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 ...
The lithosphere of Southern Peru: A result of the accretion of allochthonous blocks during the Mesoproterozoic
(IRD ÉditionsFRA, 2008)
Southern Peru exhibits different juxtaposed structural blocks. These blocks have a distinct sedimentary, tectonic and magmatic evolution. They are bounded by complex, mainly NW-SE fault systems, locally marked by Cenozoic ...

(ELSEVIER SCIENCE BV, 2011)
The Capivarita Anorthosite, formed in an intraplate environment and later metamorphosed under amphibolites fades conditions, is exposed in the Dom Feliciano Belt as part of the Brasiliano magmatic arc and occurs as a ...
A-type magmatism in the sierras of Maz and Espinal: A new record of Rodinia break-up in the Western Sierras Pampeanas of Argentina
(Elsevier Science, 2009-08)
Two orthogneisses have been recognized in the sierras of Espinal and Maz (Western Sierras Pampeanas, NW Argentina) that were emplaced within a Grenvillian metasedimentary sequence. Microcline, plagioclase and quartz are ...
