Resumen de Los conglomerados y areniscas de la Iglesia de Olleros, infrayacente de la serie de Utrillas en la vertiente norte del Páramo de La Lora (Albiense superior, Cantabria y Palencia)
S. Martínez de Rituerto Ibisate, Joaquín García Mondéjar
The upper Albian Iglesia de Olleros conglomerates and sandstones, from the northern side of Paramo de La Lora (Cantabria and Palencia), rest unconformably on the underlying series and are directly below the Utrillas Formation. Facies of conglomerates and sandstones with horizontal and cross stratification make up the concave-plane this unit. It is 14 km long, 10 m (maximum) thick, and rests onto a paleorelief that locally shows an angular unconformity. The Iglesia de Olleros unit is attributed to a braided fluvial sedimentary system filling an incised valley
