Eastern China provides a precious opportunity to explore how subduction drives evolution of
the overlying continental lithosphere and to understand the fate of subducted plates. In this …

Magnesium isotopic fractionation during basalt differentiation is commonly thought to be
negligible at current levels of analytical precision. However, Mg isotopic variation of∼ …

Nephelinites, a highly alkaline volcanic rock type, have widely been thought to be formed in
a shallow lithosphere previously impregnated with phlogopite and/or amphibole. Here we …

This review describes the stable isotope character of the Earth's mantle, the 2900 km thick
silicate layer between the core and crust that comprises 67% of the Earth's mass and 84% of …

Melts and fluids derived from subducting/subducted oceanic lithosphere contribute
significantly to mantle compositional heterogeneity. Historically metasomatized lithospheric …

Carbonates subducted into the mantle alongside mafic material play a critical role in the
deep cycling of carbon. This recycled oxidized carbon strongly affects the physical …

The origin of EM1 (Enriched Mantle 1) reservoir, initially defined by the ocean island basalts
(OIBs) with extremely low 143Nd/144Nd and 206Pb/204Pb, has been long debated …

East-central China has experienced multi-stage evolution among different tectonic units;
thus the present geological structures are superimposed in a long history. But it is still …

Lamproites are rare mantle-derived peralkaline ultrapotassic rocks, and they are commonly
geographically associated with the ultramafic lamprophyres and kimberlites. Their unique …

The foundations of stable isotope geochemistry were laid in 1947 by Urey's classic paper on
the thermodynamic properties of isotopic substances and by Nier's development of the …
