Authigenic clays as precursors to carbonate precipitation in saline lakes of Salar de Llamara, Northern Chile

In this study, we examined associations between microbial communities, Mg-clay minerals, and carbonates in microbial mat samples from the Puquios of the Salar de Llamara using scanning electron microscopy, energy dispersive X-ray spectroscopy, focused ion beam nanotomography, and transmission electron microscopy. Data shared here correspond to Figs. 4-6, and include the raw data used to create the Supplemental Videos 1 and 2.
