WebThis process in which wall rocks are incorporated into the magma is called assimilation. Because assimilation is accompanied by crystallization, it is likely that both fractional crystallization and assimilation will take place simultaneously. WebIn addition, crystal zoning patterns always occurred in orthopyroxene (e.g., Cr zoning and Ti zoning ), which have been recognized as archives of magmatic processes such as fractional crystallization [10,11], magma replenishment [12,13], magma convection , and subsolidus equilibration [15,16].
