Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean ...

A new way to calculate the age of Earth's crust has been developed by researchers in the UK. A new way to calculate the age of Earth's crust has been developed by researchers from the University of ...

What can craters on Saturn’s largest moon Titan teach scientists about its methane reservoirs? This is what a recent study ...

Formation of blueschist determined by changes to the chemical composition of oceanic crust One of the big mysteries in the history of the Earth is the emergence of plate tectonics. When exactly did ...

A study suggests that Earth's crust in the Hadean eon, more than 4 billion years ago, was more similar to the modern continental crust than previously thought, with implications for the timing of ...

Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

The continents are archives of Earth's evolution. Analysis of the isotopic signature of continental crust globally suggests that buoyant, silicic continents began to form 3 billion years ago, possibly ...
