BackgroundAn area of Quaternary phonolitic and basaltic pyroclastic cones and lava flows is located along the Gulf of Mexico SE of the Sierra de Tamaulipas. Trachytic and phonolitic eruptions were followed by the emission of young basaltic lava flows from cinder cones. Scattered areas of Tertiary or Quaternary volcanic rocks also lie along a NNW-SSE-trending line on the coastal plain east and NE of the Sierra de Tamaulipas and in areas farther west toward the base of the mountain range.
