Una rampa carbonatada con fases de emersión y excavación de paleocañones (Calcarenitas de Peñalba, Albiense inferior, Bizkaia)
The architecture and vertical evolution of facies in the Peñalba Calcarenitic ramp (Bizkaia) suggest several phases of emersion. These were coeval with the formation of incised canyons which were later filled with mass-gravity deposits and autochthonous marls. Proximal ramp facies display paleokarst...

| Resumo: | The architecture and vertical evolution of facies in the Peñalba Calcarenitic ramp (Bizkaia) suggest several phases of emersion. These were coeval with the formation of incised canyons which were later filled with mass-gravity deposits and autochthonous marls. Proximal ramp facies display paleokarst features, whereas distal ramp sediments are more terrigenous and show most of the incised erosions. |
