(a) to (e) Maps to show spatial variations in trace element geochemistry and isotope data. a) U concentration.(b) Th concentration. c) Th/U ratio. d) Pb concentration. e) 207Pb/206Pb age. Base image is panchromatic cathodoluminescence image shown in Fig. 3a. (f) Concordia plot of all U-Pb SHRIMP analyses for whole grain (n = 50). Error boxes are 1σ. All data are ≥ 94% concordant. The combined mean 207Pb/206Pb age is 2,451 ± 14 Ma, with an MSWD of 1.3.
