Talk Description
With EagleEye (using pattern (structural) recognition and definition software) we can now obtain imaging (similar to magnetic resonance imaging, MRI) of Earth’s structural geology from the crustal surface to Inner Core. The results change the fundamental precepts of Plate Tectonics. Wherever Eagle-Eye has examined Earth there is evidence of a brittle geological lithospheric environment down to the Outer Core. There is also abundant evidence of ‘continental scale’ block movement. This block movement is generated from the core to the surface because the plate margins extend subvertically to the core. There is no evidence of a mobile mantle or ‘lava-lamp’ type plumes. This new structural geology suggests the current model of ‘Plate’ Tectonics is flawed and a new ‘Block’ Tectonics model is proposed. Earth Evolution. It is suggested that early Earth was much colder (space dust at – 100 °C) than the current semi-molten model and re-formed as a solid after the Theia impact at 4.47 Ga spalled off the moon. There is strong evidence of giant impact structures (formed during the Extended Late Heavy Bombardment, ELHB, 4.47 – 3.6 Ga) penetrating down to the seismic discontinuity at 600 km depth. Many of these ring structures are still undeformed suggesting much of Earth has not undergone major tectonism in the last 3.6 Ga. It is suggested that the base of the giant subductions around the original Theia Impact in the Pacific Ocean are ‘scraped off’ by the hotter Outer Core, which is thus pressurised, releasing heat and mass back up the internal plate margins to the surface. It is suggested the first major tectonism occurred at 3 – 2.6 Ga forming the first worldwide mineralisation events.
