Nuvvuagittuq Greenstone Belt is a series of rock formations in Northern Canada, on the eastern shore of the Hudson Bay. They may be up to 4.4 billion years old. The belt is one of the oldest rock formations on Earth, but there is dispute about its actual age. 3,770 million years ago is accepted by others.[1] The rocks have been metamorphosed by later geological events.
