a Chemical affinity changes for plagioclase formation as a function of oxide content increase in liquid. The pink and pale blue shaded regions denote the ranges of affinity variations due to ±300 MPa pressure and ±10 °C temperature changes, respectively. b Chemical affinity changes as a function of An component. c, d The same for clinopyroxene. The pink and pale blue shaded regions represent the ranges of affinity variations due to ±20 °C of temperature and ±200 MPa of pressure changes, respectively. The experiment selected is FM15748.
