These Canadian Rocks May Be the Oldest on Earth
- Researchers led by Jonathan O'Neil at the University of Ottawa confirmed that rocks in Canada's Nuvvuagittuq Greenstone Belt are 4.16 billion years old.
- This confirmation follows a 2008 study estimating the rocks at about 4.3 billion years, sparking debate due to differing dating methods and rock composition challenges.
- The team used two distinct radioactive decay methods, including samarium-146 to neodymium-142, making these rocks likely the only known Hadean eon crust today.
- Jesse Reimink from Penn State emphasized that the findings indicate these rocks are likely the Earth’s oldest known formations, underscoring their importance.
- If verified, this finding offers a rare window into Earth's first 500 million years and could improve understanding of early continental formation and life's origins.

Rocks in Canada may be oldest on Earth, dating back 4.16 billion...
The rocks could offer insight into Earth's primordial crust and the environment that gave birth to life. An obscure rock formation on the eastern shore of Canada's Hudson Bay may contain the oldest known rocks on Earth, a new study claims. The analysis dated the site's streaky gray rocks, part of an outcrop called the Nuvvuagittuq Greenstone Belt, to 4.16 billion years ago — meaning they're remnants from our 4.57 billion-year-old planet's earlie…
Scientists have identified what could be the oldest rocks on Earth, coming from a Quebec rock formation.
Canadian rocks may be the oldest on Earth
Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks — plains of streaked gray stone on the eastern shore of Hudson Bay in Quebec. But researchers disagree on exactly how…
Rocks in Canada's Quebec province found to be the oldest on Earth
Along the eastern shore of Hudson Bay in Canada's northeastern province of Quebec, near the Inuit municipality of Inukjuak, resides a belt of volcanic rock that displays a blend of dark and light green colors, with flecks of pink and black. New testing shows that these are Earth's oldest-known rocks. Read more at straitstimes.com.
