TORONTO, Sep. 30 (Agencies) -- Researchers find the world's oldest rocks, dating back to 4.28 billion years ago, on Canada's Hudson Bay shore in northern Quebec.
Termed 'faux amphibolite', the rocks are 250 million years older than any rocks known so far and might be evidence of ancient life form activity.
"It could be that the rock was formed 4.3 billion years ago, but then it was re-worked into another rock form 3.8 billion years ago. That's a hard distinction to draw," Co-author of the study and geology professor at McGill University, Don Francis explained.
