The decrease in Al 2 O 3 and CaO below ∼5 wt % MgO reflects plagioclase becoming the dominant crystallizing mineral. FeO and TiO 2 decrease significantly below 3 wt % MgO, suggesting the onset of Tibearing magnetite crystallization (Fig. 5d and f). Variations in trace elements correspond to those of the major elements (Fig. 6; Table 1). The continuous decrease of Sc reflects fractional crystallization of .
