Earth’s oldest rocks found in Quebec

Canadian researchers have discovered the oldest rocks in the world.

The remnants of the Earth’s early crust are 4.28 billion years old and were found in a belt of ancient bedrock in northern Quebec, along the eastern shore of Hudson Bay.

They have been around since roughly 300 million years since the planet was formed 4.6 billion years ago, says Jonathan O’Neil, a doctoral candidate at McGill and the lead author of a paper published in Friday’s edition of the journal Science.

They offer scientists a glimpse of the distant past, and what the young Earth looked like. They suggest that continents formed very early in the Earth’s history, says Richard Carlson at the Carnegie Institution in Washington, a member of the team that analyzed the rocks and a co-author on the paper.
