Stromatolites found in Hapcheon crater

A team of researchers from the Institute of Geosciences and Earth Resources in South Korea>>> discovered stromatolites within the Hapcheon impact crater>>>. These layered rock structures, formed by ancient microbial communities, suggest that hydrothermal lakes created by asteroid impacts may have provided ideal environments for early oxygen-producing life. This discovery offers new insights into the Great Oxidation Event, a period when Earth's atmosphere became rich in oxygen, and has implications for the search for past microbial life on Mars>>>. Dr. Jaesoo Lim>>> led the study, which was published in Communications Earth & Environment.
