....yes africa & s. america once joined as part of a super-continent, but their separation is through adding new lava along the spreading center (atlantic ridge)...
So the profile of the Andes is not similar?? You fail to address this point. (See p. 107 thru 118).
Despite the arguments put forward against this theory, the undeniable fact remains that there is a similarity between each of the geologic features I have mentioned (bathymetric imagery also supports this); there is a definite area of debris which looks to have been dispersed westwards from the site of the suggested exit event (click on the Himalayas to see it on this map and then look westwards from the Tibetan Plateau), and there is evidence of corresponding damge to the Earth's crust ..exactly where one would expect to find it following such an event.
Clearly, the Mid Atlantic Ridge is the reult of Africa and America seperating - you won't find many arguments against that - but what initiated the separation? And, why is the said separation so similar in shape to the Andes mountain range?
There are other clues visible on the above map which add weight to the theory, all of which complement the suggestion that the formation of Andes was the catalyst for the widening of the Atlantic Ocean basin. Trace the shape created when one follows the geological features throughout the route from Swaziland (on Africa's south coast) up through Mozambique and along the Rift Valley; along the Red Sea and then westawrds along the Meditteranean Sea back towards the Pillars of Hercules and the Atlantic.
The Rift Valley is clearly a result of tremendous forces that have attemptied/are attempting to split the surface of the Earth along its length, as is the Red Sea. Given what is included elsehwere in the theory about the tensions created by the Impact and Exit Event on the surface of Earth it can reasonably be assumed that any such tensions - released or otherwise - would leave some evidence of its origin.
Re: the profile created by tracing the outline I mentioned above. What you will find is that the profile created by the west coast of Africa, the Rift Valley, the Red Sea and the Mediterranean Sea is a profile that is reminiscent to that of the overall coastline of South America.
This would appear to be a logical outcome to the series of corresponding splits, similar in profile that would have been generated by the fallout from the impact event.
Further to the east, there is evidence of another 'split' in the Earth's crust. This lies upon an axis that suggests it was also created via the same event as that which created the Mid Atlantic Ridge etc, albeit on an understandably diminishing scale. This is referred to as the Persian Gulf (further info on this is on p. 114 of the pdf) .
Finally, where along the Mid Atlantic Ridge is the Gulf Of Mexico respresented? If the Mid Atlantic Ridge is one continuous formation that runs the north/south length of Earth (which it is), then why isnt the profile of Gulf of Mexico apparent anywhere along the ridge (p. 85-89)?
The ONLY explanation for this must surely be that the geologic anomaly that is the Gulf of Mexico has a different origin than the Mid Atlantic Ridge.
...the impact event?
