Tracking the final fate of subducting carbon is crucial to understanding global carbon cycles
and climate changes in the history of the Earth. Available geochemical tracers such as …

The number of studies using various stable isotope systems for tracing contamination
sources and various biogeochemical processes is rapidly rising due to the increased …

The terrestrial planets are depleted in volatile elements with respect to chondritic meteorites,
their possible building blocks. However, the timing, extent and origin of volatile depletion is …

The zinc (Zn) stable isotope system has great potential for tracing planetary formation and
differentiation processes due to its chalcophile, lithophile and moderately volatile character …

To better constrain the Ca isotopic composition of the Bulk Silicate Earth (BSE) and explore
the Ca isotope fractionation in the mantle, we determined the Ca isotopic composition of 28 …

Young (61 Ma) unaltered picrites from Baffin Island, northeast Canada, possess some of the
highest 3 He/4 He (up to 50 Ra) seen on Earth, and provide a unique opportunity to study …

Zinc and Cd isotope compositions are presented for a comprehensive suite of terrestrial
rocks to constrain the extent of Zn and Cd isotope fractionation during igneous processes …

Ocean island basalts (OIBs) are geochemically diverse in radiogenic isotopes, a feature that
is commonly ascribed to record the chemical heterogeneity of their deep-mantle source …

Geochemical characteristics of arc magmas reflect incorporation of subducted materials to
their mantle wedge sources in subduction zones. Subduction component addition has been …

Subduction at convergent margins introduces a range of sedimentary and crustal materials
into the mantle, providing the most dominant form of heterogeneity in the source of oceanic …
