Late Paleoproterozoic and Mesoproterozoic magmatism of the Nico Perez Terrane (Uruguay): Tightening up correlations in southwestern Gondwana
(Elsevier Science, 2019-04)
New geochronological, isotopic and geochemical data were obtained from the late Paleoproterozoic and Mesoproterozoic magmatic units of the Nico Perez Terrane (Uruguay). A U-Pb LA-ICP-MS zircon age of 1768 ± 11 Ma confirms ...
Underneath the pantanal wetland: A deep-time history of gondwana assembly, climate change, and the dawn of metazoan life
(2016-01-01)
Underneath the wetlands of the Brazilian Pantanal are hidden key ecological and geological events of the history of our planet. In this chapter we show that Precambrian rocks forming the hills and mountains surrounding the ...
