glass from it was found as far away as Syria. Lonsdaleite is an allotrope of carbon with a hexagonal lattice. The crystal lattice, is harder and stronger than diamond and usually embedded in an iron-nickel matrix, and there is the important nano-geometry (it is called nano-diamond), and the fact that many meteors contain ice, methane and hydrogen - all of which, taken together with a larger than expected explosion ... hmmm... maybe it is a bit surprising that the Pentagon hasn't taken an active interest in the HotCat... or maybe they have.
