    Diverse intrusion modes during the construction of a high-silica magma reservoir: Evidence from La Obra-Cerro Blanco intrusive suite (central Chile)

    Several conceptual models have been proposed for the amalgamation of granitoid plutons, which range from incremental growth to single-stage emplacement of these systems. This diversity of views has led to intense debate about the thermomechanical state of silicic intrusions and the magma differentiation paths within the crust. In this contribution, we present a comprehensive petrologic, geochronologic, and magnetic fabric data set from the La Obra-Cerro Blanco intrusive suite, which allows us to explore the petrogenesis and magma emplacement processes in the upper crust.
