Recording of climate and diagenesis through sedimentary DNA and fossil pigments at Laguna Potrok Aike, Argentina
(Copernicus Publications, 2016-04)
Aquatic sediments record past climatic conditions while providing a wide range of ecological niches for microorganisms. In theory, benthic microbial community composition should depend on environmental features and geochemical ...
Lacustrine sediments provide geochemical evidence of environmental change during the last millennium in southeastern Brazil
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009)
A 172 cm-long sediment core was collected from a small pristine lake situated within a centripetal drainage basin in a tropical karst environment (Ribeira River valley, southeastern Brazil) in order to investigate the ...

Diatoms as indicators of hydrological and climatic changes in Laguna Potrok Aike (Patagonia) since the Late Pleistocene
(Elsevier Science, 2015-01)
Southern South America is a key site to study climate variability in the Southern Hemisphere, allowing for a wide variety of climatic archives. Recently, several investigations using lacustrine sediments have provided an ...
Late Pleistocene-Holocene earthquake-inducedslumps and soft-sediment deformation structures in the Acequion River valley, Central Precordillera, Argentina
(De Gruyter, 2014-07)
Evidence of earthquake-induced liquefaction features in the Acequión river valley, central western Argentina, is analysed. Well-preserved soft-sediment deformation structures are present in Late Pleistocene deposits; they ...
