A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into
subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth's history …

Characteristics of cold seeps at different geologic settings are the subject of this review
primarily based on results of the Research Consortium SFB 574. Criteria are drawn from …

The subducting oceanic lithosphere may carry a large amount of chemically bound water
into the deep Earth interior, returning water to the mantle, facilitating melting, and hence …

Some 300–600 Tg of volatiles are globally vented each year by arc volcanism. Such arc gas
emissions have contributed to past and present-day evolution of the Earth atmosphere and …

Marine cold seeps are windows into different depth levels of the submerged geosphere.
Subduction zones and organic-rich passive margins host most of the world's cold seeps. The …

Abstract Ilopango volcano (El Salvador) erupted violently during the Maya Classic Period
(250–900 CE) in a densely-populated and intensively-cultivated region of the southern …

Volcanism has affected the environment of our planet over a broad range of spatial (local to
global) and temporal (< 1 yr to 100s Myr) scales and will continue to do so. As well as …

Mafic eclogites are found in many orogens as lenses embedded in quartzofeldspathic
migmatites. These high‐pressure relics are interpreted either as remnants of ancient sutures …

This work presents a new database of SO2 and CO2 fluxes from the Southern Central
American Volcanic Arc (SCAVA) for the period 2015–2016. We report∼ 300 SO2 flux …

The fate of subducted crustal nitrogen (N) in modern-style subduction zones remains hotly
debated from nearly complete return to the surface via arc volcanoes to net ingassing into …
