Recently, scientists confirmed rocks from the Nuvvuagittuq Greenstone Belt are about 4.16 billion years old using two radioactive dating methods. The Nuvvuagittuq Greenstone Belt is on the eastern shore of Hudson Bay in Quebec, Canada, known for its ancient rock formations. These rocks might be the oldest on Earth, rivaling the Acasta Gneiss Complex, which is about 4 billion years old. Radiometric dating helps track radioactive decay to estimate rock age. Most rocks from Earth’s early history were destroyed, making these samples rare.
