Exploring abrupt climate change induced by comets and asteroids during human history

Just Published: Independents locate ET Black Mat and more in Venezuela

An international team of scientists representing a number of disciplines locate bizarre materials and ET impact markers in a distinct layer of well-dated sediments from the initiation of the Younger Dryas and publish their findings in a major scientific journal.  2007 Firestone et.al. in PNAS?

Nope.  W.C. Mahaney et. al. Geomorphology — March 2010.

In a total surprise to me (and I think the YD team) a new group has emerged and published findings which are strongly supportive of the YDB hypothesis.   They aren’t the first independent party to complement the YDB team’s findings — but they appear to be the best.   It is a very well written paper and includes a number of new discoveries — including Shocked Quartz (Planer Deformation Features), which are diagnostic of impact.

The Tusk will read, re-read and read once more in hopes of elaborating further this evening.


Evidence from the northwestern Venezuelan Andes for extraterrestrial impact: The black mat enigma
Geomorphology Volume 116, Issues 1-2, 15 March 2010, Pages 48-57

A carbon-rich black layer encrusted on a sandy pebbly bed of outwash in the northern Venezuelan Andes,previously considered the result of an alpine grass fire, is now recognized as a ‘black mat’ candidate correlative with ClovisAge sites inNorth America, falling within the range of ‘blackmat’ dated sites (~12.9 ka cal BP). As such,the bed at site MUM7B, which dates to <11.8 ka 14C years BP (raw dates) and appears to be contemporaneous with the Younger Dryas (YD) cooling event, marks a possibly much more extensive occurrence than previously identified. No fossils (megafauna) or tool assemblages were observed at this newly identified candidate site (3800 a.m.s.l.), as in the case of the North American sites. Here, evidence is presented for an extraterrestrial impact event at ~12.9 ka. The impact-related Andean bed, located ~20 cmabove 13.7–13.3 ka cal BP alluvial and glaciolacustrine deposits, falls within the sediment characteristics and age range of ‘black mat’ dated sites (~12.9 ka cal BP) in North America. Site sediment characteristics include: carbon, glassy spherules, magnetic microspherules, carbon mat ‘welded’ onto coarse granular material, occasional presence of platinum group metals (Rh and Ru), planar deformation features (pdfs) in fine silt-size fragmental grains of quartz, as well as orthoclase, and monazite (with an abundance of Rare Earth Elements—REEs). If the candidate site is ‘black mat’, correlative with the ‘black mat’ sites of North America, such an extensive occurrence may support the hypothesized airburst/impact over the Laurentide Glacier, which led to a reversal of Allerød warming and the onset of YD cooling and readvance of glaciers. While this finding does not confirm such, it merits further investigation,which includes the reconnaissance for additional sites in South America. Furthermore, if confirmed, such an extensive occurrence may corroborate an impact origin.

    Rich Murray: Real science hops from failure to failure, from several
    falsifiable hypotheses in confused competition to the next set, until a
    consensus evolves around a surviving paradigm that often uses
    aspects of its predecessors, adding unexpected novel ideas that lead
    to productive questions and more definitive tests, as disparate data
    starts to fit an overall unifying view.

    Right now, we seem to be in a phase of “herding cats” — it seems
    that objects have been hurling every which way during recent times.

    As one of the most unqualified participants, I hope to help raise
    the level of openmindedness and unfettered curiousity in this game
    of truth, for we all honestly hope for outcomes that advance our
    jointly cocreated world, which has so richly benefited from the
    ethical advances of inspired civil rational discourse based on
    publicly shared information.

    We never know we don’t know before we start to know…

    I hope an expert laboratory group will keenly examine the elements
    and isotopes in the commonly found red, white, and dark fragments,
    often as durable surface coatings that may be from high temperature
    and pressure blasts.

    [ We presented a poster presentation the December 2009 AGU
    meeting in San Francisco of some of the Perigee: Zero concepts
    as they pertain to the Carolina bays and their role in identifying
    a possible YDB impact crater.
    A comprehensive review of the conjecture and our
    Heuristic Argument is discussed in this section.

    download HERE.
    Please note that since the meeting, we have demoted Lake Michigan
    in favor of an impact at the Saginaw Bay and Michigan proper,
    although neither hypothesis has proven an adequate solution
    at the present time. ]
