• Resumen

  • Here we explore the dominating mechanisms controlling sedimentation on the Galician (NW Spain) continental margin during the late Quaternary. Over the past 30 ka, detrital input, marine productivity and sea level changes alternatively influenced sediment availability on the slope, with deep-water currents appearing as the main controlling parameter. Furthermore, our data demonstrate how small-scale morphological features and sediment contribution from the neighboring shelf related to local export pathways play an additional role incontrolling slope sedimentation.
