This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read full ...

Interdisciplinary in scope, The Earth's Mantle is a comprehensive overview of the composition, structure and evolution of the mantle layer. Striking a balance between established consensus and ...

The mantle can, rarely, be sampled directly, as in the study discussed in the News & Views article on page 215 of this issue. But its composition can also be inferred from basaltic rocks in the ...

Current estimates range anywhere from 30 to 100%, implying that much remains unknown about the processes that affect the composition and evolution of the Earth's mantle. With the osmium isotopic ...

By probing chemical processes observed in the Earth's hot mantle, Cornell scientists have started developing a library of ...

the interaction of the Earth's mantle with other major reservoirs (continental crust, core), and the estimation of the bulk composition of major Earth reservoirs, to more localized aspects of melt ...

The oxygen fugacity (fO 2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity ...

Volatiles play significant roles in modifying the composition of sub-continental lithospheric mantle, in the formation, ascent and emplacement of kimberlites, and in diamond preservation. Despite of ...

China's Chang'e-6 robotic spacecraft in June made history by retrieving the first surface samples from the far side of the ...
