Comment:

Results of TIMS analysis of rutile and description of grain fractions. 206Pb/204Pb ratios are corrected for spike and fractionation only. Radiogenic ratios are corrected for spike, fractionation and initial Pb using the K-feldspar composition. Data were reduced and errors propagated using AnySpike (Schmitz and Schoene, 2007).
