Inside the volcano: Three-dimensional magmatic architecture of a buried shield volcano

Recent data suggest that magma chambers beneath volcanoes are formed incrementally through amalgamation of smaller intrusions. Here we present the first high-resolution threedimensional reconstruction of an ancient volcanic plumbing system as a large laccolithic complex. The complex appears to have fed both surface volcanism and an extensive sill network beneath the volcanic edifice. Our results reveal for the first time the entire multicomponent plumbing system within a large ancient shield volcano.
