Traditionally, it was thought that caves formed only through the dissolution of rock by groundwater; however, the unusual chemistry of sulfuric acid caves suggested that microorganisms could also play an important role in cave formation. By studying this biogeochemistry, researchers discovered that caves could form through microbial oxidation of hydrogen sulfide gas, which accounted for as much as 25% of cave formation worldwide. They have hypothesized a new potential mechanism for microbially-driven cave formation, based on microbial respiration of iron(III) minerals in iron-rich rocks (known as banded iron formations; BIF). The identification of cave forming processes in BIF is significant as it dramatically expands the environments in wh...
