Ciclo de transgresión-regresión en los depósitos costeros de la Unidad de Olleros de Paredes Rubias (Albiense superior, Páramo de La Lora, Palencia)

Abstract

The Olleros de Paredes Rubias succesion was attributed to a transitional marine-continental environment.

A detailed study of the lower part of that succesion has shown several subenvironments of the shore-zone (lagoon, backshore, upper shoreface and lower shoreface). The repetitive arrangement of the fades corresponding to these subenvironments defines a cycle of rising and falling relative sea level, with the falling stage producing a forced regression. This cycle can be compared with the transgression part of models proposed for incised valley fills
