Electrochemical characterization of mangrove sediments: A proposal of new proxies for organic matter oxidation
(Elsevier, 2019)
The voltammetric response of microparticulate deposits resulting from solvent evaporation of ethanolic extracts of mangrove sediments in contact with aqueous acetate buffer is hereby described. Dated sediment cores sampled ...
Evaluación de metales redox-sensitivos como proxies de paleoxigenación en un ambiente marino hipóxico del norte de Chile
(Sociedad de Biología de Chile, 2004)
Uso de proxies n-alcanos y Glycerol Dialkyl Glycerol Tetraethers (CDGTs) para la reconstrucción paleoambiental del lago Gatún, Panamá
(Universidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2018)
"El lago Gatún, es el cuerpo de agua más importante de Panamá, siendo su creación artificial durante la construcción del Canal de Panamá. Desde su creación 1907 el Lago Gatún ha sufrido cambios ecológicos y climáticos muy ...
Carbonate REE plus Y signatures from the restricted early marine phase of South Atlantic Ocean (late Aptian - Albian): The influence of early anoxic diagenesis on shale-normalized REE plus Y patterns of ancient carbonate rocks
(Elsevier B.V., 2018-07-01)
Rare earth elements plus yttrium have been extensively applied in paleoenvironmental studies of ancient carbonate successions due to their fractionation in the marine environment. However, in modem marine anoxic environments, ...
Palaeoredox conditions and sequence stratigraphy of the Cretaceous storm-dominated, mixed siliciclastic-carbonate ramp in the Eastern Cordillera Basin (Colombia): Evidence from sedimentary geochemical proxies and facies analysis
(2018)
The Cretaceous black shales of Colombia are among the most important successions in the north of South America and have attracted the attention of many geoscientists and exploration companies over the last few decades, ...
Palaeoredox conditions and sequence stratigraphy of the cretaceous storm-dominated, mixed siliciclastic-carbonate ramp in the Eastern Cordillera Basin (Colombia): evidence from sedimentary geochemical proxies and facies analysis
(Elsevier, 2018-10)
The Cretaceous black shales of Colombia are among the most important successions in the north of South America and have attracted the attention of many geoscientists and exploration companies over the last few decades, ...
Petrographic, mineralogical and geochemical characterization of fine-grained rocks of the Pilmatué Member (Upper Valanginian-lower hauterivian) of the Neuquén Basin (Argentina): Implications for siliciclastic input, carbonate productivity and redox conditions
(Pergamon-Elsevier Science Ltd, 2020-10)
Petrographic, mineralogical and geochemical analyses of mixed siliciclastic-carbonate offshore deposits of the Pilmatué Member (Neuquén Basin) were carried out to define two scenarios for deposition: a confined ramp setting ...
Centennial to millennial-scale changes in oxygenation and productivity in the Eastern Tropical South Pacific during the last 25,000 years
(Elsevier, 2015)
Oxygen minimum zones (OMZ) have expanded in all tropical oceans during the last 50 years resulting in habitat contraction and considerable changes in marine biogeochemistry. However, for a better understanding of the OMZ ...
Exposing the inside of the fine-grained siliciclastic tidal shelf deposits of the Alicia Formation, Tandilia Basin, during the Ediacaran anoxia in the Clymene Ocean
(Pergamon-Elsevier Science Ltd, 2020-11)
In this contribution we outline the outstanding attributes and inferred depositional controls for dark mudstones of the Alicia Formation (~570 Ma) in order to reveal the intrinsic characteristics of unknown Ediacaran marine ...
Redox stress reshapes carbon fluxes of Pseudomonas putida for cytosolic glucose oxidation and NADPH generation
(2020)
The soil bacterium and metabolic engineering platform Pseudomonas putida tolerates high levels of endogenous and exogenous oxidative stress, yet the ultimate reason of such property remains unknown. To shed light on this ...
