Figure 5
(a) Sequence of renderings (vertical cut) from the freezing experiment. It is possible to appreciate the growth of ice from the bottom of the sample (freezing front) and the residual brine trapped at the ice crystal boundaries. The brine facing the freezing front also increases in salinity (increase in X-ray attenuation → higher gray value) while the freezing proceeds. (b) Reconstructed slice of the sample at −14°C, close to the bottom of the sample. It is possible to appreciate the complexity of the pattern of residual brine generated by the crystallization of the ice needles and platelets. A film of residual brine surrounding the lower part of the sand grains is also visible.
