• Resumen

  • At the septentrional margin of the Ebro Basin, the conglomeratic facies of Uncastillo Formation correspond to two complex cyclic Tectosedimentary Units (TSU Ul and U). Towards the West, thesê TSU lie on Campodarbe Formation whose upper section is recognizable as another cyclic TSU (C), and towards the Fast lie on marine paleogene and mesozoic sediments of the Pyrenean Externa/ Sierras. The fining-up megasequences of the TSU C2, Ul and IJ2 represent the initial burial of the thrust units of the south Pyrenean frontal thrust complex, placed successively from West to East during the time of the coarsening-up megasequences of former TSU
