U-ages in soils and groundwater evidencing wet periods 400-600 kyr ago in southeast Brazil
(Elsevier B.V., 2007-07-01)
U-238 and its radiogenic daughter U-234 have been utilized for dating soil formation and groundwater residence time during the last 1.5 million years, in this case based on the U-clissolution/precipitation occurring during ...

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 ...
Stable isotopes identify age- and sex-specific dietary partitioning and foraging habitat segregation in southern giant petrels breeding in Antarctica and southern Patagonia
(Springer, 2012-03)
We examined the isotopic signatures (δ 13C, δ 15N) of adult body feathers from southern giant petrels Macronectes giganteus collected at two breeding colonies in Antarctica (Potter Peninsula and Cape Geddes) and one in ...
Characterization of the stable isotopic composition of precipitation, surface, and subsurface waters in a small Andean catchment in northern Ecuador
(Universidad de Cuenca, 2021-12-16)
Combining traditional hydrometric data with environmental tracers such as water stable isotopes has proven valuable to improve the understanding of catchment hydrology. Nevertheless, the application of isotopic tracers in ...
Isotopic trends in the diets of hunter-gatherers of the lower Paraná wetland, South America
(Elsevier Ltd, 2016-10)
The results of the isotopic analysis of 23 individuals recovered in the lower Paraná wetland, South America, are presented. The samples were recovered from complex hunter-gatherer sites ranging from the years 1800 to 600 BP. ...
Provenance of northwestern Patagonian river sediments (44-48 degrees S): A critical evaluation of mineralogical, geochemical and isotopic tracers
(Elsevier, 2020)
The ability to trace and quantify sediment provenance in northwestern Patagonia is increasingly needed to properly understand modem sediment erosion and transport processes in this rapidly changing environment, and to ...
