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 ...
Researchers have confirmed that a rare geological process called lithospheric dripping is pulling pieces of the Earth’s lower ...
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 ...
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 ...
Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey ...
“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 ...
Oceanic island hotspots — Hawaii and Iceland — are the final destinations of elemental isotopes from the beginnings of Earth, in concentrations found nowhere else on Earth’s crust. Until now, it was ...
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.
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 ...
New research deepens the understanding of Earth's crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic ...
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 ...
