Microscopic Diamonds Suggest Cosmic Impact Responsible for Major Period of Climate Change

A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the Younger Dryas stadial, or “Big Freeze.”

Around 12,800 years ago, a sudden, catastrophic event plunged much of the Earth into a period of cold climatic conditions and drought. This drastic climate change—the Younger Dryas—coincided with the extinction of Pleistocene megafauna, such as the saber-tooth cats and the mastodon, and resulted in major declines in prehistoric human populations, including the termination of the Clovis culture.

With limited evidence, several rival theories have been proposed about the event that sparked this period, such as a collapse of the North American ice sheets, a major volcanic eruption, or a solar flare.

However, in a study published in The Journal of Geology, an international group of scientists analyzing existing and new evidence have determined a cosmic impact event, such as a comet or meteorite, to be the only plausible hypothesis to explain all the unusual occurrences at the onset of the Younger Dryas period.

Researchers from 21 universities in 6 countries believe the key to the mystery of the Big Freeze lies in nanodiamonds scattered across Europe, North America, and portions of South America, in a 50-million-square-kilometer area known as the Younger Dryas Boundary (YDB) field.

Microscopic nanodiamonds, melt-glass, carbon spherules, and other high-temperature materials are found in abundance throughout the YDB field, in a thin layer located only meters from the Earth’s surface. Because these materials formed at temperatures in excess of 2200 degrees Celsius, the fact they are present together so near to the surface suggests they were likely created by a major extraterrestrial impact event.

In addition to providing support for the cosmic impact event hypothesis, the study also offers evidence to reject alternate hypotheses for the formation of the YDB nanodiamonds, such as by wildfires, volcanism, or meteoric flux.

The team’s findings serve to settle the debate about the presence of nanodiamonds in the YDB field and challenge existing paradigms across multiple disciplines, including impact dynamics, archaeology, paleontology, limnology, and palynology.


One of the oldest journals in geology, The Journal of Geology ( has since 1893 promoted the systematic philosophical and fundamental study of geology.

The Plait Affair: Gross contempt for one’s better

hoyle and wickramasinghe

Space plankton at ProfChandra

Though Panspermia is not the focus of this blog, I consider the theory and body of evidence a friendly intellectual cousin to the Tusk’s Coherent Catastrophism and worthy of defense on the same grounds. Both philosophies (to use the old term) come from a place of humility in the cosmos — and both endure a fierce majority of opponents who attack not so new ideas with a nasty contempt beneath the expectations of fairly conducted debate. Such displays are particularly grating when the attacker has a demonstrably inferior intellect to the attacked.

An example of wonderful science being dismissed by a low-brow bully is the Plait\Wickramasinghe affair of 2013. Last year Dr. Chandra Wickramasinghe announced the discovery of diatomaceous material in a meteorite, a notion previously endorsed by the President of the United States. This provoked popular science blogger Phil Plait to publish a series of juvenile assaults on the beloved Sri Lankan researcher [here here and here].

Plait is entitled to disagree with Wickramasinghe. But what disgusts the Tusk is his failure to respectfully acknowledge Chandra Wickramasinghe’s profound career of accomplishment in science — indeed astronomy, a subject with which Plait purports familiarity!

Science punk Plait makes no reference whatsoever to Wickramasinghe’s credentials or documented intellectual journey. Indeed, he attacks Dr. Wickramasinghe so directly and recklessly he creepily admits he is operating ad hominem:

Now, you might accuse me of using an ad hominem, an argument that cast aspersions on the person making the claim, and not attacking the claim itself. I’ll get to the claim in a moment, but sometimes an ad hominem is warranted! If Sylvia Brown claims she can predict someone’s future, you would be right to doubt her based on her past, since she has continually failed in every attempt to do so. If Jenny McCarthy claimed botox cures autism, again, you might be forgiven for doubting it based on her previous anti-vaccine and other false claims. You still need to examine the claims on their own merits, of course, but: Fool me once, shame on you; fool me twice, shame on me.

So, to be polite about it, Wickramasinghe is something of a fringe scientist. Who would publish a paper by him?

