In order to better determine the behavior of CO 2 relative to incompatible elements, and
improve the accuracy of mantle CO 2 concentration and flux estimates, we determined CO 2 …

Processing of the oceanic lithosphere in subduction zones gives rise to arc magmatism, and
strong compositional links exist between trench input and arc output. Here we address the …

Understanding magmatic processes such as crystallization and melting recorded in natural
samples requires calibration of mineral–melt trace element partition coefficients (D) and their …

Molybdenum isotopes have emerged as novel tracers for high-temperature igneous and
metamorphic processes. The debate remains to what extent different subducted slab …

The Eastern Lau Spreading Center (ELSC) is the southernmost part of the back-arc
spreading axis in the Lau Basin, west of the Tonga trench and the active Tofua volcanic arc …

The composition of the convecting asthenospheric mantle that feeds the mantle wedge can
be investigated via rear-arc lavas that have minimal slab influence. This “ambient mantle …

Multiple sulfur isotopes were measured in metal sulfide deposits, elemental sulfur, and
aqueous hydrogen sulfide to constrain sulfur sources and the isotopic systematics of …

Deep-sea hydrothermal vents are populated by dense communities of animals that form
symbiotic associations with chemolithoautotrophic bacteria. To date, our understanding of …

The Yunshan caldera complex is part of a larger scale, ca. 2000-km-long volcanic–plutonic
complex belt in the coastal region of SE China. The volcanic rocks in the caldera complex …

The progression from initial back-arc rifting to back-arc opening in ancient orogenic collages
is important for reconstructing subduction histories, constraining tectonic switching, and …
