Rocks from the Hadean Eon, the first period in the geological timescale, have been dated in Québec. These are some of the ...

Scientists agreed the rocky outcrops in a remote part of Quebec, Canada, were ancient. But were they really Earth’s oldest? New research suggests they are.

This time, we collected intrusive rocks — called metagabbros — that cut across the Ujaraaluk rock formation, hoping to obtain independent age constraints.

Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name "Hadean" comes from the Greek god of the underworld, reflecting the extreme heat that likely ...

Most of the rocks there are metamorphosed volcanic rocks, rich in magnesium and iron. The most common rocks in the belt are called the Ujaraaluk rocks, meaning “big old solid rock” in Inuktitut.

We combined our field observations with petrology, geochemistry, geochronology and applied two independent samarium-neodymium age dating methods, dating techniques used to assess the absolute ages of ...
