Short summary
With over three-quarters of Greenland hidden beneath ice, direct geological observation is nearly impossible. Magnetic mapping provides now a passive and efficient geophysical method to image hidden subsurface features, offering a powerful tool for tectonic analysis and geological modeling in otherwise inaccessible regions. We have now developed a new magnetic anomaly map of Greenland using state-of-the-art technology providing new insight into Greenland's buried geology.
