• Resumen

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