Ancud Volcanic Complex (Spanish: Complejo Volcánico de Ancud) is a volcanic complex of Oligocene and Miocene age located around Ancud with exposures in Chiloé Island, the Chilean mainland and smaller islets. Three subunits are recognized in the complex: Hueihuen, Teguaco and Cocotue.[1] The complex is part of the mid-Tertiary coastal magmatic belt in south-central Chile.[2]
