Earth’s evolution. Seismic tomography at 550 km depth shows major discontinuities (450-650 km depth). These are probably the tops of Ultra-Large Igneous Provinces (ULIPs) formed from the earliest huge impacts. It is suggested that these impacts were associated with the planet-sized bolide impact 4.56 billion years ago that spalled off the moon.
Mineralisation. The cross-section shows strong structural pathways from the core, at 5,000°C to the surface, at 20°C. The core is where I believe the mineralising fluids forming the mines ascended.
Where to from here? If my EagleEye system (or similar) were used by the general geoscience industry to get the detailed structural geology of the earth, from the surface to the core, a huge advance in our knowledge of Earth, and mineralisation, would occur.

Seismic tomographic research under North and South America, Africa and Eastern Europe from 170 – 550 km depth shows giant ring structures. It is suggested these formed before or during the Late Heavy Bombardment from 4.1 to 3.8 billion years ago. They exist from the surface down to at least 600 km depth. These relatively undeformed rings occur in the supposed mobile mantle. So, Earth down to 600 km depth is not mobile and so the evolution of Earth by earth-wide Plate Tectonics cannot be correct and needs revision.

To navigate my geotreks.com.au website go to ARCHIVE in the top menu bar.
Introduce the concept of DISRUPTIVE innovation. The only published Earth-wide research that is currently available in tomography and various other data sources are colour contour based 3-D models, and not structural geology models. The structural geology outlined on the Earth seismic tomography at 200 km depth are Earth-scale (they go over the whole earth) .
The diamond mines follow large rings in North America, South America and Africa. They always lie in the dark areas between the rings. They also follow the large northerly trending arcs and follow EW strong linear structures.. Thus these structures form the basis for worldwide diamond exploration targeting.
