Finally, there is growing evidence that at least some large plutons never were large molten bodies of magma but grew incrementally. Stoping cannot be volumetrically important in incrementally emplaced plutons, because blocks can only fall through the volume that is molten at any given time.

(2004), have inferred that plutons grow by a prolonged sequence of magma injections and/or dikes. Such emplacement of magma by dikes, as opposed to emplacement of magma by stoping, is much less likely to produce xenoliths;

The absence of small xenoliths at pluton contacts thus argues against stoping. Fourth, at many plutons geochemical data clearly rule out significant assimilation of local wall rocks. Finally, there is growing evidence that many large plutons never were large molten bodies of magma, but grew incrementally.

These small apophyses may represent a snapshot of the magmas last attempt at stoping by “chipping” away at the margins of the magma chamber. The stoping process has created a complex contact geometry that is often parallel to the host rock anisotropy.

3. Viscous granitic magma also rises as diapirs (by displacement and stoping). 4. If wet, granitic magma often freezes at about 6 km depth because of the shape of its solidus curve, forming rounded plutons.The frequency of plutons suggests that many active volcanoes must have magma chambers within them.
