Abstract This thesis investigates the emplacement and magmatic evolution of the Val Fredda Complex (VFC), located in the southern tip of the Adamello batholith, N. Italy. The VFC provides insights into the history of a pluton that was constructed by multiple injections of compositionally diverse magmas, where we can observe complex relationships among mafic sheets injected into solidifying felsic magmas. We present an isotopic and geochemical data set which utilizes high precision ID-TIMS geochronology, trace element analyses from zircon and titanite combined with Hf isotopic compositions of zircon, all from the same mineral volume. This data set is integrated with in situ trace element analyses, field observations and data published in the literature.
