Diamond-encrusted rock samples found on Canada’s Baffin Island have led geologists to discover a ‘lost’ fragment of North Atlantic Craton (NAC). The NAC is an ancient part of Earth’s continental crust that stretches from Scotland to Canada’s Labrador, deep underground. Researchers believe NAC is about 2.7 billion years old before its continental plate broke into fragments 150 million years ago.
