[HTML][HTML] Atlas of the underworld: Slab remnants in the mantle, their sinking history, and a new outlook on lower mantle viscosity

DG Van der Meer, DJJ Van Hinsbergen, W Spakman - Tectonophysics, 2018 - Elsevier
Across the entire mantle we interpret 94 positive seismic wave-speed anomalies as

Variable water input controls evolution of the Lesser Antilles volcanic arc

GF Cooper, CG Macpherson, JD Blundy, B Maunder… - Nature, 2020 - nature.com
Oceanic lithosphere carries volatiles, notably water, into the mantle through subduction at
convergent plate boundaries. This subducted water exercises control on the production of …

Boron isotopes in the continental crust: granites, pegmatites, felsic volcanic rocks, and related ore deposits

RB Trumbull, JF Slack - Boron isotopes: the fifth element, 2018 - Springer
Boron is an incompatible lithophile element that is readily transported by granitic melts and
hydrous fluids and therefore is concentrated in the continental crust relative to the mantle …
