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 proposed a “potential oxygen fugacity” parameter to directly compare the fO 2 characteristics of melts formed at different depths. The oxygen fugacity (fO 2) of the mantle controls the ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

A research team Led by Professor WU Zhongqing from the School of Earth and Space Sciences at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences（CAS）, in ...

“Where is the impactor?” The question, raised during a planetary science lecture back in 2019, struck a chord with geophysicist Qian Yuan. The answer, he suspected, was neither in an asteroid belt nor ...

Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science ...
