BSE images of monazite (samples AG17-A2, AG17-J15b and AG17-J6b). Monazites are found as inclusions within large garnets (A) or found in the matrix (B, C and D) in contact with biotites (D), K-feldspars (B) or garnets (C). Large monazite grains are surrounded by small grains or recrystallized branches (C) or can be clearly deformed (B). Small monazite grains can also form clusters aligned along the foliation plane (D). La (left) and Y (right) X-ray maps of monazites (E) in matrix and (F) at the edge of garnet in sample AG17-J15a. Circles show the location of the LA-ICPMS pits (9 μm) and their corresponding ²⁰⁸Pb/²³²Th ages. Circles show the location of the LA-ICPMS pits (9 μm) and their corresponding ²⁰⁸Pb/²³²Th ages (In red: concordant Cretaceous age; in blue: mixing age; in black: Variscan age).
