The Naolinco volcanic field in the Sierra de Chiconquiaco range north of Jalapa (Xalapa), the capital city of the state of Veracruz, consists of a broad area of scattered Quaternary pyroclastic cones and associated dominantly basaltic lava flows. Late-Pleistocene to Holocene pyroclastic cones cover an E-W-trending area on both sides of the town of Naolinco de Victoria. The largest cone is 2000-m-high Cerro Acatlán, located NE of Naolinco de Victoria. This and other nearby cones have fed voluminous lava flows that traveled down regional gradients to the south and SE. The Coacoatzintla lava flow from the Rincón de Chapultepec scoria cone in the western part of the field was erupted about 3000 years ago and is the youngest flow of the Naolinco volcanic field.
