Neither has anything to do with your fictional impactor and it should be pointed out that India moved to its correct position over a period of 100 million years and NOTHING like your fictional Greenland movement within the last 12,000 years, the latter of which is unevidenced. cormac I have decided to start another thread on Atlantis... i propose an honest discussion regarding the geoid, and Atlantis. I will forward new information i have collected by posting it here. Something happened that changed the whole planetary gravity and produced the regional geoid high, we can witness at the northern sector of Mid Atlantic Ridge. The region from in front of Gibraltar until about 40 km from Iceland is the thickest oceanic crust of the longest mountain range in the world, the MAR. I did two images of the geoid at the same scale and overlapped them as you can see above. For all we know it is very similar to the shape of Greenland. This can't be denied, i hope. The geoid anomaly in the Atlantic is also coincident with the topography of the ocean floor. Quote North Atlantic geoid high, volcanism and glaciations Abstract [1] Shallow topography, geoid high and intense volcanism in the northern Mid Atlantic Ridge are interpreted as enhanced by the loading on the adjacent continents by ice caps during upper Cenozoic glaciations. The load of ice packs on the continental lithospheres of North America and northern Europe generated radial mantle flow at depth. In our model, these currents, where flowing from west and east, faced each other below the northern Atlantic, joining together and upwelling. Numerical modeling of this process supports the development of dynamic topography leading to uplift of the sea-floor and inducing a regional geoid high. The upper mantle, being pumped from the deep mantle and rising to a few km shallower than average, may have contributed to larger asthenospheric melting, and to ridge centered excess magmatism, as observed in the Northern Atlantic. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2009GL041663 Does this not seem strange? The fourth dimension (time) must not be considered here... Quote 1. Introduction [2] The lithosphere generated by the Mid Atlantic Ridge (MAR) east of Greenland underlies the youngest (<60 Myr) and narrowest part of the Atlantic Ocean. This portion of the northern Atlantic shows three peculiar characters, 1: it is about 1–3 km shallower than the average mid-oceanic ridge (Figures 1a and 1b); 2: it displays diffuse positive gravity (>30 mGal) and geoid (>50 m) anomalies (Figures 1c, 1d, and 1f); 3: it is the seat of larger than average magmatic productivity, resulting in the thickest oceanic crust of the entire MAR, up to about 40 km below Iceland [Kaban et al., 2002]. The thickness of the Cretaceous-Early Cenozoic (pre-glaciations) oceanic crust in the northern Atlantic is rather 4–6 km in average [e.g., Shillington et al., 2006]. Fig.1 (a) Topography (data after ETOPO1, http://www.ngdc.noaa.gov/mgg/global/global.html); (b) elevation of the Mid Atlantic Ridge; the bathymetric distribution along the MAR shows a high in the northern Atlantic which is limited not only to the Iceland area but it extends ca 20° northward and 40° southward; (c) geoid anomaly along the Mid Atlantic Ridge (data after the EGM96 model, http://cddis.nasa.gov/926/egm96/egm96.html); (d) geoid height; notice how the northern Atlantic geoid high is located between the North American and Scandinavian ice bodies; (e) topography-bathymetry along the cross-section on the map to the left; (f) geoid height along the same section. The blue curves in panel Figure 1d show the borders of the ice bodies according to ICE-5G. The geoid is shallower along the eastern flank of MAR and the crest of the anomaly is offset to the east of the oceanic ridge. (g) Thickness in map and (h) cross-section in purple of the ice cap at the last glacial maximum (21 Kyr BP; data after the ICE-5G model [Peltier, 2004]). Mid-ocean ridges are shown as red lines.

Mario Dantas Posted July 30, 2022 Author #6 Share Posted July 30, 2022 (edited) I am disappointed! But not defeated... These are fresh new images. You kind of push me to it, in the sense that i am not forging anything. Just pointing similarities and oddities. I know that the chronological aspect is very important, but the truth is that ignoring time can yield very interesting results, imo. There is a clear anomaly in front of Gibraltar with so many similarities and nobody says a word. something interesting i just read about the north Atlantic anomalously shallow basin : Quote North Atlantic topographic and geoid anomalies: The result of a narrow ocean basin and cratonic roots?. King, Scott. (2005) There are anomalous, long-wavelength swells in the geoid and topography over the north Atlantic. The north Atlantic geoid swell is one of three prominent features in the global geoid after removing the effects of subducted slabs and glacial rebound. The swell is a 25- to 40-m peak-amplitude high and covers an area greater than 3000 × 3000 km. The north Atlantic ocean basin is anomalously shallow-by as much as 1500 m-compared to similarly aged ocean floors on the rest of the of the world's ocean basins. I use a series of calculations to investigate whether the geoid and topographic anomalies in the north Atlantic are consistent with the edge-driven convection hypothesis, with small-scale flow driven by the Greenland and Scandinavian cratons. I find that the small-scale convection pattern driven by the edge of a deep cratonic root can extend from the craton as far as 1000 km and upwell along a passive preading ridge. However, the north Atlantic geoid and topographic anomalies are difficult to reconcile with either a plume or an edge-driven convection mechanism. https://www.researchgate.net/publication/283810801_North_Atlantic_topographic_and_geoid_anomalies_The_result_of_a_narrow_ocean_basin_and_cratonic_roots Edited July 30, 2022 by Mario Dantas Simplification Link to comment Share on other sites More sharing options...

