Abstract
A cave formed in the course of sulfuric acid speleogenesis was explored in Uzbekistan. Evidence of the sulfuric acid speleogenesis includes the characteristic morphology of this cave, an upward flow of warm chloride–sulfate sodium–calcium groundwater with the release of hydrogen sulfide, a widespread development of the ascending passage, the presence of biomats in water, and characteristic secondary minerals. Based on the chemical composition and values of stable isotopes of oxygen and hydrogen, it is concluded that groundwater of the cave was formed by mixing of infiltration fresh and marine sedimentogenic waters. The cave is an example of active sulfuric acid speleogenesis in Uzbekistan.
