Deskripsi

The transition from smectite to illite requires potassium incorporation, yet the role of microbes in facilitating K+ uptake remains debated, especially during the early Earth. Here, the authors suggest that the Paleoproterozoic microbial mats extracted potassium from sea water and induced localized illitization during early low-temperature diagenesis.
