Subduction zones not only return oceanic lithosphere into the mantle, but are also sites
where chemical components are transferred from the downgoing plate back to the surface in …

Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

Crustal recycling at convergent plate boundaries is essential to mantle heterogeneity.
However, crustal signatures in the mantle source of basaltic rocks above subduction zones …

This textbook is a complete rewrite, and expansion of Hugh Rollinson's highly successful
1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

We extracted all volcanic arc rock analyses calculated to be in equilibrium with mantle
olivine from the global georoc database. This results in 938 primitive melt compositions from …

Subducted crust refertilizes the subarc mantle wedge as well as the deep convecting mantle.
In the subarc region, mass transfer occurs mainly through fluids, melts, or supercritical …
