Previous studies on monazite from An6e. a: ID-TIMS results obtained on An6e monazite grains, where one analysis point corresponds to one monazite grain, and showing complex discordance of monazite. Modified from Paquette et al. (2004). b: EMP dating results on An6e monazite grains showing a statistically well constrained date at 498 ± 4 Ma and a large dispersion between 2700 Ma and 700 Ma. Modified from Goncalves, (2002). c: Age map of monazite M6 in An6e with EMP in situ dates (white dots). Purple domains corresponds to the young domains while orange domains correspond to the oldest dates (white arrows). Modified from Goncalves et al. (2005). d: TEM-BF imaging on An6e monazite grain showing the presence of Pb rich inclusions. Modified from Seydoux-Guillaume et al. (2003).
