It is shown that different processes of the diffusive nature can participate in the rise of mineralization of the edge water, but baroosmose through fine-porous sediments (rocks) always plays the main role. The intraformational gradient of the osmotic pressure of water is a driving force of baroosmose resulting in the gradual formation of the vertical hydrogeochemical zonality at depths up to 1000–1500 m.
