Bacterial mats, formed by successively accumulating biofilms, are the main constructive component of the oxide ferromanganese ores on the oceanic floor. The coordinated behavior of the bacterial colonies in the biofilms controlled the growth of the stromatolites and onkolites structures. Biofilms of the stromatolite bacterial mats represent the microbial community, with the thread bacteria forming a poiygonal network that determines a piliar structure of the crusts. Bacterial mats in nodules are festoon-shaped. Biofilms in festoons intensely interact with the environment, assimilating petrogenic components and consuming the sedimentary material.
