• Resumen

  • Detailed mapping and facies analysis of onshore Lower Albian sequences in the Trucfos-Somorrostro area led to the establishment of a major paleogeographic trough for the Lower Albian. Listric faulting on the western edge of the trough created a half graben morphology filled with both mass-gravity and traction submarine deposits. Led-zinc ore deposits were emplaced on the karstified calcarenite following the trough fault system
