Ice caves on Mars: Hoarfrost and microclimates

Abstract Caves on planet Mars could potentially contain water ice deposits. Here, the physical processes responsible for growth and preservation of spelean formations are assessed. Martian caves situated in environments where phase transitions only by sublimation. The predominant type cave is expected to be perennial hoarfrost that slowly grows supersaturated cavities. role microclimates maintaining bodies evaluated comparatively. Free forced convection transport less sensible heat than denser terrestrial atmosphere. Cooling through sublimation also far weaker caves. Hence, cooling deposits flow cave, often a crucial factor caves, insignificant Mars, which limits geographic extent can expected.
