Subduction-driven volatile recycling: A global mass balance
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 …

Earth's mantle composition revealed by mantle plumes
Mantle plumes originate at depths near the core− mantle boundary (~ 2,800 km). As such,
they provide invaluable information about the composition of the deep mantle and insight …

Deep-mantle krypton reveals Earth's early accretion of carbonaceous matter
Establishing when, and from where, carbon, nitrogen and water were delivered to Earth is a
fundamental objective in understanding the origin of habitable planets such as Earth. Yet …

An evaluation of the C/N ratio of the mantle from natural CO2-rich gas analysis: Geochemical and cosmochemical implications
The terrestrial carbon to nitrogen ratio is a key geochemical parameter that can provide
information on the nature of Earth's precursors, accretion/differentiation processes of our …

Deciphering a mantle degassing transect related with India-Asia continental convergence from the perspective of volatile origin and outgassing
Mantle degassing transect across different tectonic units within a plate convergent setting
has been well documented for oceanic convergent margins by systematic changes in …

Hydrothermal 15N15N abundances constrain the origins of mantle nitrogen
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 …

Primitive noble gases sampled from ocean island basalts cannot be from the Earth's core
Noble gas isotopes in plumes require a source of primitive volatiles largely isolated in the
Earth for 4.5 Gyrs. Among the proposed reservoirs, the core is gaining interest in the …

Identification of chondritic krypton and xenon in Yellowstone gases and the timing of terrestrial volatile accretion
Identifying the origin of noble gases in Earth's mantle can provide crucial constraints on the
source and timing of volatile (C, N, H2O, noble gases, etc.) delivery to Earth. It remains …

Halogen enrichment in the North American lithospheric mantle from the dehydration of the Farallon plate
A greater quantity of halogens (F, Cl, Br, and I) appear to be subducted globally than are
erupted at magmatic arcs, requiring either an increase in the mantle halogen budget through …

[HTML][HTML] Uncovering the xenon isotope composition of continental rift magmas: Insight from analysis of geothermal gases at Homa Hills, Kenya
We investigated geothermal gases from Homa Hills, a carbonatitic complex situated along
an adjacent branch of the Kenyan rift system, using neon, argon, krypton, xenon and …
