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

Mechanism of plagioclase albitization
Journal of Sedimentary Research, 1992 Abstract Observations of closely spaced porous and cemented sandstones from the San Joaquin basin, the Los Angeles basin and the Gulf Coast reveal that albitization of plagioclase occurs during fracturing of the detrital plagioclase grains.

Transformation of Ordered Albite into Kaolinite: Implication for the Booklet Morphology
, 2022 Kaolinization of feldspars is widespread in various geological environments including weathering and hydrothermal environments. However, the mechanisms of such mineral transformation and kaolinite formation remain obscure.

Experimental determination of plagioclase dissolution rates as a function of its composition and pH at 22°C. [PDF]
, 2014 The steady-state, far-from-equilibrium dissolution rates of nine distinct plagioclases ranging in composition from An2 to An89 were measured in mixed flow reactors at 22 ± 2 C and pH from 2 to 11.
