Monazite geochronological results for the VP7-2 (a-d) and VP7c (e, f) paragneisses. All data are uncorrected for common Pb. (a) Tera-Wasserburg diagram showing the U/Pb results for monazite I. White ellipses correspond to discordant analyses. White dashed ellipses are concordant but were not included in the weighted mean dates calculated from the grey ellipses. (b) Probability histogram of ²⁰⁸Pb/²³²Th dates for monazite I (only concordant data in both the U/Pb systems and the ²⁰⁶Pb/²³⁸U −²⁰⁸Pb/²³²Th systems). (c) Tera-Wasserburg diagram showing the U/Pb results for monazite II. Only the dark grey ellipses were taken into account in the free regression calculation. In the inset (concordia date), the light grey ellipse with the bold outline corresponds to the calculated concordia date. (d) Probability histogram of ²⁰⁸Pb/²³²Th dates for monazite II (only concordant data in both the U/Pb systems and the ²⁰⁶Pb/²³⁸U −²⁰⁸Pb/²³²Th systems). (e) Tera-Wasserburg diagram showing the U/Pb results in monazite I. White ellipses have not been considered in the free regression calculated with the grey ellipses. (f) Probability histogram of ²⁰⁸Pb/²³²Th dates for monazite I. Only consistent dates in both the ²⁰⁸Pb/²³²Th–²⁰⁶Pb/²³⁸U and ²⁰⁶Pb/²³⁸U–²⁰⁷Pb/²³⁵U systems are shown in (b), (d) and (f).
