Can water in the mantle enter the crust and turn the crustal components into hydrated minerals?

23 October 2023 1 4K Report

As title.

Yes, water in the mantle can migrate towards the crust due to the elevated temperature at depth. This water induces mineralogical transformations through metasomatism during its journey. This phenomenon is common in subduction zones where tectonic plates converge, with one plate sinking beneath the other. As the subducting plate descends into the mantle, it releases water due to the high pressure and temperature. This water can then trigger chemical reactions with minerals in the surrounding rocks of the mantle and/or crust, transforming them into hydrated minerals.

Is it possible to prepare clay minerals by mixing pure oxides of required elements? What would be theoretical difficulties with it?

Practically this is not at all necessary. But theoretically, would hydrous/hydrothermal synthesis be enough (like mix 1 mole alumina gel and 4 mole silica gel and gently heat) or would it require...
