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 ...

Deep beneath the Pacific Ocean, geophysicists have uncovered enigmatic structures in the Earth’s mantle that challenge existing scientific theories. Using advanced seismic imaging, researchers from ...

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 ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same. A ...

“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 ...
