Whole rock major and trace element composition plotted versus time for (a) MgO, (b) CaO/Al2O3 and (c) Cr. A log scale is used for Cr to emphasize the trend reversal in May 2015. Dashed lines indicate: (1) the compositional trend reversal (between 19 and 23 May 2015, which is ascribed to the delivery of new, less differentiated magma), and (2) the arrival of cumulative olivine during the August-October 2015 eruption
