Fig. 8

Representative cathodoluminescence images of zircon grains from the Cézarenque gneisses. The locations of laser spots (white circles) are indicated along with the spot name (#XX). The corresponding ²⁰⁶Pb/²³⁸U dates (if < 1.2 Ga) or ²⁰⁷Pb/²⁰⁶Pb dates (if > 1.2 Ga) are quoted with 2σ uncertainty, in Ma. All displayed analyses are concordant.
