Abstract
    The northern sector of the Argentine Continental Margin includes areas with significant differences in the morphosedimentary configuration of the contouritic drifts. In the northernmost part (MP area) they are represented by relatively continuous deposits not deeply affected by gravity downslope processes, whereas in the southernmost part (BB area) they are discontinuous and highly dissected by mass-transport and turbiditic deposits. These differences can be addressed to local conditioning factors manifested in a different morphology of submarine canyons, tectonic influence and sediment dynamics, which have relevant implicances in slope stability and geohazard.
