Documenting the mass flux through convergent plate margins is important to the
understanding of petrogenesis in arc settings and to the origin of the continental crust, since …

Oblique aseismic subduction below western Panama and southeastern Costa Rica has
produced Recent arc-related volcanism. The aseismicity is probably related to the …

Subducted sediments play an important role in arc magmatism and crust–mantle recycling.
Models of continental growth, continental composition, convergent margin magmatism and …

Arc magmas and the continental crust share many chemical features, but a major question
remains as to whether these features are created by subduction or are recycled from …

AT ocean trenches, sea-floor sediments may either be scraped off the subducting plate, or
accompany it into the mantle. Some of the subducted sediment may then be recycled to the …

Volcanic eruptions are the clear and dramatic expression of dynamic processes in planet
Earth. The author, one of the most profound specialists in the field of volcanology, explains …

We investigated the spatial-temporal distribution and the major, trace, and rare earth
element geochemistry, U-Pb zircon geochronology, and isotope geochemistry of mafic dike …

Geothermal fluids and volcanic emissions are important sources of arsenic (As), resulting in
elevated concentrations of As in ground-, surface-water and soil, which may adversely affect …

Carbon and other volatiles in the form of gases, fluids or mineral phases are transported
from Earth's surface into the mantle at convergent margins, where the oceanic crust …

Subducting oceanic crusts release fluids rich in biologically relevant compounds into the
overriding plate, fueling subsurface chemolithoautotrophic ecosystems. To understand the …
