Rhythmic modal layering most easily explained by crystal settling interrupted by periodic large-scale convective overturn of the entire cooling unit Reinjection of more primitive magma may explain major compositional shifts and cases of irregular cryptic variations
Density currents Cooler, heavy-element element-enriched, enriched, and/or crystal-laden laden liquid descends and moves across the floor of a magma chamber Dense crystals held in suspension by agitation Light crystals like plagioclase also trapped and carried downward
