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 …

Subduction erosion occurs at all convergent plate boundaries, even if they are also
accretionary margins. Frontal subduction erosion results from a combination of erosion and …

Subduction erosion, which occurs at all convergent plate boundaries associated with
magmatic arcs formed on crystalline forearc basement, is an important process for chemical …

Processing of the oceanic lithosphere in subduction zones gives rise to arc magmatism, and
strong compositional links exist between trench input and arc output. Here we address the …

Subduction zones are both the source of most new continental crust and the locations where
crustal material is returned to the upper mantle. Globally the total amount of continental crust …

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

We review data and recent research on arc composition, focusing on the relatively complete
arc crustal sections in the Jurassic Talkeetna arc (south central Alaska) and the Cretaceous …

Subduction erosion shapes at least half of the world's convergent margins. However, its
rates, and modes as well as spatial and temporal variation are poorly understood. Based on …

The formation of the Earth's continents is enigmatic. Volcanic arc magmas generated above
subduction zones have geochemical compositions that are similar to continental crust …

Continental arcs, such as the modern Andes or the Cretaceous Sierra Nevada batholith, are
some of the highest topographic features on Earth. Continental arc volcanoes may produce …
