• Resumen

  • Late Quaternary paleochannel and fluvial deposits characterization in the Bay of Cadiz have been carried out by geophysical, cores, and archeological data. They are located over alluvial deposits of regressive and lowstands systems tracts, and below the coastal deposits of transgressive systems tracts belong to the last depositional sequence. Paleochannels were generated during the sea level fall and lowstand position in the last glaciation stage, but fluvial sedimentary infill was produced after, as the sea level rose, during the transgression. Paleochannel and fluvial deposits have been also affected by several tectonic episodes which influence its position, internal structure and lateral movement, during and after its sedimentation
