Naolinco Volcanic Field

Volcanic field · Mexico · 2000m

The Naolinco Volcanic Field consists of a broad area of scattered Quaternary cones and associated lava flows north of the city of Jalapa, the capital city of the state of Veracruz. Cerro Acatlán in the distance is the largest cone, and is located NE of the town of Naolinco de Victoria. This and other nearby cones have fed lava flows that traveled to the S and SE. The barren area in the foreground is part of the Río Naolinco lava flow, which erupted from vents on the NE flank of Cofre de Perote volcano.

Geological summary

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.
