Processes that may have been significant during crystallization of plagioclase-phyric magma in the Hosenbein pluton include (in approximate order of increasing magma viscosity) (1) convective flow, (2) crystal settling and/or flotation, (3) development of cumulate crystal frameworks, (4) porous flow of intercumulus melt, (5) compaction, and (6) synplutonic deformation.
The crystal settling speeds were based primarily on the data published by Hogan (1994).
