Abstract

Many hypogene caves are formed by sulfuric acid produced by the oxidation of sulfides, particularly hydrogen sulfide. This cave development can take place below, at, or above the water table. Most cave enlargement is subaerial, in water films and droplets that absorb gaseous hydrogen sulfide and oxygen. Sulfuric acid caves have irregular patterns with large variations in cross section and elevation, with relatively few subhorizontal passages formed along the water table. Cave origin is scattered, localized, and sporadic. Sulfuric acid caves provide evidence for regional geomorphic and tectonic history, groundwater flow patterns, and redox geochemistry.
