Nanodiamond Quantification in Pre-Younger Dryas to Recent Age Deposits Along Bull Creek, Oklahoma, USA

Leland C. Bement, Andrew S. Madden, Brian J. Carter, Alexander Simms, Andrew L. Swindle, Hanna M. Alexander, Scott Fine, and Mourad Benamara, Geological Society of America 125th Anniversayr Annual Meeting, 27-30 October 2013, Denver, Colorado, USA, Paper No. 306-8

Sediments recording the Younger Dryas and time immediately before and afterwards reveal a rich story of dramatic regional changes in climate, human cultural artifacts, and floral and faunal patterns. Previously, Firestone et al. (2007) suggested such changes resulted in large part due to an extraterrestrial impact event. Nanodiamonds were suggested as one line of evidence, as they are associated both with meteorites and other impact events from the geologic record. The Bull Creek, OK drainage basin includes nearly continuous alluvial and aeolian sediments from prior to the Younger Dryas through recent time. Whole-sediment digestions performed on a series of samples dated across this time frame, including both a continuous profile in one location and other sites selected due to their sedimentological or cultural significance. Sediment residues were found to contain nanodiamond spikes (190 ppm) primarily in two horizons: the Younger Dryas and the most recent late Holocene. Much lower levels of nanodiamonds were found in some other layers, while no nanodiamonds were identified in many others. The total distribution of nanodiamonds was not correlated with sediment depositional type, duration of exposure, or evidence for cultural disturbance and fire. The Younger Dryas nanodiamond spike was associated with sediments with some of the shortest surface exposure ages, while the late Holocene nanodiamond spike was associated with the longest surface exposure age. With respect to the impact hypothesis, these results both confirm the presence of a nanodiamond spike associated with the Younger Dryas and indicate that these nanodiamonds were deposited over a geologically short duration. On the other hand, large carbonaceous grains putatively identified as hexagonal diamonds were found to be more consistent with graphene/graphane mixtures.

  1. I am loathe to post on any of the other threads but I guess I have this one all to myself. This is where I am at with this. After duking it out on the wiki talk pages again, a noticed a couple of news articles and a press release has come out from the university in Rimouski, Quebec, one reporting a minimum age of Corossol crater as 2.6 million years old, although the abstract claims an age of more like 20 million years old. So Corossol is out if you believe that. I am not familiar enough with their geomorphological arguments to say otherwise. That also puts the Nipigon embayment back in, although that does not seem to gybe with the platinum spike, and the only evidence that definitively supports it is this particular abstract here, which is being presented at 10:30 AM at the GSA in Denver. So if you want more from Andrew Madden on this, all I can suggest you do is call him, or go see it. If I didn’t think this feature was anomalous and roughly in the right discharge area, I wouldn’t be pursuing it much less proposing it as a YD impact remnant. It just seems too crackpotish.

    It would be much easier to falsify the nanodiamonds, but there are so many problems with the YD Glacial Lake Agassiz discharge already that if that isn’t possible then one must replicate the nanodiamond detection or explain it away some other way, or try to find something datable in the Wilmette bed cores.

    So good luck! My reputation is already tarnished.

  2. Nanodiamonds form at temperatures above 2200*C, way too high to be any airburst or serial impact.
    For there to be more than ten million tonnes of spherules covering over four continents would mean a much more massive impact than previously considered. There also must be an explanation for each event that occurred, a reason that the younger dryas now grows so much smaller than the older dryas…
    The only scenario to describe every detail would be a Lunar impact to the Mediterranean sea 13kya, causing mass extinctions, loss of history, technologies, megaflora, megafauna,… and slowing the outer plates and mantle down further in relation to the faster spinning inner core, increasing electromagnetism, gravity and the length of Earth’s day, forcing life to grow more compact…
    …yes, the Moon impacted the Earth to end the Pleistocene…
    [Holocene Impact Working GRoup]
    Devolution follows closely to evolution mostly from extraterrestrial sources… [see- “Pyramids in the Meltrock” and follow Kalopin @archaeologica.org ‘new world’]
    “…find the truths behind the myths…”

  3. Tony –

    Welcome to Cosmic Tusk, but with provisos as follow… 🙂

    … I think even Boslough will disagree that no airburst can develop temps of 2200°C. His airburst models show temps higher than 5500°K (about 5227°C).

