Which term refers to sediment formed by minerals precipitated directly from seawater?

Explanation:
Hydrogenous sediments are formed when minerals precipitate directly from seawater. This is a chemical, in-place process where dissolved ions crystallize into solid minerals on the seafloor without involvement of organisms or land-derived material. Classic examples include manganese nodules and phosphorites. Evaporites are related, since they precipitate salts as seawater concentrates and evaporates, but the general term for minerals precipitating from seawater itself is hydrogenous sediment.
