Pb, Nd, Sr, AND Os ISOTOPIC SYSTEMATICS OF BRAZILIAN CRETACEOUS POTASSIC ROCKSPb, Nd, Sr, AND Os ISOTOPIC SYSTEMATICS OF BRAZILIAN CRETACEOUS POTASSIC ROCKS
(Sociedade Brasileira de Geologia, 2017)
Sr-Nd-Pb isotopic constraints on the nature of the mantle sources involved in the genesis of the high-Ti tholeiites from northern Paraná Continental Flood Basalts (Brazil)
(2013-10-01)
There has been little research on geochemistry and isotopic compositions in tholeiites of the Northern region from the Paraná Continental Flood Basalts (PCFB), one of the largest continental provinces of the world. In order ...

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, ...

Re-Os isotopes in Andean IOCGs and IOA deposits: Implications for the source of metals
(2015)
The Re-Os isotopic system has been extensively used to
determine the age and source of metals in a variety of mineral
deposits.
Published Re-Os data for Chilean IOCG and IOA
deposits indicated a radiogenic signature (initial ...
Re-Os isotope constraints on subcontinental lithospheric mantle evolution of southern South America
(Elsevier Science, 2008-04)
We present Re-Os isotopic data for widely dispersed mantle xenoliths carried to the surface of southern South America (36°-52° S) by Eocene to recent alkaline magmatism. Our hypothesis is that the lithospheric mantle ...
Re–Os isotopic constraints on the source of platinum-group minerals (PGMs) from the Vestřev pyrope-rich garnet placer deposit, Bohemian Massif
(Elsevier, 2015)
Mineralogical studies of the heavy fraction from a Holocene pyrope-rich garnet placer deposit at Vestřev
(Krkonoše Piedmont Basin, Bohemian Massif) have identified the presence of very rare grains of platinum
group ...
