Earth's rotation variability triggers explosive eruptions in subduction zones [PDF]
, 2015 The uneven Earth’s spinning has been reported to affect geological processes, i.e. tectonism, seismicity and volcanism, on a planetary scale. Here, we show that changes of the length of day (LOD) influence eruptive activity at subduction margins ...

On the fluid-mobility of molybdenum, tungsten, and antimony in subduction systems [PDF]
, 2011 Molybdenum (Mo) and tungsten (W) have long been regarded as being more or less immobile during slab fluid-induced arc magma generation. Here we characterize about 180 samples of young, predominantly mafic to intermediate tephras and lavas for their Mo,

The role of elasticity in slab bending [PDF]
, 2014 International audiencePrevious studies showed that plate rheology exerts a dominant control on the shape and velocity of subducting plates. Here, we perform a systematic investigation of the role of elasticity in slab bending, using fully dynamic 2-D ...

Frontiers in Earth Science, 2021 Platinum-group elements (PGE) and gold are a promising tool to assess the processes of mantle melting beneath the subduction zones. However, fractionation processes in magmas inevitably overwrite the initial metal budgets of magmas, making constraints on

Contrasting magma chemistry in the Candelaria IOCG district caused by changing tectonic regimes
Scientific ReportsIron oxide-copper-gold (IOCG) deposits are a vital source of copper and critical elements for emerging clean technologies. Andean-type IOCG deposits form in continental arcs undergoing extension, and they have a temporal relationship with magmatism ...

Subduction by Submesoscales [PDF]
Journal of Geophysical Research: Oceans, 2018 AbstractSeveral studies have demonstrated the relevance of submesoscales (SM) to the production of phytoplankton and the ocean absorption of anthropogenic CO2. One variable that thus far has not been fully quantified is the SM‐induced rates of subduction and obduction at the bottom of the mixed layer.

Dynamic evolution of changbaishan volcanism in Northeast China illuminated by machine learning
Frontiers in Earth Science, 2023 Previous studies propose that there is a mantle upwelling that generated the Cenozoic basalts in Changbaishan. However, the dominant source and mechanism of the mantle upwelling remains highly debated.

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]
, 2004 Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

Deep fault sliding rates for Ka-Ping block of Xinjiang based on repeating earthquakes
Open GeosciencesThe seismically active Ka-Ping Block within Xinjiang, China, represents a zone of potential earthquake hazards, and existing surface measurements cannot fully reflect the area’s sub-surface slip rates.
