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 …

The isotopic compositions of terrestrial hydrogen and nitrogen are clearly different from
those of the nebular gas from which the solar system formed, and also differ from most of …

The concentration of carbon in primary mid‐ocean ridge basalts (MORBs), and the
associated fluxes of CO2 outgassed at ocean ridges, is examined through new data …

The chemical characteristics of hydrothermal fluids in the Indian Ocean have been revealed
for the first time. A hydrothermal field (called the Kairei field), including active black smoker …

In order to better characterise mantle CO2/Nb-variability, we obtained and compiled major
and trace elements, content and isotope composition of both CO2 and water on two series of …

In order to better constrain the origin of volatile variability of mid ocean ridge basalt (MORB),
we have performed crushing analyses on 33 fresh basaltic glasses. Most samples originate …

Diamond, as the deepest sample available for study, provides a unique opportunity to
sample and examine parts of the Earth's mantle not directly accessible. In order to provide …

Carbon dioxide emissions from volcanoes are important parameters to constrain in order to
fully understand the Earth system, especially the effect of volcanic forcing on climate. The …

Knowledge of the subduction input flux of nitrogen (N) in altered oceanic crust (AOC) is
critical in any attempt to mass-balance N across arc-trench systems on a global or individual …

Lithium elemental and isotopic compositions of 33 glass and whole-rock samples from nine
oceanic island regions were determined to characterize the Li inventory of the deep mantle …
