DOIAbstract
Carbonate precipitation in hypersaline lakes is controlled by a combination of physicochemical and microbiological processes. These processes are recorded, at least partially, in the textural and chemical signatures preserved in the resulting carbonates. Unraveling of these controls is important to have a better understanding of environmental signatures (for example, climate, local hydrology, and sedimentology) and biogeochemical signatures (for example, carbon cycling, microbe–mineral interactions) preserved there, and helps to improve our understanding of environmental evolution preserved in recent and ancient sedimentary carbonates. This chapter reviews data on the carbonate system in Laguna Negra, a hypersaline lake in the Puna–Altiplan...
