Several processes are involved in the formation of nodules, including the precipitation of metals from seawater ( hydrogenous ), the remobilization of manganese in the water column ( diagenetic ), the derivation of metals from hot springs associated with volcanic activity ( hydrothermal ), the decomposition of basaltic debris by seawater ( halmyrolitic ) and the precipitation of metal hydroxides through the activity of microorganisms ( biogenic ).

Several of these processes may operate concurrently or they may follow one another during the formation of a nodule.
