Ti-in-zircon temperatures obtained using the calibration of Watson et al. (2006) for a_TiO2 = 1 (gray lines) and a_TiO2 = 0.1 (black lines). Triangle markers indicate maximal temperatures calculated using the limit of detection (LOD) value obtained with the method of Pettke et al. (2012). Calibration uncertainty from Watson et al. (2006) is given at the 2σ level. The best Ti-in-zircon temperature estimate of each sample was taken as the median of all analyses above LOD, following Schiller and Finger (2019).
