Liens entre les glaciers et la "Great Unconformity"



Extrait de l'article:

New research provides further evidence that rocks representing up to a billion years of geological time were carved away by ancient glaciers during the planet’s “Snowball Earth” period, according to a study published in Proceedings of the National Academy of Sciences.

The research presents the latest findings in a debate over what caused the Earth’s “Great Unconformity”—a time gap in the geological record associated with the erosion of rock up to 3 miles thick in areas across the globe.
