Constraints on the subduction erosion/extrusion cycle in the Paleozoic Acatlán Complex of southern Mexico: Geochemistry and geochronology of the type Piaxtla Suite

► 35 my subduction erosion/extrusion cycle in the Acatlán Complex of southern Mexico. ► 2.4 km/my extrusion rate similar to extrusion rates into upper plate in Variscan Iberia-Czech belt. ► Rift-passive margin and periarc protoliths for high-pressure rocks in Acatlán Complex.