Phil Plait, January 15, 2013

Did Phil Plait just compare N.C. Wickramasinghe to Jenny McCarthy? It makes me want to ‘fro up.

When Wickramasinghe first walked the yards of Cambridge and published in Nature with his contemplative cohort Hoyle – Phil Plait’s cosmic life was created by Fisher-Price. Wickramasinghe has certainly forgotten more of science than Phil Plait has published.

I was comforted to see one of the few men alive who could adequately empathize with Dr. Wickramasinghe, Bill Napier, send Phil a one-day-to-be-iconic letter below in defense of his dear colleague. I wonder if Phil Plait even knows what it means to be collegial?

Joanne Ballard: Amazing pics from field work in European coversands


In response to an inquiry from the Tusk, Joanne Ballard of the University of Tennessee very graciously provided our blog the unpublished photos, field notes and narrative below from her recent trip to Netherlands. She personally inspects and samples the Usselo Boundary, or black mat of Europe. Absolutely fascinating.

Dear George,

Here is some background on the research of the Usselo horizon sites and narrative for the slides.

I am currently a 4th year PhD student in the Geography Department at the University of Tennessee. I research major paleoenvironmental change since the last ice age, by analyzing lake sediment cores. The proxies I use are pollen, charcoal, stable C and N isotopes, X-ray fluorescence, X-ray diffraction, scanning electron microscopy, light microscopy, and thin sections.

Usselo Horizons in the Netherlands and Belgium typically date to the onset of the Younger Dryas (YD), but in some locations appear to be end-YD. In Germany, this layer is referred to at the Finow soil.
It is a dark, charcoal-rich layer suspended in the coversands. Above is yellow quartz sand, and directly below the dark layer, the sand appears bleached.

While I was a M.S. student at the University of Cincinnati, Han Kloosterman sent me some samples from the Ossendrecht (Netherlands) Usselo horizon. I wet-sieved the sample from the charcoal-rich horizon to concentrate the quartz grains for thin section analysis. The images of this thin section show that all grains are internally fractured, and there are parallel “decorated” lines that may or may not be shock lamellae. There is a quartz grain that appears to have a track with an offset in it that stops in the center of that grain and is radially fractured (Slides 8,9). This suggests to me that there was a rapid shift from a semi-molten state (for a microimpacting grain to penetrate the quartz grain in such a way) followed by fast cooling resulting in the fractures radiating out from the center. The black sphere in the image of the grain with the track in it, is probably an air bubble. The ‘Ossendrecht Medallion’ (Slides 11,12)is a peculiar structure that looks suggestive of a molten quartz grain that was flattened and shock lines were recorded, but I am not an impact physicist. Analyses of the Ossendrecht loose grains using high magnification light microscopy revealed fused grains of quartz. SEM images were also obtained and you can see the comparison of the one grain with Bevan French’s image.

One of the objections from scientists some years ago in discussion about these features, was that they could be detrital material washed in or blown in from some far distant area that had an ET impact.
Therefore, in 2011, I went to the Netherlands and collaborated with several scientists there to collect samples from three different locations, two in the Netherlands (Laarder Wasmeren and Lutterzand) and one in Belgium (Lommel). Colleagues assisting on this trip were Andre Bijkerk; Han Kloosterman; Bas van Geel and Jan Sevink of the Universiteit Amsterdam; and Ferdi Geerts, Conservator at the Museum De Kolonie, Lommel. I took samples from several depths at each site in order to compare the grains at each level. If the grains in the dark layer are all internally fractured at all sites, and levels above and below it are not, it supports the hypothesis that it is an event horizon. I also collected samples from a documented, stand-killing, severe forest fire.

In reviewing these samples under high magnification light microscopy, I found melt glass, fused grains, quartz “needles”, charcoal, wood fragments, and well-rounded black micrograins. These have not yet been analyzed.

