Gravity settling Differential motion of crystals and liquid under the influence of gravity due to their differences in density Cumulate texture: mutually touching phenocrysts embedded in an interstitial matrix which is the crystallized residual melt
Gravity settling – Ternary Phase Diagram 3 Phases = An (anorthite( anorthite), Di (diopside( diopside), and Fo (forsterite olivine) Point a → olivine layer at base of pluton if olivine sinks first Next get ol + cpx layer Last get ol + cpx + plag layer Figure 7-2.
