Contourites are sediments deposited or substantially reworked by bottom currents. The study of contourites is nowadays crucial for several fields of fundamental and applied research: palaeoclimatology and paleoceanography, since these fairly continuous and relatively high-resolution sediments hold the key for priceless information on the variability in circulation patter, current velocity, oceanographic history and basin interconnectivity; hydrocarbon exploration, since accumulation of source rocks may be favoured by weak bottom currents, whereas "clean" deep-sea sands may be formed by robust flows; slope stability, since low-permeability fine-grained contourites facilitate the formation of overpressurized gliding planes when fresh contourites with a high pore-water content becomes rapidly loaded, or when their rigid biosiliceous microfabric collapses due to diagenetic conditions.
