Description
When water freezes slowly, the solutes present in the water will not be incorporated in the crystal lattice of the ice. This slow and continuous freezing process will accompany the onset and evolution of permafrost conditions at the surface and in the bedrock in advance of ice cover during future glaciation events. During this process, salts that have been present in the surface waters and groundwaters will tend to accumulate at the propagating freeze-out front.
