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.
