Monazite within a granite intruding the Kalak Nappe Complex (Norway) provides an informative example of a complex age spectrum in which U-Th-Pb data scatters for ~300 Ma along the Concordia curve. SIMS analyses yield 207Pb/235U ages (1s) of 876 ± 18 to 633 ± 15 Ma, and petrographically constrained a...
