of experimental studies have been conducted on the development of metasomatic zones using analogues of the crust–mantle interface (Oyanagi et al.2015,2018,2020). These studies have suggested that the relative mobility of Si and Mg via diffusion in aqueous fluids plays an important role in the ...
Fluids mediate the transport of subducted slab material and play a crucial role in the generation of arc magmas. However, the source of subduction-derived fluids remains debated. The Kamchatka arc is an ideal subduction zone to identify the source of fluids because the arc magmas are comparably ...
The role of magmatic processes as a significant mechanism for the generation of voluminous silicic crust and the development of Cordilleran plateaus remains a lingering question in part because of the inherent difficulty in quantifying plutonic volumes.
Moreover, rocks from the middle zone have bulk-rock Th/Yb and Nb/Yb ratios similar to ratios of island arc basalts. Therefore, the Wangjiangshan intrusion could be formed in island arc environment. We argue that the tearing and breakoff of subduction oceanic slab resulted in asthenosphere ...
our experimental design of the 1:1 volume mixture of albite and water translates to the water contents of ca. 5 wt.% H2O, which is assumed to be the water content in the cold subduction zone9,30,31. Furthermore, the formation of the hydrated Na-smectite from albite is confirmed by ...
magmatism of the Basque Cantabrian Basin is of alkaline characteristics and spans from the Valanginian to Santonian (Lamolda et al.1983; García-Garmilla and Carracedo-Sánchez1989; Montigny et al.1986; García-Mondejar et al.2018). The magmatic locus was located along the rift axis in this ...
