... to SE. It is worth noting that the overlying Mértola Formation turbidites of the Baixo Alentejo Flysch Group provided the same faunal association and Late Visean spores. This suggests a gradual lithological transition between the Brancanes and the Mértola Formation. The cut to the north of the road...
