BackgroundPleistocene lava flows cover a broad area between Huauchinango in the Sierra Madre Oriental and the city of Poza Rica along the Gulf of Mexico coastal plain. The basaltic and hawaiite lava flows fill valleys to depths of several hundred meters and are almost continuous from Huauchinango to Poza Rica. Possibly correlative lava flows are located in the Metlaltoyuca area to the NW of Poza Rica. K-Ar ages for these lava flows range from 1-64 to 1.31 million years (Ferrari et al., 2005).
