A study of the Nuvvuagittuq Greenstone Belt found that its rocks go back to the Hadean Eon, making them the ideal candidate for the oldest rock.

Canadian researchers said they'd found the world's oldest rocks in northern Quebec. The find was controversial. But after more than a decade of hard work, they believe they've really proven it and are giving scientists a new glimpse into Earth's early history.

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt in Quebec has long been known for its ancient rocks, but researchers disagree on exactly how old they are.
