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.

Discovering Earth’s geological structure and mineralisation at 200 km depth using Seismic tomography. Currently accepted Plate Tectonics paradigms need questioning! APPLICATION OF DISRUPTIVE INNOVATION. Part 9.

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.
