Isotopic results obtained with SIMS on monazite grains. The dataset has been color coded following textural position. Uncertainties are given at 2σ. The whole dataset is discordant. Three discordia have been calculated with Isoplot software selecting the all dataset (dotted line), the data obtained in monazite located in garnet and quartz (green and blue data), the data obtained in monazite located in coronitic texture (red data) except one that follows a different trend.
