Volatile elements (water, carbon, nitrogen, sulfur, halogens, and noble gases) played an
essential role in the secular evolution of the solid Earth and emergence of life. Here we …

We comprehensively compile and review N content in geologic materials to calculate a new
N budget for Earth. Using analyses of rocks and minerals in conjunction with N–Ar …

Study of metamorphic suites directly representing the deep subduction of altered oceanic
crust and sediments can help elucidate the geochemical evolution of the forearc-to-subarc …

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 …

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 …

Early in Earth's history, the Sun provided less energy to the Earth than it does today.
However, the Earth was not permanently glaciated, an apparent contradiction known as the …

This review gives an overview of the estimates of volatile emissions from arc and mid-ocean
ridge volcanoes to the atmosphere and hydrosphere with particular focus on H2O, CO2, N2 …

Nitrogen is the main constituent of the Earth's atmosphere, but its provenance in the Earth's
mantle remains uncertain. The relative contribution of primordial nitrogen inherited during …

Metamorphosed Jurassic oceanic sediment in the Italian Alps experienced peak P–T
conditions (1.5–3.0 GPa; 330–550° C) similar to those experienced by sediments …

Earth's carbon cycle is strongly influenced by subduction of sedimentary material into the
mantle. The composition of the sedimentary subduction flux has changed considerably over …