    … “…the younger dryas now grows so much smaller than the older dryas…” This is not clear at all what your meaning is. Can you clarify what it means?

    … A lunar impact would not only have wiped out all life on Earth, but there would be a hole hundreds or thousands of miles deep. And I guarantee you that if the Moon hit only 13,000 years ago, it would not be up in the sky right now. The impact would have deprived it of so much of its momentum that it never would have lifted off again. It also would not be ROUND – nor would the Earth.

    … A lot of assertions in a little space, but when you say something like “The only scenario to describe…” – Sounds like you’ve got it all figured out. Glad you do. No one here does.

    … I looked high and low and could find nothing at all about he Holocene Impact Working Group claiming that the Moon impacted the Earth at 13,000 years ago. Would you like to provide a link or reference for that assertion? I don’t think they said anything of the sort.

    *** I am not a blog cop or anything like that, but since not much that you said sounded reasonable, I thought I’d ask you to support what you are claiming/asserting.

    I find that “Pyramids in the Meltrock” leads to a lot of Electric Universe stuff. That isn’t our bag here. And following one of those links leads to blog comments by someone with a user name of “Kalopin”, the name you point to.

    Anyone who asserts that not only did the Moon impact the Earth in 12,900 years ago, but that it hit MORE THAN ONCE does not have MY attention. It sounds pretty silly. It hit and then didn’t STAY hit. And it did this twice. Pardon me while I put on my tin foil hat so that I can stop the government from zapping me with rays…

  4. Okay, let me reason one thing out:

    The Moon is supposed to have hit the Earth, and then flew up into space and took its present place, traveling around the Earth at 385,000 kilometers high and traveling 1,023 km/s (average).

    WOW, that is SOME speed. That is BY FAR the fastest thing I’ve heard of in the solar system (pardon my ignorance if there are lots like that). The Earth travels at only 30 km/s around the Sun. 1,023 km/s is flat out MOVING.

    Comets only travel up to about 70 km/s. I thought that was fast.

    The ratio of momentums of the Earth and Moon is astoundingly high. Momentum is m*v^2. 1023^2/30^2 is about 1163:1. That is huge.

    So this Moon that hit the Earth somehow had to have also lost a lot of its momentum, right? And yet, there it is, flying around us at 1023 km/s. It boggles the mind to imagine what the original velocity was.

    And anything that hits the Earth and bounces off has to be taking a direct path AWAY from Earth – by definition. You hit a pool ball with a cue ball and the cue ball goes directly away from the point of impact. Directly away means, if nothing else, that there is no angular velocity around the Earth. Yet there it is, going 1,203 km/s. Where did the angular velocity come from? Big rockets?

    And look at the Moon and all its craters. If the Moon hit the Earth, where is the big scar we should see? As for that, let’s also ask where the scar on the Earth is.

    13,000 years ain’t a lot of time to mask impact scars. We are able to find impact craters on Earth mostly easily in desert environments, because there isn’t a lot to of weather or underbrush to hide the craters/scars. Same thing with the Moon. It would be really, really hard to not notice a big scar on the Moon.

    I guess we are supposed to believe that electric lightning bolts melted the Moon’s surface – probably just so humans couldn’t see the messed up scar.

    But the big thing to me is that angular momentum. How does one transform ZERO angular velocity into something 34 times as fast as the Earth, in an orbit at right angles from its path away from the impacted Earth?

    And speaking of orbit, how does the Moon JUST happen to have the perfect velocity so as not to go “flying off into space” while also not falling back to Earth? That is a delicate balance which all orbiting bodies must achieve. And this Moon of ours is supposed to have accomplished that just 13,000 years ago?

    An orbit is a balance of centripetal force (gravity) balancing the orbital velocity – essentially exactly. Not enough orbital velocity and the body falls “down” and goes BOOM! on the surface. Too much velocity and the object flies off into space, perhaps never to be encountered again. (Unless it burns up i the atmosphere – and I kind of guarantee that the Moon, made of so much ROCK, is not going to burn up in the few seconds it is falling straight down. Again, I invoke the ZERO angular velocity after its proposed impact with Earth.)

    But, MAN, that 1,023 km/s has me in its grip. That is a HUGE velocity. Now it isn’t going that fast around the SUN. Since it orbits Earth, the mean Moon orbital velocity around the Sun is the same as Earth’s. That 1,0233 km/s is ONLY around the Earth. Damn, that is moving! And that is not the AWAY velocity. The AWAY velocity is essentially zero, on average. That 1,023 km/s is only AROUND the Earth.

