Fig. 10. Conventional concordia diagrams showing U-Pb (LA-ICP-MS) ages of magmatic zircon from Mérida Massif metagranites: (a) metatonalite from Don Álvaro Metaigneous Complex (DAMC), combined with the frequency and probability density distribution plot. (b) Concordia age plot obtained from the youngest zircon population in the metatonalite from Don Álvaro Metaigneous Complex, which is interpreted as the protolith age. (c) felsic gneiss from San Andrés Metaigneous Complex (SAMIC), combined with the frequency and probability density distribution plot. (d) Concordia age plot obtained from the youngest zircon population in the felsic gneiss from San Andrés Metaigneous Complex, which is interpreted as the protolith age. (e) granodiorite from Valle Real Metaigneous Complex (VRMIC), combined with the frequency and probability density distribution plot. (f) Concordia age plot obtained from the youngest zircon population in the granodiorite from Valle Real Metaigneous Complex, which is interpreted as the protolith age. E. Rojo-Pérez, U. Linnemann, M.
