A New Workflow to Assess Emplacement Duration and Melt Residence Time of Compositionally Diverse Magmas Emplaced in a Sub-volcanic Reservoir

Construction durations of magma reservoirs are commonly inferred from U-Pb zircon geochronology using various statistical methods to interpret zircon U-Pb age spectra (e.g.weighted mean ages of concordant zircon populations).However, in compositionally different magmas, zircon saturation and crystallization are predicted to occur at different times relative to other mineral phases and the geological event of interest; for instance, magma emplacement.The timescales of these
