Current theory suggests that the first step in crystal growth is the formation of nuclei of a critical size in a supersaturated solution.
Although the discrepancy is small, it is particularly significant that in the experiments the melt became supersaturated, a possibility not allowed for in the theory.
The generation of nuclei comes from supersaturated water which is injected into the tunnel through small orifices.
Diurnal temperature fluctuations likely cause the soil atmosphere to fluctuate in relative humidity between supersaturated while cooling, and less than 100% when warming.
Our models predict that the melt becomes supersaturated, which causes further solidification away from the cooled boundary.
Thereby the whole of the liquid region can become supersaturated.
The modification makes a fundamental difference, however, when the melt is convecting, since supersaturated fluid can be advected from the interface into the whole body of the melt.
Gypsum becomes supersaturated, precipitates from the water column, and accumulates on the lake bottom, where it is preserved in sediments.
