Determination of natural radionuclides in lichen samples of Canoparmelia texana
(Sao Paulo: ABEN, 2009, 2014)
Analytical procedures for determining Pb and Sr isotopic compositions in water samples by ID-TIMS
(Sociedade Brasileira de Química, 2008)
Few articles deal with lead and strontium isotopic analysis of water samples. The aim of this study was to define the chemical procedures for Pb and Sr isotopic analyses of groundwater samples from an urban sedimentary ...
Slab decarbonation and CO2 recycling in the Southwestern Colombian volcanic arc
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-02-01)
The contribution of subducted carbonate sediments to the genesis of the Southwestern Colombian arc magmas was investigated using a comprehensive petrography and geochemical analysis, including determination of major and ...
Using delta C-13 stable isotopes to quantify individual-level diet variation
(SpringerNew YorkEUA, 2007)
Food web structure in a double-basin ultra-oligotrophic lake in Northwest Patagonia, Argentina, using carbon and nitrogen stable isotopes
(Elsevier, 2013-01)
Fish, benthic macroinvertebrates, macrophytes, biofilm, plankton, and terrestrial material were analyzed for stable nitrogen (15N) and carbon isotopes (13C) to study the food web structure of a double-basined, ultra-oligotrophic ...
Nd and Pb isotope signatures on the Southeastern South American upper margin: Implications for sediment transport and source rocks
(ELSEVIER SCIENCE BV, 2008)
Neodymium and lead isotope values in sediment samples were used to interpret sediment transport and source rocks on the Southeastern South American upper margin. The sediments of the Argentinian margin exhibit an average ...
The effect of hydrothermal alteration on the Sr and Nd isotopic signatures of the Barra do Itapirapua Carbonatite, Southern Brazil
(Univ Chicago Press, 1999-03-01)
The Cretaceous Barra do Itapirapua carbonatite in southern Brazil experienced extensive postmagmatic hydrothermal alteration. In this article, Sr and Nd isotope ratios of coexisting samples of hydrothermally overprinted ...