    I am stymied as to how the Moon got going that fast, no matter WHEN it got up that much speed.

    Impact of Moon with the Earth 13,000 years ago? Without leaving scrs on both? Without the Moon falling bck in or flying off into space?

    If the Moon was travelling at 1023 km/s PLUS before it lost some momentum in an impact, it was going well over 14.6 times faster than anything else in the solar system.

    Why would ONE body in all of the solar system be going so fast?

    According to the planetary nebula theory, the material in the solar system was all going around at a very narrow range of velocities. Why would ONE body be going 15 times faster than the rest – and never hit anything for 4 billion years? In fact, how could it have been in orbit at this distance from the Sun? The Sun’s escape velocity is only 600 km/s, so the Moon exceeds that by 423 km/s. Oh, it is only going 30 km/sec around the Sun, but if it hit the Earth 13,000 years ago and STILL has a 1,023 k/s velocity in ANY direction, it had to have had even MORE as it approached Earth. Before the impact removed a good portion of its linear momentum and energy.

    One last thing: (Back on impact velocities being destructive…) Such an impact at such a velocity surely would have pulverized the Earth and Moon. That is 465 times as fast as an average type of bullet (around 2.2 km/s). Kinetic weapons only go up to 8 km/sec, and those are designed to simply obliterate whatever they hit. We humans will NEVER produce something capable of going 1,023 km/s. Satellites go about 7.5 km/s.

    The Earth currently is not obliterated nor pulverized. Ergo, this Moon-Earth impact idea is wrong. No matter WHEN it happened.


    * * * * I somehow misread 1.023 km/s as 1,023 km/s. And then went off on that. BIG screw up on my part. * * * *

    1.023 is, of course, much more sensible. Something in my head should have blared a red alarm, but it didn’t. 1,023 km/s is WAY too fast, and my sense of proportion should have caught it.

    My bad. My bad. My bad.

  6. Dear Steve,
    Current physics [and dating] is badly flawed… Disregard the math and observe the tangible evidence… Study the satellite views real close, go through every detail of my research […and do not form a foregoing opinion…]

    The ‘smoking gun’ are the pyramids and temples buried beneath limestone melt rock [the ejecta blanket] that were originally built on top of Chicxulub crater during the Pleistocene. There is an almost perfect arc of limestone across north America. The Ozarks will fit and match-up right at the Betic Cordilleras and the rock of Gibraltar. This would be the only force available to spread out Pangaea from the Mediterranean sea, forcing the Indian plate into the Eurasian plate to form the Himalayas. the only force that could rip an entire tectonic plate up from the mantle to form the Marianas trench…

    What force would be able to bend the thickness of a plate inward on itself to form the Mississippi embayment? What would push a pile of burnt matter into a pile, now known as the Appalachian mountains? What force would exhume massive amounts of limestone, lofting into the atmosphere forming all the unusual anomalies throughout Chile, Peru, the western U.S. and at this same moment form the Ozark mountain range? The only available scenario would be an impact to this planet by its largest satellite, as it would have to have that much mass, weight, volume, density, amount of electromagnetic repulsion and be in orbit…

    Plants and animals grew much larger and lived longer during the lesser gravity days of the Pleistocene. The Gothenburg magnetic excursion may have been a pole reversal but it was also an instantaneous shift, from this Lunar impact to the Mediterranean sea, to cause an increase in gravity, making it impossible for dinosaurs to exist… [as there were many species of dinosaur still in existence before this event. Recently, mass amounts of skin tissue and even feathers were found intact on dinosaur bones in China…and, NO! iron will not preserve skin tissue for 65 million years and NO bones will last that long, Smithsonian!…] The only reason the bones lasted for 13ky is because they were radiated bu this impact and there was no life left in theses areas, [as the Americas were basically sterilized…]

    The current theory of evolution needs revision and this is NOT any ‘young Earth’ hypothesis, as very similar events took place on a regular and repeatable basis.
    This will be the only scenario that will explain every single detail. Please go through every link and study each and every detail, determine the accuracy of this research, feel free to inform me of any inconsistencies [the physics and dating are not evidence and are not even based in reality!] …and please help to correct our science and history… [civilization is MUCH older!]

    Thanks for giving this the study it deserves!;-]
