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 ...

One way to better understand the formation mechanism of such large-scale mantle heterogeneity, and thus potentially to verify the two contrasting mantle dichotomy models, is to examine the starting ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

Fig. 3: Patterns of incompatible trace elements in trapped melts in high-Mg olivine phenocrysts from komatiites, normalized to primitive mantle. An alternative explanation for the origin of ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

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 of the Chinese Academy of Sciences has made a significant ...

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 ...

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest ...

The research team led by Prof. WU Zhongqing from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences updated the pyrolite model by adding to it the lateral ...

The Ontong Java Plateau in the western Pacific Ocean is the largest oceanic plateau on Earth, and its formation mechanism has not been well understood.

Geochemists have investigated the volcanic rocks that build up the Portuguese island group of the Azores in order to gather new information about the compositional evolution of the Earth's interior.
