David Pratt has published a very interesting paper in the New Concepts in Global Tectonics journal with some very interesting conclusions.
Fossil magnetism in rocks can be affected by many factors, with the result that derived virtual magnetic poles for specific periods show a wide scatter.
The fundamental assumption that averaged palaeomagnetic poles approximately coincided with past geographic poles is unproved.
There is great scope for subjectivity in the selection, processing and interpretation of palaeomagnetic data, and this is reflected in inconsistent and often contradictory reconstructions of plate motions and true polar wander through time.
The major tenets of plate tectonics and the associated theories of continental fragmentation and assembly are contradicted by a wealth of evidence. The wrench-tectonic theory of large-scale polar wander and ‘minor’ plate rotations and translations, based on selected palaeomagnetic data, is also open to serious objections. Geological, geophysical, palaeontological and palaeoclimatic data do not require large-scale plate motion or polar wander; they point to nondrifting continents and stable poles, with vertical tectonic movements causing periodic changes in the distribution of land and sea.
PALAEOMAGNETISM, PLATE MOTION AND POLAR WANDER
New Concepts in Global Tectonics – NCGT JOURNAL March 2013
Overall, I very much agree with David Pratt’s conclusion that there “is great scope for subjectivity in the selection, processing and interpretation”. However, I would extend this statement to the Earth sciences in general – not just palaeomagnetism.
David Pratt’s paper has reached the attention of the news editor of the Society for Interdisciplinary Studies [SIS] who is relieved to know that the concept of an expanding Earth is fatally flawed.
This evidence alone, he assures the reader, contradicts the idea of continents drifting thousands of miles around the surface of the Earth. It is also fatal to the expanding Earth theorists – which is a bit of a relief.
Personally, I am very much aligned with the SIS news editor who is “warming to this subject and there is a long way to go”. Therefore, before the editor drafts “another post next week” it seems timely to introduce a couple of new perspectives [from my ongoing research] into the debate regarding the concept of the expanding Earth.
The roots of the expanding Earth concept trace back to Sir Francis Bacon [1561-1628] who noted “the similarity of shape of the opposing African and South American coasts” according to Warren Carey in his wonderfully subtitled book: Theories of the Earth and Universe – A History of Dogma in the Earth Sciences.
The earliest visual representation [that I have found on the internet] of the expanding Earth concept is from 1909 by Roberto Mantovani.
Roberto Mantovani’s illustration very much aligns with my own initial thoughts when I studied an atlas as a schoolboy and those old 1961 atlases are treasured processions.
Therefore, as a starting point [in this research] I performed a basic reality check using Wikipedia’s basic geological map.
Map of world geologic provinces
Overall, Roberto Mantovani’s concept appears to pass the geologic reality check.
The continental trio of South America, Africa and Australia seem to squeeze together horizontally. The US East Coast seems to line-up with North Africa and Greenland appears to connect Canada to Scandinavia.
A second level reality check is to see if this [subjective] visual matching is supported by a map of the seafloor.
Age of oceanic crust
Overall, Roberto Mantovani passes this second level reality check.
At this point the concept of an expanding Earth is looking good, but, as David Platt has so eloquently explained there are many problems with the current expanding Earth theories – let alone the mainstream excuses for plate tectonic.
However, the expanding Earth explanations that I have read are very superficial insofar as they concentrate upon the surface of the Earth. This is missing the forest for the trees because 99% of any expansion [if it exists] is not happening on the surface of the Earth. The majority of any inflation must occur in the interior of the Earth.
Therefore, if the Earth is inflating then there should be some record of outgassing that matches the seafloor expansion record.
Following this line of inquiry produces some very interesting results.
The 1966 illustration of the seafloor age includes a scaled key which provides a guide to the ages and relative growth rates – as graphed below.
Evidently there have been two big waves of seafloor spreading that should be associated with planetary outgassing and [possibly] expansion.
Interestingly, the high level summary graph of the oxygen content of the Earth’s atmosphere also depicts two big waves of oxygen outgassing.
Although the timelines are different the patterns are very similar.
Personally, I have more faith in the pattern than the dating [in both diagrams].
Oxygen content of the atmosphere over the last billion years.
Another, cross check on the planetary outgassing [and any expansion] should also be reflected in the Earth’s biodiversity [as currently understood from the fossil record].
Biodiversity as shown by the fossil record
The very remarkable feature in the biodiversity graph is the rise and gradual decline in biodiversity than continued until about 200 million years ago.
However, the biodiversity suddenly takes-off exponentially when the seafloors start spreading 180 million years ago. This is very indicative of an expanding Earth with new habits, extended habits and new climate zones.
Personally, I perceive there is very good high level support for the concept of an inflating Earth driven by planetary outgassing of oxygen and hydrogen [mainly in the form of water – H2O].
However, many people will perceive things differently.
