The molybdenum (Mo) isotope system is a powerful tool for tracing recycled crustal
components in volcanic rocks. Existing Mo isotope data show that intraplate basalts have …

The recycling of mafic oceanic crust in subduction zones represents an important geological
process to explain the geochemical diversity of the Earth's mantle. Based on radiogenic …

Mafic arc igneous rocks with oceanic crust-derived fluids in their mantle sources generally
show heavy Mo isotope compositions. However, these rocks may exhibit variable Mo …

Subduction redistributes elements between Earth's principal geochemical reservoirs,
modifying the chemical composition of Earth's mantle, crust, atmosphere, and hydrosphere …

Highly variable molybdenum (Mo) isotope compositions have been reported for mafic arc
volcanics above oceanic subduction zones. The heavy Mo isotope signatures of mafic arc …

Mass‐dependent Mo isotope variations are a promising new tracer to study magmatic
processes in different geological settings. We report the first Mo isotope data for the …

The petrogenesis of basaltic arc lavas with heavy Mo isotopic compositions is controversial.
Given that oceanic crust preferentially loses isotopically heavy Mo during subduction at …

Key Points Forearc serpentinites show high Mo/Ce ratios and δ98/95Mo values Lizardite‐
serpentinites are influenced by shallow slab‐derived fluid, while blue‐serpentinites are …

The contribution of recycled oceanic crust to the mantle source of mid-ocean ridge basalts
(MORBs) remains a subject of debate, as radiogenic isotopes alone yield ambiguous …

Subduction zones are pivotal in understanding the interaction between Earth's surface and
deep materials. The markedly diverse Mo isotopic compositions observed in arc magmas …
