14C chronology and stable isotopes on Lymnaea viatrix shells in northwest Patagonia, Argentina. Do they express the Antarctic climatic reversal?
(Springer, 2018-07)
A multi-isotope environmental record comprising an upper section of the late Pleistocene and the lower and middle Holocene, including isotopic data on 30 samples of peat, marl, tufa, Lymnaea viatrix shells, and Hippidion ...
Zooarchaeological and Stable Isotopic Assessments on Pinniped-Human Relations in the Beagle Channel (Tierra del Fuego, Southern South America)
(John Wiley & Sons Inc, 2013-11)
Recent zooarchaeological investigations in the Beagle Channel region have shown long-term variations characterised by a high inter-taxonomic dominance of pinnipeds during the first moments of the archaeological sequence ...
Lama guanicoe bone collagen stable isotope (C and N) indicate climatic and ecological variation during Holocene in Northwest Patagonia
(Pergamon-Elsevier Science Ltd, 2020-05)
This paper explores how significant are the ecological and climatic variables to influence the stable isotopes of guanacos. Lama guanicoe bone collagen carbon and nitrogen stable isotope ratios are assumed as a macro ...
Carbon isotopic signature and organic matter composition of cenomanian high-latitude paleosols of Southern Patagonia
(Multidisciplinary Digital Publishing Institute, 2021-09)
The Cenomanian Mata Amarilla Formation (MAF) in southern Patagonia (⁓55° S paleolatitude, Austral-Magallanes Basin, Argentina) is composed mainly of stacked fluvial deposits with intercalated paleosols, which document ...
Stable oxygen and carbon isotope composition of holocene mytilidae from the camarones coast (Chubut, argentina): Palaeoceanographic implications
(MDPI AG, 2020-12)
The stable isotope composition of living and of Holocene Mytilidae shells was measured in the area of Camarones (Chubut, Argentina). The most striking results were the high δ18 O values measured in samples older than ca. ...
Stable isotope composition of a vertebrate assemblage from the Tacuarembó Formation, Uruguay (Late Jurassic-Early Cretaceous): Geochemical insight into an arid continental environment
(Asociación Paleontológica Argentina, 2019)
The Late Jurassic–Early Cretaceous Tacuarembó Formation (Uruguay) consists of aeolian dunes, ephemeral and perennial river deposits that are part of the vast Botucatu Desert, Parana Basin. It preserved a diverse vertebrate ...
Insights into the distribution of shallow-marine to estuarine Early Miocene oysters from southwestern Patagonia: sedimentologic and stable isotope constraints
(Society For Sedimentary Geology, 2013-06)
The early Miocene Patagoniense transgression in southwestern Patagonia, Argentina (Estancia 25 de Mayo Formation), consists of shallow marine to estuarine deposits that bear numerous oyster shell beds distributed all over ...
Linking stable isotopes and biochemical responses in Balanus glandula under sewage influence
(Pergamon-Elsevier Science Ltd, 2018-02)
In the present study, we analyzed the influence of untreated sewage exposure on carbon (δ13C) and nitrogen (δ15N) isotopic composition and several biochemical responses in the barnacle Balanus glandula. The main objective ...
Chemostratigraphy and diagenetic constraints on Neoproterozoic carbonate successions from the Sierras Bayas Group, Tandilia System, Argentina
(Elsevier Science, 2007-02)
Carbon and oxygen isotopic data, combined with a detailed diagenetic study, obtained from undeformed and unmetamorphosed dolomite and limestone from the Neoproterozoic Sierras Bayas Group, Argentina, provide a new record ...
