Rocks of Mesozoic age in Minnesota tell the story of two major marine trangressions (or sea level rises): one during the Jurassic Period (roughly 200 million years ago) and one during the Cretaceous Period (roughly 100 million years ago).

The results defined that ...Early Cretaceous extension and magmatism in the eastern NCC were in essence the surface expressions of deep thermo-mechanic processes, which were possibly associated with a big mantle wedge system resulting from rollback and retreat of the subducting paleo-Pacific plate [1, 10].The Appalachian Mountains were formed when colliding tectonic plates folded and upthrusted, mainly during the Permian Period and again in the Cretaceous Period.