At Lommel, we found a section of the Usselo horizon that actually had fine laminations. This set of laminae were not level but arcuate, so not likely to have been a pond or lake depositional setting. These laminae are in situ, and not detrital. I interpret these laminae as algal in nature. Why are these fine algal layers here and nowhere else in the stratigraphic column? My hypothesis is that the surface of the sand was showered by nitric acid rain on a cyclical basis. Each lamina represents one nitric acid rain shower. Nitric acid rain occurs following an extraterrestrial event (Prinn and Fegley 1987, Toon et al. 1997, Kolesnikov and Kolesnikova 2010) and has been documented for the Tunguska event of 1908 (Kolesnikov et al. 1998). The ET shock wave dissociates the N2 in the atmosphere, and the ozone in the stratosphere, and nitrate forms. This rains out over an estimated months to years (Prinn and Fegley 1987).

I have not been able to do a comparative analysis of the different levels at the four sites using thin sections yet, as I have not been able to secure funding to cover the cost of thin sections and radiocarbon dates.

If anyone discusses any of this unpublished material, please cite me.

Slide 2 Examples of what the Usselo horizon is– a dark charcoal rich layer in the coversands, underlain by bleached-looking sand, and overlain by yellow sand. Important early papers on the Usselo Horizon are Van Geel et al. (1979) Alex Andronikov, of the Lunar and Planetary Science
Institute, Arizona also visited sites in the Netherlands in 2011, and was reported on the Cosmic Tusk.
Slide 3 More views of Usselo horizons from Kaiser et al. 2009.

Slide 8 A peculiar quartz grain with a track or channel in it.
Slide 9 Close up of that track, clearly showing the groove from
exterior to interior of grain, and the central radial
fracture pattern as if from a projectile
Very rapid quenching of molten material may have occurred?
Slide 10 More strange features from the Ossendrecht Usselo thin
Slides 11-12 The “Ossendrecht Medallion”, arcuate lines enclosed in
quartz grains suggest shocking. Grain is fractured at foci
of arcuate lines. This also suggests phase changes of
matter from fluid to solid very rapidly
Slides 12-14 Discussion of traditional markers of an extraterrestrial
event, referencing French and Koeberl 2010. The YDB impact
does contain breccia when you consider the internal
fracturing of the quartz grains. Shatter cones would not
be produced in a sandy area; they require bedrock. There
is possible shocked quartz here, but I need a collaborator
to help assess this aspect of the grains. There is melt
glass, without a doubt.
Slide 17 Comparison of a shocked grain under SEM (French and Koeberl
2010) with a grain from Ossendrecht. May or may not be
the same process.

Slide 23 Lutterzand, near the Dinkel River on the east side of the
Netherlands. This Usselo section was very peaty.
Slide 24 Microscope images of grains from Lutterzand. Fused quartz.
Slides 25-26 There are many of these “quartz needles” at all three
sites. Some appear to be quartz filaments but others that
are tapered on the ends, look like sponge spicules.
Further investigation is needed.
Slide 27 A remarkably fresh looking fragment of wood was observed
under the microscope. It should appear weathered after
all these years. One reason it might retain its fresh
look is by being coated by a layer of quartz. This is not
unreasonable given the fused grains and melt glass in these
Slide 28 Lommel, Belgium.
Slide 29 Microscope image of more elongated quartz needles.
Slide 30 The curved laminae, quartz-rich and probably carbon and
nitrogen rich from the brown organic material that is
likely consecutive algal mats from successive nitric acid
rain showers.
Slide 31 From the bleached layer below the laminae (Lommel), melt
glass with a black grain fused to it.
Slide 32-34 Self explanatory
Slide 35 SEM of one of the grains from the brown organic laminae.
You can see clearly that the dark material is adhered to
the surface of the quartz grain.
Slide 36 Summary of Hypotheses that link the three sites.
Slides 37-38 Many researchers refer to the Usselo horizon as a soil,
which forms slowly over thousands of years. I compare
images of the Usselo horizon with a podzol and show clearly
that they are not the same.
Slide 39 Podzol distribution map
Slide 40 When nitric acid rain occurs, it is damaging to vegetation,
but also has a fertilization effect in aquatic
environments, with massive algal and diatom blooms
occurring. Nitric acid rain has been well studied in
recent times in association with the Industrial Age. Since
1850 pollution from factories has acidified precipitation
with sulfates and nitrates. Diatomists were able to show
the link between onset of factory pollution and
acidification of landscapes and aquatic environments. Some
diatoms prefer more alkaline environments, and others prefer more acidic. By tracking changes in the diatom
communities, they were able to show this connection.
Diatoms, then can be used to reveal nitric acid rain peaks
at the YDB. Acidification can be detected in the Greenland
ice cores using ECM (Electrical Conductivity)

