Botryogen is of interest to geologists that study volcanic fumerole regions and the surface of Mars. There is evidence indicates that sulfate minerals may exist in the permafrost on Mars. Sulfates are important secondary minerals produced from the evaporation of fluids. The formations of these minerals testify to earlier, wetter and an acidic climate on Mars.

Sulfates can form as evaporates in standing bodies of water, by precipitation from saturated groundwater, or by acidic fog alteration.

Significant sulfate deposits on Mars occur in two main regions: within and near the equatorial Valles Marineris canyon system and in dunes around the north polar ice cap. Sulfates are found throughout Valles Marineris, in related outflow channels such as Aram Chaos, and in areas east of Valles Marineris such as Meridiani Planum.
