Sulfuric acid, hypogene karst in the Guadalupe mountains of New Mexico and West Texas, USA, 2000, Hill C. A.
Carlsbad Cavern, Lechuguilla Cave, and other caves in the Guadalupe Mountains are probably the worlds best examples of karst formed by sulfuric acid in a hypogene setting. Four episodes of karstification have occurred in these mountains from Late Permian time to the present, the sulfuric acid episode being the last of these four. Sulfuric acid karst can be recognized by its large passage size, ramiform-spongework pattern, horizontal passages connected by deep pits and fissures, location beneath structural and stratigraphic traps, gypsum and native sulfur deposits, and the sulfuric-acid/H2S indicator minerals endellite, alunite, natroalunite, and tyuyamunite. Guadalupe caves formed in a diffuse-flow aquifer regime where caves may have acted as mixing chambers for hypogene-derived H2S and meteoric-derived fresh water. How cave hydrology has been related to regional hydrology during the late-Tertiary to present is poorly understood. Sulfuric acid karst is an integral part of H2S-degassing hydrocarbon basins which also can contain economic sulfur and Mississippi Valley-type ore deposits.

Sulfidic ground-water chemistry in the Frasassi Caves, Italy, 2008, Galdenzi S. , Cocchioni M. , Moricheui L. , Amici V. , And Scud S.
A year-long study of the sulfidic aquifer in the Frasassi caves (central Ita ly) employed chemical analysis of the water and measurements of its level, as well as assessments of the concentration of H2S, CO2, and O2 in the cave air. Bica rbonate water seepage derives from diffuse infiltration of meteoric water into the karst surface, and contributes to sulfidic ground-water dilution, with a percentage that varies between 30% and 60% during the year. Even less diluted sulfidic ground water was found in a localized area of the cave between Lago Verde and nearby springs . This water rises from a deeper phreatic zone , and its chemistry changes only slightly with the seasons with a contribution of seepage water that does not exceed 20'10 . In order to understand how the H2S oxidation, which is considered the main cave forming process, is influenced by the seasonal changes in the cave hydrology, the sulfide/total sulfur ratio was related to ground-water dilution and air composition. The data suggest that in the upper phreatic zone, limestone corrosion due to H2S oxidation is prominent in the wet season because of the high recharge of Oj-rich seepage water, while in the dry season, the H2S content increases, but the extent of oxidation is lower. In the cave atmosphere, the low H2S content in ground water during the wet season inhibits the release of this gas, but the H2S concentration increases in the dry season, favoring its oxidation in the air and the replacement of limestone with gypsum on the cave walls.

Monitoring climatological, hydrological and geochemical parameters in the Pre Nol cave (Belgium): implication for the interpretation of speleothem isotopic and geochemical time-series, 2008, Verheyden S. , Genty D. , Deflandre G. , Quinif Y. And Keppens E.
Pre Nol cave climatology (air and water temperature, PCO2), hydrology (drip rate, conductivity) and geochemistry of water and calcite deposits (?18O, ?13C, Mg/Ca and Sr/Ca) where studied to better interpret stable isotopic and trace element variations of speleothems. Results of an automated monitoring station and of manual sampling between 1991 and 1998 have demonstrated the highly seasonal signal of drip rate, its control by water excess and rainfall, and, at a shorter scale to air pressure changes. The modern calcite deposit study suggests a relationship between cave calcite isotopic composition (?18O and ?13C) and drip rate likely due to variations in degree of isotopic equilibrium during calcite precipitation. ?18O and ?13C of the calcite are therefore, through drip rate, linked to water recharge. Mg/Ca and Sr/Ca ratios of Pre Nol cave calcite, depend closely on the residence time of the water, and therefore are also linked to drip rate and therefore to water recharge. This crossed link of ?18O and ?13C as of Mg/Ca and Sr/Ca to water recharge may explain the very similar variations of these four parameters along the longitudinal axis of a Holocene stalagmite, but it may also be the consequence of kinetic effects during calcite precipitation as suggested by similar variations of the four parameters along a single layer of the Holocene stalagmite.
