An introductory review of the thermal structure of subduction zones: III—Comparison between models and observations
PE van Keken, CR Wilson - Progress in Earth and Planetary Science, 2023 - Springer
The thermal structure of subduction zones is fundamental to our understanding of the
physical and chemical processes that occur at active convergent plate margins. These …

Continental growth seen through the sedimentary record
Sedimentary rocks and detrital minerals sample large areas of the continental crust, and
they are increasingly seen as a reliable archive for its global evolution. This study presents …

Serpentinite fluids and slab-melting in the Aleutian arc: Evidence from molybdenum isotopes and boron systematics
Mo isotope compositions have been increasingly used as a source tracer in magmatic
systems. Here, we investigate the relative role of subducting oceanic crust, fluid-rich sources …

Molybdenum systematics of subducted crust record reactive fluid flow from underlying slab serpentine dehydration
Fluids liberated from subducting slabs are critical in global geochemical cycles. We
investigate the behaviour of Mo during slab dehydration using two suites of exhumed …
