These ancient metamorphic rocks called gneisses, found on the Arctic Coast, represent the roots of the continents now exposed at the surface. The scientists said sedimentary rocks interlayered in these types of rocks would provide a heat engine for stabilizing the continents. Credit: Jesse Reimink. All Rights Reserved.
