Doug Well I am starting to repeat myself and here I go again Summary of my big problems with subduction 1. The ocean basin plates are very rigid evidenced by the fractures and craggyness where they are being formed and the fact that they are hardened magma and granitic scum. The Tectonic plate theory calls for plates to be spreading, warping bending and converging. There is little evidence that this is happening. The ocean floors aside from the rises, seamounts, and continents are relatively smooth and show none of the bulging , cracking, waving, splitting, piling up, ect that would be evident if all the motions in the plates were taking place. 2. The shifting of the rise sections demonstrates that the source of the rise is connected to the rise..moves with the rise and not formed from a massive convection current system that dwarfs the continents and the puny ocean basins. 3. If the rise is caused by a convection current system how is it that a rise is linear in a north and south alignment…what would cause a consistent linear heat source on the interior of a sphere? 4. The floor has evidence of motion and swirls and streaks in the ocean basin floor…why would these features remain visible when the rise features disappear? 5. There should be a major pressure differential between the deep trench area and the higher rise area causing massive magma flows at the trench areas. 6.The continents would need to change shapes and sizes as they shrink and distend to accomidate the motions necessary to account for what appears by Plate Tectonics. BTW The convection system would work much better if visualised just opposite in flow. The flow comes up the sides of the continents and flows towards the middle area between them. Where the flow meets and goes downward it would naturally be between the continents. There is a backflow up the space between the downward laminar flows and this is what is heating and reprocessing the basin floor…..NAAAAAA. The basin core magnetics may be the best place to start..know where we can get our hands on any? Know anybody at Woods Hole Ma.? they have core material there I believe. Super New Year to Ya Doug!!
