Definition
Freeze drying (cryodessication) combines the virtues of dehydration and chilling for preserving. Freeze drying works by freezing the material and then reducing the surrounding pressure and adding enough heat to sublime the ice.
The mars analogue carbonate deposits in subglacial volcanic complex on Svalbard (Norway) is believed to have been formed through a process of cryodessication and/or thermal evaporation.