Mario Dantas Posted July 30, 2022 Author #11 Share Posted July 30, 2022 (edited) Quote A forked tongue is a tongue split into two distinct tines at the tip https://en.wikipedia.org/wiki/Forked_tongue As you can observe, the MAR exhibits a geological "forked tongue" (for lack of a better word). Why would that be the case? Maybe because upper mantle ascended from both sides of the Atlantic, meeting at the center? Moreover, the extremity point in the MAR where this happens (in the Google Earth) is a very strange detail in the geoid: It seems like the beginning of the north Atlantic anomaly. A yellow line (20) has been drawn in the geoid as if the tip reached both sides... Edited July 30, 2022 by Mario Dantas clarification Link to comment Share on other sites More sharing options...

Sir Wearer of Hats Posted July 30, 2022 #17 Share Posted July 30, 2022 So, let me get this straight - there was a geological event that shifted an island from rhe Atlantic, up to the North Sea. MD says that the sea floor shows signs of that movement. Are there any other locations where this has happened? Link to comment Share on other sites More sharing options...

Are you familiar with the Phaethon myth described in Plato' Critias? I propose that an impact or near collision took place in the Indian ocean (although a near collision would be difficult because the geoid tells us that something odd is happening at the lower mantle level). The Indian anomaly in the geoid is probably telling that some disturbance altered different layers of the upper and lower mantle, giving the appearance of an actual hole in the crust. After the impact the previous planetary system (was "erased" and changed by means of water ice, lava and violent continental crashes). I also propose that the earth slightly expanded (and of course later on ceased to expand), facilitating the fast movement of landmasses like India or Greenland. Seafloor spreading would then be a consequence of this event revealing itself like the proof that continents were indeed much closer within a ancient smaller radius earth. These geologic "convulsions" could be the answer as to why the peculiar topography of the northern MAR, or the important geoid anomaly, exist. When all the ice melted (except for Antarctica and Greenland) and sea level rose as much as 140 m as a consequence of intense heat consuming all the ice that would have existed in a snow ball earth planetary setting, with an important region being under the sun's influence, like polar regions as Greenland, with six months of continuous solar influence or midnight sun. The north pole was once under Greenland The surface of the planet would have been dramatically changed to become e.g. the Sahara desert, or the Himalayas, the Atlas range or the ice on top of Greenland. Why does this not work? The chronology does not favor my hypothesis, but could it be wrong? Several re heatings of the oceanic crust would have disguised its actual age, making it look much older... unimaginable crustal stresses would have taken place if an impact of this magnitude ever took place. The planetary mantle convection mechanism could have also started after this event, We know that the interference reached a great depth in the mantle and occupied a huge area.

Have you tried actually studying or reading about geology before you post this stuff? Hilarious. To tell you the truth, my work does not let me be more productive and understanding regarding these issues. There is simply no time for me to engage in When you say studying or reading, yes, but i am a freelancer since i read or study several geologic information available, but through a different "lens" so to speak. I am looking for evidences regarding Plato's account of the lost island. For instance, not being an expert is a very crucial element in my research, this is not my area of expertise... Nevertheless, i can assure you that reheating can alter the properties of the "lithospheric column"? Quote Thermal resetting Injection of extra heat into the lithospheric col- umn affects the depth-heat flow path no matter how it is done. The question is whether the reheated lithosphere could return to the original cooling path of the boundary layer within a reasonably short time. If it does, it must be at an age younger than its actual age. https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.590.5593&rep=rep1&type=pdf Quote Bearing in mind that hotspots are known to exist [30] and affect the thermal structure of lithosphere [31], a reasonable explanation for the discrepancy between the crustal and thermal ages is some type of reheating of the lithosphere.

Here is the typical brainless mutterings you post: "Maybe because upper mantle ascended from both sides of the Atlantic, meeting at the center?" The motion is from the MAR outward. Why can't you get even the trivial ideas right? And stop with the fake images. Annoying fake pictures is all you seem to have. You got me there... the motion must be outward from the ridge. I did not ponder enough about it. I have found this a week ago, when fiddling with the geoid and ocean floor topography. The southern extremity of the northern MAR anomaly starts there, and that "bifurcation" exists there for a reason. The Atlantic anomaly ends there, and from that point on the remaining MAR further south is within the "normal" average gravity for the ocean floor, i guess.
