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 …

Tectonic or subduction erosion refers to the removal of upper-plate material from the forearc
at convergent margins. Subduction erosion has been suggested to represent a major …

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

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 …

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

Several methods have been developed to assess the thermal state of the mantle below
oceanic ridges, islands, and plateaus, on the basis of the petrology and geochemistry of …

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 …

Constraints on the composition of Mars principally derive from chemical analyses of a set of
Martian meteorites that rely either on determinations of their refractory element abundances …
