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 ...

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 ...

Researchers have confirmed that a rare geological process called lithospheric dripping is pulling pieces of the Earth’s lower ...

A new study involving an international team of researchers has found that the evolution of land plants caused a sudden shift in the composition of Earth's continents. The discovery was made by linking ...

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 today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research finds. This early rocky shell featured chemical signatures previously ...

Earth's continents have been leaking nutrients into the ocean for at least 3.7 billion years, new research suggests. When you purchase through links on our site, we may earn an affiliate commission.

“To see a world in a grain of sand,” the opening sentence of the poem by William Blake, is an oft-used phrase that also captures some of what geologists do. We observe the composition of mineral ...

Scientists show that remnants of the roots of Earth's first crust are still present in the terrestrial mantle and contribute to magmas erupted at the surface over Earth's history. In an international ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...
