The role of climate in the accumulation of lithium-rich brine in the Central Andes
(Elsevier, 2013-09)
Lithium-rich brine within the sub-surface of the Salar del Hombre Muerto (SHM) salt pan in the Andes of northwestern Argentina has a chemical and isotopic composition which is consistent with Li derived from several sources: ...
Carbonate laminae recorded in a siliciclastic tidal flat colonized by microbial mats
(Elsevier Science, 2020-07-15)
Microbial mats in siliciclastic coastal environments are considered as non-lithifying systems that lack the potential for calcification. This work documents precipitation and preservation of well-defined, laterally continuous ...
Importance of accessory minerals for the control of water chemistry of the Pampean aquifer, province of Buenos Aires, Argentina
(Elsevier Science, 2018-01)
The Pampean aquifer, in south east Argentina, is mainly constituted of loess-like sediments. These are clastic sediments mainly composed of quartz and aluminosilicates and calcrete concretions. Its hydrochemistry is generally ...
The BIOSUN project: an astrobiological approach to study the origin of life
(International Astronomical UnionFlorianópolis, 2013)
During the early ages of the Earth the magnetic activity
of the young Sun was much stronger than that
of the present Sun, in particular for radiation emitted
below 1700 ˚A. Such enhanced radiation fluxes
could play a ...
Iron and Calcium Biomineralizations in the Pampean Coastal Plains, Argentina: Their Role in the Environmental Reconstruction of the Holocene
(Springer, 2018)
Biomineralizations are biogenic composites, crystalline or amorphous,produced by the metabolic activity of organisms distributed all over the world. Theaim of this work was to evaluate the presence of iron and calcium ...
Geology of Península Valdés
(Springer, 2017)
The surface of Península Valdés is gently cut, characterized by plateaus, sea cliffs, and spits as well as depressions caused by a complex process of tectonic, deflation, fluvial erosion, and mass wasting. Subsurface geology ...
Distinctive archaeal composition of an artisanal crystallizer pond and functional insights into salt-saturated hypersaline environment adaptation.
Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad ...
