      abstract     = {Microbialites are organosedimentary structures that have
                      existed since the Precambrian and have endured through
                      geological time, serving as archives of Earth’s
                      environmental evolution. Today, they persist in only a few
                      environments markedly different from those in which they
                      first arose. Here, we report a modern microbialite reef in
                      Laguna Pozo Bravo (Puna region, Argentina), exposed to high
                      radiation, low oxygen pressure, and volcanic inputs
                      reminiscent of early Earth. Through physicochemical,
                      mineralogical, spectroscopic, electron microscopy, and
                      metagenomic analyses, we identified diverse microbial
                      communities with metabolic capacities that induce
                      mineralisation. Seasonal environmental fluctuations drive
                      cyclical changes in community composition, producing
                      potential mineralisation patterns. Our findings suggest that
                      carbon fixation and the metabolic drivers of alkalinity in
                      microbialites may have evolved over time. Moreover, the
                      variability in prokaryotic compositions among modern
                      microbialites demonstrates that carbonate precipitation is
                      governed by metabolic potential rather than taxonomy,
                      reinforcing their role as dynamic records of environmental
                      conditions.},
