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 ...

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 ...

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 ...

The Earth’s crust has a highly evolved chemical composition and is one of the most accessible parts of our planet for studying geological history . However, current crustal formation models are based ...

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 ...

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

Early crust on Mars may be more complex than previously thought—and it may even be similar to our own planet's original crust. The Martian surface is uniformly basaltic, a product of billions of years ...
