I have wondered how the Chicxulub asteroid impact could have generated a large tidal wave that swept up through the central parts of North America – the primary direction of oceanic upheavals around the globe. That is, in a model that embraces ocean spreading, a central part of Plate Tectonics. In other words, in the Pangea model the Atlantic was not very wide. Not only that – it was not very deep. On top of that it is claimed a shallow sea covered what is the chalk geology of western Europe. This is hundreds of feet thick in places. How did it get that deep – and why is it pristine white in colouration. Was it freshly laid down?
I came across an article at www.ncgtjournal.com … from March 2014 [see back issues index] – ‘Origins of Oceans: Spreading versus Primary Ocean Models‘. The idea that oceans spread gradually, and slowly, over a very long period of time, opening up and eventually forming a large expanse of water, is central to Plate Tectonics. The Atlantic plays a major role in this as the expansion is supposed to originate at the Mid Atlantic Ridge. This is of course a long way from Chicxulub – although it is a midway point between Chicxulub and the Gulf of Guinea where another part of the asteroid impacted. It was imagined that the magnetic stripes on the seafloor represented some kind of evidence of plate movement – and they can actually be tied down to estimated date ranges on the supposition of spreading seafloor dynamics. Of course, those magnetic stripes may have been caused by an otherwise unknown process, and would have had no date attached to them if the ocean had already been largely intact. A lot of water from the Caribbean and Atlantic was required to create the Mid Continent Seaway. Even more so if the seaway was in fact the tidal wave generated by the impact and had a relatively short life span. It certainly killed a lot of wildlife as it is the most prospected region for the remains of dinosaaurs in North America. They are very often found in a heap of broken bones – although some specimens are found almost intact, but buried in silt and sand and sediments. How much water was in the Atlantic/ Caribbean in the Cretaceous period? In Plate Tectonics the ocean would only have been narrow – but was it deep? The two ideas seem to contradict each other. Not in mainstream of course as the sea way is thought to have existed for thousands if not millions of years.
According to the seafloor spreading model the serpentine mantle, oceanic crust, and sedimentary cover, form a uniform vertical column. However, the ocean floor progressively became younger as the seafloor spread. That is why its oldest parts are found closest to the continents and its younger parts closest to the Mid Atlantic Ridge. That is the theory. Hence, the age of rocks composing the modern ocean basin should change horizontally – not in a verticle direction. No explanation for this has even been presented by seafloor spreading proponents, we are told. Deep sea drilling seems to say otherwise. The age of oceanic crust determined by magnetic stripe anomalies is not supported by stratigraphic data.
