What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

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

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. The oldest rocks in Australia, which are ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

Tonalite-trondhjemite-granodiorite suites, dominating Earth’s early continental crust, likely formed by partial melting of hydrated metabasalt, but the specific conditions and mechanisms remain poorly ...
