Re-Os isotope and highly siderophile element systematics of the Parana continental flood basalts (Brazil)
(Elsevier B.V., 2012-07-01)
Basalts of the Parana continental flood basalt (PCFB) province erupted through dominantly Proterozoic continental crust during the Cretaceous. In order to examine the mantle source(s) of this major flood basalt province, ...
Slab-derived components in the subcontinental lithospheric mantle beneath Chilean Patagonia: Geochemistry and Sr–Nd–Pb isotopes of mantle xenoliths and host basalt
(Elsevier, 2017)
In subduction zones, ultramafic xenoliths hosted in alkaline basalts can yield significant information about
the role of potential slab-derived components in the subcontinental lithospheric mantle (SCLM). Chemical ...
Crustal controls on light noble gas isotope variability along the Andean Volcanic Arc
(European Assoc Geochemistry, 2021)
This study combines new noble gas data from fluid inclusions in minerals from
Sabancaya, Ubinas, and El Misti (CVZ, Peru) and Villarica (South Chile, SVZ) with
a revised noble gas compilation in the Andes, to identify ...
Different lead sources in an abandoned uranium mine (Urgeirica - Central Portugal) and its environment impact - isotopic evidence
(GEOLOGICAL SOC PUBL HOUSEBATH, 2012)
Different lead sources were identified in a large uranium tailings deposit (5Mton) in the Central Region of Portugal using lead isotopic ratios obtained by ICP-QMS. These ratios helped to clarify the different sources of ...
Isotopic constraints on the source of Argentinian loess - With implications for atmospheric circulation and the provenance of Antarctic dust during recent glacial maxima
(Elsevier Science, 2003-07)
We present rare-earth element (REE) and Sr-Nd isotopic data for Argentinian loess (28-38°S) with two aims: (1) to examine the source regions of Argentinian loess and the constraints that these put on palaeo-wind directions; ...
Isotopic evidence for the late Brasiliano (500-550 Ma) ore-forming mineralization of the Araes gold deposit, Brazil
(BELLWETHER PUBL LTD, 2008)
The Araes gold deposit, located in eastern Mato Grosso State, central Brazil, is hosted in Neoproterozoic volcanosedimentary rocks of the Paraguay belt, which formed during collision of the Amazonian craton and the Rio Apa ...

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 ...
