Great Britain may lay claim to some of the oldest rockers around with the Rolling Stones, but did you know that Canada has the “Satisfaction” of being home to some of the oldest rocks on earth? In fact, the oldest known rocks in the world can be found in Northern Quebec along the eastern shore of Hudson’s Bay. The area, known as the Nuvvuagittuq greenstone belt, houses rocks estimated to be 4.28 billion years old. That means these rocks were formed approximately 300,000 years after the formation of the Earth itself! Classified as “faux-amphibolites”, the rocks are beige or sugar brown (“Brown Sugar”?) in appearance and are providing geologists with new insights into the earliest stages of our planet. The previous record-holder for the oldest stone (no, not Bill Wyman) was 4.03 billion years old and found in the Acasta Gneiss rock outcrop in the Northwest Territories. However, the distinction of the oldest piece of our planet may go to a tiny zircon crystal found in western Australia. At only 200 x 400 microns, or around twice the diameter of a human hair, it is estimated to be 4.4 billion years old! So there you have it––some key discoveries which will tell us more about our Earth’s earliest years. By studying these amazing findings, geologists are learning more about the formation of our planet and its shifting land masses. Yes, “It’s Only Rock’n’Roll”, so to speak, and we like it!
