In many cases, quartz overgrowths were preferentially corroded and dissolved in the presence of pyrophyllite, most likely during acidic metasomatism .
Many experiments suggest that ancient subduction-related metasomatism affected OIB mantle sources long before island magmatism.
Textural relationships and geological context need to be determined to distinguish these burial-related phases from monazites ascribed to granite metasomatism or low-grade metamorphism.
Much more commonly, however, metasomatism involves chemical exchange with fluids; in the earth's crust these fluids are usually aqueous solutions.
In the cooler middle and upper crust, felsic magmatism and aqueous metasomatism are most important.
