Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

We extracted all volcanic arc rock analyses calculated to be in equilibrium with mantle
olivine from the global georoc database. This results in 938 primitive melt compositions from …

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 …

Experiment and observation have established the centrality of oxygen fugacity (f O 2) to
determining the course of igneous differentiation, and so the development and application of …

Arc magma acquires continental crust-like trace element signatures through selective
recycling of incompatible elements from the subducted slab. The long-standing model of …

Convergent plate boundaries are key sites for continental crustal formation and recycling.
Quantifying the evolution of crustal thickness and paleoelevation along ancient convergent …

Hydrous arc magmas are produced when water-bearing materials from subducted oceanic
plates are transported to the mantle beneath volcanic arcs, though the mechanism of mass …

Continental arc magmas supply the ore-forming element budget of most globally important
porphyry-type ore deposits. However, the processes enabling certain arc segments to …

A first-order observation of convergent margin volcanism is that continental arc
stratovolcanoes have substantially elevated incompatible element abundances and notable …
