A role for subducted albite in the water cycle and alkalinity of subduction fluids

open access: yesNature Communications, 2021
Albite is one of the major constituents in the Earth’s crust. Here, the authors report that under hydrous cold subduction conditions, albite undergoes breakdown into hydrated smectite and other phases, which release alkaline fluids into the mantle wedge.

Megathrust Shear Modulated by Albite Metasomatism in Subduction Mélanges

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Aseismic megathrust slip downdip of the seismogenic zone is accommodated by either steady creep or episodic slow slip events (SSEs). However, the geological conditions defining the rheology of megathrust slip remain elusive.
