a Weighted mean 207Pb/206Pb for common Pb component within apatite (blue filled bars denotes outliers). b Stacked histograms and probability density plot for different minerals using apparent 207Pb-corrected ages (colours as per part c), with best estimate of dyke crystallization age shown by vertical dotted line. c Inverse concordia plot for titanite, zircon, and apatite. Grey triangle denotes field of mixtures between ancient zircon inclusion component and the common–radiogenic titanite mixing array. Error bars are all at the two sigma level.
