Geochemical Evidence for Slab Melting in the Trans-Mexican Volcanic Belt
, 2006 Geochemical studies of Plio-Quaternary volcanic rocks from the Valle de Bravo-Zitacuaro volcanic field (VBZ) in central Mexico indicate that slab melting plays a key role in the petrogenesis of the Trans-Mexican Volcanic Belt.

Flux melting of subducting carbonated sediments: An experimental study
Geosystems and Geoenvironment, 2023 Subduction zones play a critical role in the global carbon cycle by regulating carbon exchange between the Earth's surface and interior. Processes that are known to release carbon from the slab, including metamorphic decarbonation and carbonate ...

Production of High‐Sr Andesite and Dacite Magmas by Melting of Subducting Oceanic Lithosphere at Propagating Slab Tears [PDF]
, 2018 We present K-Ar ages, major and trace element concentrations, and Sr-Nd-Pb isotope data for late Cenozoic volcanic rocks from the Chugoku district, southwest Japan arc.

Molybdenum isotopes unmask slab dehydration and melting beneath the Mariana arc
Nature Communications, 2021 How serpentinites in the forearc mantle and subducted lithosphere become involved in enriching the subarc mantle source of arc magmas is controversial.

Earth and Space Science, 2021 Cenozoic volcanic rocks in the East Asian continental margin usually form because of asthenosphere upwelling and resultant decompression melting, and their origins are important in deciphering mantle geodynamics attributed to intraplate volcanism.

Geosciences, 2022 Adakites are Y- and Yb-depleted, SiO2- and Sr-enriched rocks with elevated Sr/Y and La/Yb ratios originally thought to represent partial melts of subducted metabasalt, based on their association with the subduction of young ( 20 ppm) arc basalts in ...

Are Adakites Slab Melts or High-pressure Fractionated Mantle Melts? [PDF]
Journal of Petrology, 2016 Adakites are unusual felsic igneous rocks commonly associated with asthenospheric slab window opening or fast subduction of a young (

Greenland Ice Sheet Ice Slab Expansion and Thickening
Geophysical Research Letters, 2023 We use airborne accumulation radar data acquired over the Greenland Ice Sheet between 2002 and 2018 to identify changes in ice slab extent and thickness. We show that ice slabs several meters thick were already present at least as early as 2002.
