Imbrication of sedimentary wedges derived from volcanic arcs to the north and south produced a 10-100-km-wide, stratigraphically north-facing pile. Thermal relaxation in the 20 m.y. following accretion of the southern arc resulted in melting of the accretionary pile to produce peraluminous granite and associated low-pressure metamorphism.
