Monazite and xenotime geochronological results for the VP7r orthogneiss. All data are uncorrected for common Pb. (a) Tera-Wasserburg diagram showing the U/Pb results for monazite I. The white ellipse has not been considered in the free regression calculated with the grey ellipses. (b) Tera-Wasserburg diagram showing the U/Pb results for xenotime. The white ellipses have not been considered in the free regression calculated with the grey ellipses. Only one analysis was consistent in both the ²⁰⁸Pb/²³²Th–²⁰⁶Pb/²³⁸U and ²⁰⁶Pb/²³⁸U–²⁰⁷Pb/²³⁵U systems, so the probability histogram is not available for xenotime in this sample.
