Notes

Abstract:
Recognition and understanding of the important role of sulfur redox processes in developing karst has grown over the last 25 years with the discovery of remarkable sulfur-rich caves worldwide and advances in geomicrobiology. Recent work has shown that microbes interact with hydrocarbons, calcium sulfate bedrock, magmatic fluids, and sulfide ore minerals to reduce gypsum/anhydrite to calcite, produce hydrogen sulfide and sulfuric acid, convert limestone to gypsum, increase porosity in carbonate bedrocks, precipitate massive sulfur, and deposit Mississippi Valley-Type (MVT) ores. These processes are most active in the shallow phreatic and vadose-phreatic subsurface, where transitions between aerobic and anaerobic conditions exist.
