The bottom of this sequence is formed by coral limestone deposit interpreted as fringing reef with a most likely age corresponding to the onset and progress of Last Interglacial (132-120 kyrago). This deposit is covered and eroded by rampant dunes and alluvial fans that recorded a rapid sea-level drop. A very similar sequence of facies have been described by several authors in the Bahamas and other Caribbean areas, showing rapid and abrupt sea-level fluctuations that occurred within the beginning of Marine Isotope Stage 5.

Lo más relevante de dicha evolución es la presencia de un paleorrelieve correspondiente a fondos de paleovalles conservados en los puntos más bajos de la divisoria entre ambos ríos, y también en hombreras de la cuenca del Besaya. En ocasiones aparece cubierto por materiales de origen mixto (fluvial y gravitacional) de edad presumible Mio- Plioceno. La incisión de la red del Besaya progresó en dichos paleovalles, desmantelando su cobertera mio-pliocena y resedimentándola en parte como megaflujos (“debris flows”) multiepisódicos de gran espesor y abanicos, que a su vez están siendo incididos por el encajamiento actual. La neotectónica del área queda reflejada por la acti...
