- Special type of metamorphism by which solutions of
magmatic origin move through
solid rocks, change ions
with them, and convert them into rocks that achieve granitic character without having
passed through magmatic stage.

- An essentially metamorphic process by which a solid rock is converted into
a granitic rock by the entry and exit of material, without passing through
a magmatic stage. Some authors include in this term all granitic rocks
formed from sediments by any process, regardless of the amount of melting
or evidence of movement. The precise mechanism, frequency, and magnitude
of the processes are still in dispute. Syn: granitification CF: transfusion
