• Resumen

  • The upper Albian La Mesa conglomerates and sandstones, from the northern side of Páramo de La Lora (Cantabria and Palencia), are attributed to a braided fluvial sedimentary system filling an incised valley. Facies of conglomerates and sandstones with horizontal and cross stratification and scanty lutites, all make up the concave-plane La Mesa unit. This is 24 km long, 20 m thick, and rests onto an angular unconformity with paleorelief. The vertical succesion is interpreted as relatively distal fluvial deposits (flood basin and crevase-splay) followed by a prograding major fluvial channel belt. In terms of sequence stratigraphy it is attributed to a fluvial TST systems tract.
