ABSTRACT

There are 3 units to be considered: lower, middle and upper.

The lower section is characterized by a stack of thin lava interspersed with pyroclastic levels crossed by a strong network of dikes. The middle section, known as Tabular or “Plateau de San Andrés” consists of nearly horizontal lava flows. The upper section is characterized by the emission of pyroclastic rocks with subordinate lavas, known as Group Ventejis Picos-Moles Volcanoes.
