A study published in Nature on 2 April reveals that Earth's first crust, formed about 4.5 billion years ago, probably had chemical features remarkably like today’s continental crust.

This discovery alone would be an impressive find. If you know a sample of rock is only one step removed from Earth's first crust, terra primum, then "by studying the makeup of these rocks, you ...

EARTH is just shy of 4.6 billion years old and roughly a couple hundred million years later the planetary blob began to cool enough for it to form its first crust.

Our planet was born around 4.5 billion years ago. To understand this mind-bendingly long history, we need to study rocks and the minerals they are made of.

But unlike modern oceanic crust, which typically lingers for less than 200 million years before getting recycled into Earth’s interior by plate tectonics, the precursor crust survived for more ...

A close-up of 2.7 billion-year-old granite from the Hudson Bay. These rocks are apparently the second generation of rocks on Earth: Their parent rock was around 4.3 billion years old.

Ancient rocks deep in Earth’s crust are producing much more hydrogen gas than previously thought — a situation on a par with conditions near hydrothermal vents, which host thriving ecosystems ...
