(A) ²⁰⁸Pb/²³²Th versus ²⁰⁶Pb/²³⁸U diagram for monazites in sample AG17-A2. Dashed ellipses correspond to discordant data. Dark ellipses correspond to concordant ages affected (or not) by mixing between M1 and M2 monazite domains. White ellipses correspond to M2 analyses affected by common Pb contamination and mixing with M1 domain. Grey ellipses correspond to analyses used for the Discordia calculation. (B) Tera–Wasserburg diagram for the same sample. (C) ²⁰⁸Pb/²³²Th versus ²⁰⁶Pb/²³⁸U diagram for monazite in sample AG17-A3. (D) Tera–Wasserburg diagram for the same sample. (E) ²⁰⁸Pb/²³²Th versus ²⁰⁶Pb/²³⁸U diagram for monazite in sample AG17-H1. (F) Concordia diagram for the same sample.
