Researchers at University of Akron investigate high microbial communities in BIF caves, theorizing microbes use iron to respire and cause rust-like oxides to become soluble. This process could be responsible for voids forming within the cave walls, eventually leading to new cave formation.
Researchers found microbes actively contribute to dripstone formation, with layers mirroring seasonal changes. The discovery sheds light on the role of biological life in shaping Earth's geology and has implications for understanding microbial life beyond Earth.
