Abstract

The process of mineral formation may be observed in modern shallow lakes, where carbonates, sulfates, chlorides y silicates precipitate in association with microbial mats. Classical models explained the precipitation of most of the pha- ses with pure physicochemical mechanisms without considering biological influence. Recent studies considered biological influence focusing to isolate microorganisms. Here, we propose an experimental design to incubate the whole microbial mats running in parallel with controls designed for pure abiotic precipitation. Thus, the observations made in the experiments, including the development of the mats y the minerals precipitated, can be used as a tool for understanding microbial-mineral interactions by comparison with field observations. Remarkably, the minerals precipitated in the laboratory resemble the natural precipitates in textures y paragenesis.
