DEF

The stage in the cooling of a magma during which the residual fluid is strongly enriched in water and other volatiles.

OBS

The exact limits of the stage are variously defined by different authors, in terms of phase assemblage, temperature, composition and/or vapor pressure; most definitions consider it as the last stage of igneous activity, coming at a later time, and hence at a lower temperature, than the pegmatitic stage.
