The flat-topped Cerro el Chino lava dome, seen here from the SSE, is a silicic lava dome of the Acatlán volcanic field. This volcanic field, located SW of La Primavera caldera, consists of a group of andesitic cones, rhyolitic lava domes, and lava flows associated with an indistinct caldera. Following eruption of the compositionally zoned Acatlán ignimbrite, a series of rhyolitic and dacitic lava domes, andesitic cones and lava flows, and Quaternary cinder cones were erupted throughout the Acatlán volcanic field.
