Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

We present the first finding of continental crust-derived Precambrian zircons in garnet/spinel
pyroxenite veins within mantle xenoliths carried by the Neogene Hannuoba basalt in the …

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 …

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 …

Melt extraction from the partially molten mantle is among the fundamental processes
shaping the solid Earth today and over geological time. A diversity of properties and …

PRIMELT2. XLS software is introduced for calculating primary magma composition and
mantle potential temperature (TP) from an observed lava composition. It is an upgrade over …

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 …
