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 …

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 …

More than 50 per cent of the Earth's upper mantle consists of olivine and it is generally
thought that mantle-derived melts are generated in equilibrium with this mineral. Here …

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 …

There is no consensus on the processes responsible for near-coeval formation of Archaean
continental crust (dominantly tonalite–trondhjemite–granodiorite: TTG), greenstone belts …

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 …

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 …
