3. . Late-stage fractional crystallization – forms separate fluid phase Fractional crystallization enriches late melt in H 2 O, other volatiles, incompatible elements Saturation point reached Hydrous vapor phase formed Produces boiling off of H 2 O as magma cools (retrograde boiling) Results in silicate-saturated saturated vapor vapor-saturated late silicate liquid enriched in volatiles and incompatible elements
Volatile release increases P - fractures roof rocks of magma chamber Vapor and melt escape along fractures as dikes Silicate melt composed of quartz and feldspar forms small dikes of aplite Vapor phase forms pegmatites (coarser- grained dikes)
