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 ...

A recent studypublished in Naturepresents compelling evidence of ancient planetary material buried deep within Earth’s mantle. Researchers have uncovered two massive dense structures beneath Africa ...
“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 ...
