DEF

Endroit du fond marin où une mince couche de sédiments s'est durcie pour former une surface encroûtée d'oxyde de fer et de manganèse.

OBS

Il est très fréquent de trouver, dans ces surfaces rubéfiées, des concentrations anormales de minéraux authigènes (exemples : glauconite, sidérite, dolomie, etc.).

OBS

On observe les hard grounds dans les sédiments marins, notamment au sommet de séries calcaires, et on pense qu'ils traduisent un arrêt de la sédimentation causé par l'activité de courants de fond.
