This webinar covers in detail many of the topics of the Earth’s mineralising systems and global exploration to be discussed at the 6th vInternational Archaean Symposium (25-27th July, Fremantle) and would be a magnificent ‘foil’ to the ‘incremental – accepted – mainline’ talks that I can see on the program.
Over the last 30 years successful experimentation by the author, with structural recognition and definition programs to look into Earth’s geological structure, developed into the EagleEye system. We can now obtain ‘MRI’ type Earth structural geology from the surface to Inner Core.
New Earth mineralising system overview.
Everywhere Earth has been examined 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 as the plate margins extend subvertically to the core. Thus, there are pressure release paths from the core to the surface for mineralisation See geotreks.com.au and my AusIMM mineralisation webinar (https://www.youtube.com/watch?v=bFurQYhWjyk ) for many papers and images supporting the above.
It is suggested that the mass of the giant subductions around the original Theia Impact in the Pacific Ocean are ‘scraped off’ by the hotter Outer Core which is then pressurised releasing heat and mass back up to the surface. This over-pressuring and subsequent release of the outer core most likely causes the cycles of mineralisation on Earth.
It is suggested the first major global tectonism occurred at 3 – 2.6 Ga forming the first worldwide mineralisation events. Figure 1 – A, B and C show that subvertical surface mineralisation structures can be followed down right to the outer core. This indicates that some mineralisation, heavy metals in particular, may have been derived straight from the core. Inset D suggests that structures from this deep geology can be used to target surface mineralisation in the Yilgarn. The ability of EagleEye to define geological structure, at all scales, from geophysical and geographical data is new and gives a much needed, completely new dimension to exploration exploration targeting.
Once again view right through the video to get an idea of these totally new mineralisation and exploration paradigms;
