I wonder what a similar study might show here in Canada, seeing as how much of the country is hard igneous rock with, in a few areas, some sedimentary overlay....
For a $20M investment, mapping deep geology related to the breakup of Pangea has located:
1. Regions where the risk to power grids from solar storms is 1000x higher!
2. New targets for critical mineral exploration
Seems like a pretty cheap date?
Sensor array traces how rocks conduct electricity, exposing ancient continental fragments, mineral targets, and grid hazards
