Biotic vs. abiotic signatures in Late Pleistocene lacustrine microbialites of the Maquinchao Basin (Argentina)
(International Association of Sedimentology, 2019)
Identifying and further weighting the role of biotic versus abiotic processes in microbialite formation remain a big challenge. The Maquinchao basin is a closed continental basin in northwestern Patagonia, east of the Andes ...
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 ...
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. ...
Evolving controls on mineralization in Patagonian microbial mats as inferred by water chemistry, microscopy and DNA signatures
(Asociación Argentina de Sedimentología (AAS), 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. ...
Organomineralization processes in freshwater stromatolites: a living example from eastern Patagonia
(interntional Association of Sedimentology Wiley on line Library, 2015-12)
Living stromatolites have been mostly described within shallow marine and (hyper)saline lacustrine environments. Southernmost South America lacks detailed investigations of these (organo)sedimentary buildups, particularly ...
Tracking organomineralization processes from living microbial mats to fossil microbialites
(Multidisciplinary Digital Publishing Institute, 2020-07-04)
Geneses of microbialites and, more precisely, lithification of microbial mats have been studiedin dierent settings to improve the recognition of biogenicity in the fossil record. Living microbial matsand fossil microbialites ...
