Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

The roles of subduction of the Pacific plate and the big mantle wedge (BMW) in the evolution
of east Asian continental margin have attracted lots of attention in past years. This paper …

Although deep carbon recycling plays an important role in the atmospheric CO2 budget and
climate changes through geological time, the precise mechanisms remain poorly …

Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes
associated with deep cycle are in the order of 1012–13gC/yr and 1022–23g C, respectively …

Plate tectonic processes introduce basaltic crust (as eclogite) into the peridotitic mantle. The
proportions of these two sources in mantle melts are poorly understood. Silica-rich melts …

Results are reported of an exploration of mantle source lithology for intraplate magmas
using whole-rock and olivine phenocryst compositions. This analysis includes modern mid …

Recycled oceanic crust, with or without sediment, is often invoked as a source component of
continental and oceanic alkaline magmas to account for their trace-element and isotopic …

We document compositions of minerals and melts from 3 GPa partial melting experiments on
two carbonate-bearing natural lherzolite bulk compositions (PERC: MixKLB-1+ 2· 5 wt …

We present new experiments, combined with a re-evaluation of published data, to
characterize the topology of the silicate–carbonate two-liquid solvus in the five-component …

We performed reaction experiments between partial melt of volatile-free MORB-eclogite and
volatile-free fertile peridotite at 2.5–3GPa, 1375° C and 1440° C. The fraction of added …