International Space Station: Window scum supports Wickramasinghe and Sir Fred’s long contention of teeming life in space



The space station is orbiting the earth in a total vacuum, there is no air, so it is a total defiance of the laws of physics to say these organisms were blown into space from Earth.

‘The only explanation is that they have come from elsewhere in space, and this supports long-held theories that plankton, and therefore all life on Earth including humans, originated from organisms in space.

‘Everything that we have on the Earth is derived from space, including humans.

Russian press release

Wickramasignhe vs. Plait @ HuffPo

Chandra heckled 58:22

The spacewalk….window cleaning @ 2:22

Updates from ProfChandra


The Tusk has long loved Chandra Wickramasinghe since I first came across the cool dude in the 90′s. His work with Sir Fred Hoyle – and every report since — is simply wonderful. Chandra and Fred are either the two smartest wrong guys in the history of modern science or the two smartest period.

Chandra made a widely derided contribution to our understanding last year when he identified aquatic diatoms in a meteorite. According to reports this week, one of which I post in part below, his findings are now supported by the collection of marine diatoms from a window of the International Space Station.

I offer two explanations for this news of the weird. Either:

1) Chandra Wickramasinghe detected diatoms in a meteorite in 2013 and is now vindicated in his long standing prediction that such life forms are relatively common in Space, or;

2) Those trickster Russians are deliberately providing false confirmation of Chandra’s kooky claims for unknown reasons.

Allow me to make a predictive claim as well: Public interest in the Russian findings will provoke critics to further defame Wickramasignhe. I can already hear Phil Plait typing. If you do not know of Plait, he is a “science guy” who specializes in the defense of the known. His too popular blogs rule out and frequently deride anything outside 3˚ of understood.

Shaken not stirred: Zamora proposes ice impacts into fluidized sand surface to explain bays

Just Sayin’: Not all bays were lakes

Chris Moore, Andy Ivester and other skeptics of sudden bay formation recently published a beautiful poster detailing their findings and discussing their conclusions. I was impressed and disappointed. Impressed to see thoughtful research into the bay phenomena, disappointed that it ignored our previous published work determining that at least one (and presumably many more) Carolina bays were never lakes.

Here is their poster:

Download (PDF, 2.89MB)

And below is an excerpt from our abstract concerning the nature of the sands in the eponymous “Howard Bay,” and below that our 2007 Acapulco AGU Carolina Bay poster.

Point is, to refute our conclusion that bays formed suddenly by invoking long-lived “lakes,” Moore and Ivestor need to disprove that, 1) Howard Bay is indeed a Carolina bay formed like all others; and/or 2) It was never a lake.

If our poster helped reignite the terrestrial versus or ET causation debate, then the poster’s conclusions should be addressed directly. It seems the best way would be for Moore, Ivestor and team to core Howard Bay themselves and prove a lake once lived there.

Further analyses of samples in complete core sequences reveal that, unlike typical, peat-rich Carolina Bays, Howard Bay essentially lacks peat, diatoms, pollen, or other organic materials, suggesting that this Bay never stored water for any sustained length of time. Furthermore, several trenches confirm that the deepest part of the Bay is filled with >6 m of cross-bedded eolian sand with no evidence of lacustrine sedimentation. This evidence calls into question prevailing hypotheses (a) that all Bays were lakes and ponds in the past and that their shapes were formed by wave action, or (b) that groundwater movement led to subsidence that formed the Bay….
