The assembly of large silicic magmatic centers encompasses processes that span many time and length scales from the initial processes of mantle melting and extraction, to the transport, interaction, differentiation, and residence in the crust. These magmatic systems are coupled to their crustal containers, exchanging mass and energy, and responding to evolving tectonic conditions and crustal lithologies. In this work, we use multiscale numerical models in conjunction with recent information from the on-going geophysical and geochemical investigation of one large silicic center, Laguna del Maule (Chile), to examine the response of the crust to sustained input of magmas from the mantle. The Laguna del Maule (LdM) volcanic field in Chile has been one of the most active rhyolitic centers following deglaciation, and this part of the arc has likely been active for 25 MY (Hildreth et al, 2010). Laguna del Maule has …
