The gold standard for determining the age of ancient rocks is measuring the radioactive decay of isotopes of uranium into lead in minerals known as zircons. But not all rocks contain zircons, so ...

In 2008 scientists reported that rocks in Canada were the world’s oldest. New data appear to confirm this contested claim ...

Researchers instead used samarium neodymium (Sm-Nd) dating, a method that takes advantage of radioactive decay of samarium-146 and samarium 147 into neodymium-142 and neodymium 143, respectively. The ...

Potassium-Argon dating is similar to Carbon 14 dating because it uses radioactive decay, measuring the rate of change from an ...

Scientists employed two established dating techniques, which measure the decay of radioactive elements, to arrive at the refined age. The discovery significantly contributes to understanding Earth's ...

A belt of swirly, stripey rock in the northeast reaches of Canada looks like it contains some of the oldest minerals ever ...

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

(Reuters) -Along the eastern shore of Hudson Bay in Canada's northeastern province of Quebec, near the Inuit municipality of ...

If the new age of these Canadian rocks is solid, they would be the first and only ones known to have survived Earth’s earliest, tumultuous time.

Rocks older than 4.03 billion years could shed light on Earth's earliest geological history, but they're incredibly rare.

In 2008, researchers reported that these rocks dated back 4.3 billion years 2, a claim that other scientists contested. Work ...

A recent study has uncovered that giant magnetar flares may play a key role in generating rare elements such as gold and ...
