Evolving controls on mineralization in patagonian microbial mats and DNA sigantures
(Asociación Argentina de Sedimentología, 2021-12)
In recent years resulting investigations in living microbialites have provided significant data that have been critical to disentangle the role of the various biotic and abiotic processes contributing to their development. ...
Microbialite fields developed in a protected rocky coastline: The shallow carbonate ramp of the Aptian Romualdo Formation (Araripe Basin, NE Brazil)
(Elsevier B.V., 2019-07-01)
The Aptian Romualdo Formation is a siliciclastic-dominated sedimentary unit recording the last marine ingression within the Cretaceous interior basins of northeastern Brazil. At the western margin of the Araripe Basin, ...
The sediment microorganisms under the oxygen minimum zone: present day analogs of precambrian oceans?
(Universidad de Concepción.Facultad de Ciencias Naturales y Oceanográficas., 2006)
Growth morphologies and plausible stressors ruling the formation of Late Pleistocene lacustrine carbonate buildups in the Maquinchao Basin (Argentina)
(Wiley, 2019-07-22)
In a seminal paper regarding the mechanisms of carbonate stromatolite formation, Ginsburg (1991) emphasized the need to question to the relative role of microbes versus environment in their formation. The Maquinchao Basin ...
Geobiology of Andean microbial ecosystems discovered in Salar de Atacama, Chile
(Frontiers in Microbiology, 2021-10)
The Salar de Atacama in the Chilean Central Andes harbors unique microbial ecosystems due to extreme environmental conditions, such as high altitude, low oxygen pressure, high solar radiation, and high salinity. Combining ...
Microbialites of Balbuena IV Sequence (Danian), Salta Basin, Argentina: intrabioarchitectural characterization and definition of microcyclesMicrobialitos da Sequência Balbuena IV (Daniano), Bacia de Salta, Argentina: caracterização de intrabioarquiteturas e de microciclos

Stromatolites from the Aptian Crato Formation, a hypersaline lake system in the Araripe Basin, northeastern Brazil
(Springer, 2017-01-01)
The origin of the Cretaceous laminites of the Crato Formation, Araripe Basin, northeastern Brazil, has been intensely debated since the beginning of the last century. The monotonous, up to 10-m-thick succession composed ...
Microbialite-like structures in Cladophora sp. (Ulvophyceae) mats from a subtropical Andean basin: ecological implications
