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 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 study published on March 24 by two researchers from Yale’s Earth and planetary sciences department adjusts the timeline of continental crust formation to start approximately 650 to 750 million years ...

Curtin University researchers have used ancient crystals from eroded rocks found in stream sediments in Greenland to successfully test the theory that portions of Earth's ancient crust acted as 'seeds ...

A discovery of ancient rocks might finally answer one of the biggest questions in science: how did the Moon form? Researchers ...

Earth as we know it today looked drastically different several billion years ago. According to a paper recently published in the Proceedings of the National Academy of Sciences (PNAS), the composition ...

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 ...

James Webb Space Telescope observations show interstellar comet 3I/ATLAS has a 50-65 foot irradiated crust formed by billions of years of cosmic ray exposure. Research posted to arXiv indicates the co ...

Field image of the achondrite meteorite GRA 06128, found in blue ice of the Graves Nunatak region of the Antarctica during the ANSMET 2006/2007 field-season. Image courtesy of the Antarctic Search for ...

Researchers have used ancient crystals from eroded rocks found in stream sediments in Greenland to successfully test the theory that portions of Earth's ancient crust acted as 'seeds' from which later ...
