But due to their ingrained beliefs, plate tectonicists tend to ignore the growing evidence that there used to be large, now submerged, continental landmasses in the present oceans – landmasses that are completely ignored in imaginative reassemblies of today’s supposedly drifting continents.
Several geoscientists have called for a major effort to drill the ocean floor to much greater depths to verify whether, as the data available already suggest, the basalt layer that is currently labeled ‘basement’ conceals more ancient sediments below it.
Francis Mazière thought that the legendary lost continent of Hiva might have been a long continental ridge (the East Pacific Rise).
As explained below, growing evidence is emerging that far larger areas of the Pacific Ocean were once land.
Most plate tectonicists believe that chains of oceanic islands and seamounts in the Pacific are the result of the Pacific plate moving over ‘hotspots’ of upwelling magma.
The continents and oceans are covered with a network of major structures or lineaments, many dating from the Precambrian.Successive ice ages during the Pleistocene have lowered sea level by at least 100 m and possibly far more at times, and Easter Island would then have been larger than it is today.According to the ruling geological paradigm of plate tectonics, Easter Island has never been part of a sunken continent.The island is believed to be the summit of an immense mountain formed by the outpouring of molten volcanic rock from the seafloor.It rests on a submarine platform some 50 or 60 m below the ocean’s surface, but 15 to 30 km off the coast, the platform ends and the ocean floor drops to between 18 m.Plate tectonicists have had to resort to the far-fetched notion that soft ocean sediment can slide smoothly into a subduction zone without leaving any significant trace.An alternative view of Benioff zones is that they are very ancient fractures produced by the cooling and contraction of the earth, and currently represent the deformation interface between the uplifting island arc/continental region and the subsiding ocean crust and mantle.But whereas 80,000 km of midocean ridges are supposedly producing new crust, there are only 30,500 km of trenches and 9000 km of ‘collision zones’ – i.e. If subduction was really happening, vast amounts of oceanic sediments should have been scraped off the ocean floor and piled up against the landward margin of the trenches.However, sediments in the trenches are generally not present in the volumes required, and they do not display the expected degree of deformation.These crucial facts – which go largely unmentioned in modern geological textbooks – render the large-scale lateral movement of individual ‘plates’ impossible.Plate tectonics claims that new ocean crust is constantly being created by upwelling magma at ‘midocean’ ridges (including the East Pacific Rise) and subducted back into the mantle along ocean trenches, mostly located around the Pacific Rim.
