Minerals that crystallize directly from seawater are examples of hydrogenous sediment.

halite deposits
They are just called minerals.
actually no sediment does not form from minerals and crystallize from water.
minerals that crystallize directly from ocean waters
Non-Clastic, or chemical, sedimentary rock is formed from dissolved minerals. These rocks are made of chemical sediments that have been dissolved from minerals. Solid minerals precipitate out of the solution in water. These minerals layer, and the water above them causes the pressure which forms the rock.
A hydrothermal solution is a very hot mixture of water and dissolved substances. Hydrothermal solutions have temperatures between 1000C and 3000C. When these solutions come into contact with existing materials, chemical reactions occur to form new materials. Also, when such solutions cool, some of the elements in them combine to form such minerals as quarts and pyrite.
In general, minerals can form in two ways: through the crystallization of melted materials, and through the crystallization of materials dissolved in water.
