Researchers used thermochronometric data from four North American locations to determine the cause of the “Great Unconformity” — a massive loss of rock about 700 million years ago. Credit: Kalin McDannell

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.
