    In the Cretaceous Peroid it is accepted that an Asteroid, ( approx 7/9 kilometres diam. ), struct the Earth at great velocity. I want to Know what were the exact co-ordinates, Latitude and Longitude, where this strike occured. The evidence for the strike can now be located at approx; Latitude 27 degree/ Longitude 87 degree. The Gulf of Mexico. But the Gulf of Mexico was in a different location 65 million years ago. My question, where exactly was this location? Given Plate Technonics movement and the spreading of the Pacific Ocean along Plate Faults, it would appear to me anyway that the American Plate has drifted North East from a sub-tropical ( datum line, THE mexican Gulf ), position, causing Greenland also to move North East. I am well aware that Ice now covers most of Greenland, but the name Greenland was given when this landmass was further South and therefore slightly warmer. And I am also aware that the Ice Age covered a large area of the Northern Hemisphere. After the Asteroid strike there was much Seismic Activity, Volcanic Eruptions etc, and perhaps more rapid movement of the Techonic Plates. Anyway, the American Plate carried that Land Mass North East, more of the Land Mass in the North of the Plate came under the influence of the Ice Age. I could Hazard a guess at the Co-ordinates of the Asteroid Strike, but that's all it could be, A hazardous guess. This of course is a serious Thread Posting and the Subject matter is rarely discussed and information difficult to obtain, as I've found out. I'd appreciate opinions, for and against this thread, anything that may lead to further research and enlightenment. Thank you. westwind.

    Kinda of an interesting question. Even the 0 meridian would have moved so is there even a common point of reference?

    Not really. Greenland was most likely a marketing scheme to attract colonist--at its greenest in modern times, it supported sparse grasses and just long enough season to grow potatoes and oats-- its movement over the past 1000 years is trivial to climate change probably a few feet.

    Im a little confused by the opening question to be honest. Westwind are you asking if the paleolatitude and paleolongitude have been determined?

    Dear Paleoichneum. Be kind. You have prefixed your location determinates with the beginning of you Quartar (sic ) Science Forum name. Your expertise is needed here. Though I'm not familiar with the terms paleolatitude and paleolongtitude I take it to mean, in geological terms, the science associated with the position of the Asteroid Earth Strike? And is it Known in Scientific circles? I cannot find references or information dealing with the co-ordinates of the original impact strike on the Earths surface. Given that Plate Technonics have re-positioned the evidence of the impact, discovered at the present time. In the interest of furthering my knowledge of this Life changing Event I'm going to try and calculate an average mean movement per Earth year, say for a reference point, 6mm, and extrapolate this Plate Techonic movement to include distance travelled over 65 million years. Thus arriving at a Strike location 65 million years ago. Im also going to try and relate this movement distance to present geological placement. ie; If the Aseroid where to strike now instead of 65 million years ago, would it take out La Paz? Being at the exact co-ordinates of the original Earth Strike? My maths for Plate Technoic movement will have to suffice with long personal calculations as I have no IT tools, and would probably get lost anyway. Would appreciate your continued support with this Thread. westwind.

    Its looking like the paleolocation is something that is still up in the air a little, with several different possibilities for paleolocation.

    The actual impact crater on the surface of the earth is on the Northern edge of the Yucatan Peninsula.

    If you view this annimation, it puts the impact point at about the same point (~60 to 70 mya), and slightly East of today.

    Dear Lynx Fox. I appreciated the Link. This is the kind of information feed that I need to be looking at. Complicated isn't it? So it would be almost impossible now to locate the original co-ordinates of the Asteroid strike. Several directional Plate movements have taken place confusing the actual distance(s) that the present impact crator could have been repositioned. I imagined a greator movement in a fairly constant direction. This apparently is not the case. When one has a conceptual thought or idea about the mechanics of Earth Principles it is always confounded by the actual Science on the ground. I don't like to be confounded as you know, and try to see and understand why the Science is nearly always right. If one man says the Sky is falling and 1000 say it is not, there is just the possibility that the sky isn't falling. Thanks once again for the Link. westwind.

    Both things are independent from each other, I hope thats clear. About the paleocoordinates normally we can say by paleomagnetic how far south or north something had been lying, so the problem is the longitude which we can just estimate about things like Hotspots which turned out to be mobile over long periods of time.

    A link has been postulated, with stresses induced by the impact initiating the Deccan Traps vulcanism. However, this seems to have predated the KY impact by about three million years. Other researchers have suggested the Deccan traps were triggered by a bolide impact on or near their location. If that was the case it would suggest the KT boundary event and it were products of some external disruption of the Oort cloud.

    A stress that causes a large low shear velocity zone at the bottom of the mantle? Do you really believe that fairy tale?

    n america moving west(actually kinda pivoting off the arctic ocean and rotating in a westerly direction) 3cm/yr x 65,000,000 = 195,000,000 cm =

    our latitude has remained fairly constant since leaving europe pushed by the relentlessly spreading atlantic
    so look to the east to find the coordinates relative to the center of the earth
    the atlantic has been spreading for @130 million years? 1/2 x 130 = 65
    .....................
    circa 8-900 ad
    it was much warmer in greenland when the northmen and women settled there (mideival warm period)
    they could pretty much farm anything that would grow in iowa today
    most of their settlements were on the south east coasts warmed by eddies of the gulf stream
    as the climate cooled, their crops began to fail (as did those in northern europe---especially the grape vines---so they hadda invent the water of life(whiskey) and beer-------yippeeeeeeeeeeeee)
    and they had interreligous strife within their communities ---pagans vs christians and they had sheep
    they exhibited a noticable failure to adapt
    ..................
    wild guess)
    of course an impact of that size and power would disrupt the plate tectonics---increase vulcanism---maybe even alter tilt and rotational speed
    but not by a lot(depending on angle of impact and speed)

    in some parts of the atlantic nearly 200 Ma 130 should be the lowermost

    As I know it really big farming hadn't been possible. And because of their disappearing maybe the community got to little to persist, because of its to little gene pool. (just another wild guess)

    well the asteroid we are talking about didn't even hit through the Lithosphere nearly all kinetic energy was implemented to heat

    A gross exaggeration. They probably tried, but were unsuccessful except for a very few crops--summers were chilly, short, and unreliable.

    Discussions of recent Greenland climate a thousand years ago, really have nothing to do with conditions 65 million years ago.

    granted---no connection to 65million years earlier
    that being said
    there were birch forest in greenland when the northmen got to greenland, and they stayed for 500 years---
    ---ok perhaps i should have said northern minnisota instead of Iowa----for sure, they grew short season crops like rye and barley, flax, corn, cabbage, beets, oats, rhubarb and lettuce---add to these cattle, pigs, horses and dogs and cats---then add in hunting for seals carabu, etc....not really all that bad for the perhaps 5000 people living there until the mwp ended and the little ice age began, then things went downhill fast
