microbialites

Microbialites are layered rock formations created by ancient and some modern communities of microorganisms, mainly bacteria and algae. These microorganisms trap andbind minerals from water, especially calcium carbonate, as they grow and reproduce. Over time, these layers build up into complex structures, resembling coral reefs or rocks. They are important because they help scientists understand early life on Earth, as well as the history of Earth's climate and environment. Microbialites can be found in environments like lakes, lagoons, and marine settings, both today and in the fossil record, showcasing the long-lasting impact of microbial life.
