Naolinco Volcanic Field

The Naolinco Volcanic Field in the Sierra de Chiconquiaco range north of Jalapa (Xalapa), Veracruz, consists of a broad area of scattered Quaternary pyroclastic cones and associated dominantly basaltic lava flows. These cones cover an E-W-trending area on both sides of the town of Naolinco de Victoria; the largest is Cerro Acatlán, located NE of the town. This and other nearby cones produced voluminous lava flows that traveled S and SE. The Coacoatzintla lava flow from the Rincón de Chapultepec scoria cone was erupted about 1200 BCE. A cluster of basaltic cinder cones S of the town of Las Vigas de Ramirez produced lava flows have traveled eastward to beyond the city of Xalapa (Jalapa). A flow from the El Volcancillo vent was radiocarbon dated at about 1150 CE.
