The anomalous magnetic signal is consistent with an older tectonic event — the Alleghanian orogeny that formed the Alleghany - Appalachian Mountains when the supercontinent of Pangea was assembled.

The result of this collision was what is known as the Variscan orogeny, the raising of a mountain range along the North - South axis, which left the rocks with a secondary magnetic signal, adapted to the new magnetic field of the Earth.

He points out that this magnetic signal can be associated with large - scale processes of mountain formation, and how these ranges can be curved until they create structures known as oroclines: «With a rock sample, we can analyse a process that has occurred on the tectonic plate level; and, specifically, offers new data that allows us to discover how this orogeny or large Variscan range and its curvature occurred.

Also, it shows graphically the distribution of earthquakes by their magnitude and frequency that are caused by movement in the orogeny - a belt of the earth's crust involved in the formation of mountains.

Even such recently developed theories as plate tectonics are not referenced in papers discussing issues centrally related to it (eg, orogeny).
