Lost Terranes of Zealandia: possible development of late Paleozoic and early Mesozoic sedimentary basins at the southwest Pacific margin of Gondwanaland, and their destination as terranes in southern South America
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2010)
Bimodal character of the Late Paleozoic glaciations in Argentina and bipolarity of climatic changes
(Elsevier Science, 2010-12)
The Upper Paleozoic sedimentary rock sequences of Argentina show an outstanding record of climatic fluctuations during this interval and the complexity and rapidity of the climatic changes. There were two distinct events ...

Deciphering the late paleozoic–cenozoic tectonic history of the inner central andes forearc: an update from the salar de Punta Negra basin of Northern Chile
(Frontiers Media, 2022)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic-Cenozoic tectonic evolution of the ...
Deciphering the Late Paleozoic–Cenozoic Tectonic History of the Inner Central Andes Forearc: An Update From the Salar de Punta Negra Basin of Northern Chile
(Frontiers Media S.A., 2022-01)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic–Cenozoic tectonic evolution of the ...
Tunnel-valley fills in the Paraná Basin and their implications for the extent of late Paleozoic glaciation in SW Gondwana
(2021-03-01)
Tunnel valleys are subglacial incisions formed mainly by meltwater erosion on soft sediment overridden by glaciers. Despite being common in the Pleistocene and Ordovician glacial record, where their fills constitute excellent ...
Late Paleozoic tectono-sedimentary evolution of eastern Chaco-Paraná Basin (Uruguay, Brazil, Argentina and Paraguay)
(2021-03-01)
Recent surface and subsurface information from the Chaco-Paraná Basin in Argentina, Brazil, Paraguay and Uruguay south of the Asunción Rio Grande Arch allowed proposing a regional tectonic-sedimentary evolution for the ...
Exhumed subglacial landscape in Uruguay: Erosional landforms, depositional environments, and paleo-ice flow in the context of the late Paleozoic Gondwanan glaciation
(2018-07-01)
A well-exposed glacial surface sculpted on Precambrian crystalline basement rocks occurs below the glacial succession of the San Gregorio Formation on the eastern border of the Chaco-Parana Basin in Uruguay and was formed ...
Detrital zircons from late Paleozoic accretionary complexes in north-central Chile (28°-32°S): Possible fingerprints of the Chilenia terrane
(Pergamon-Elsevier Science Ltd, 2011-05)
During the Paleozoic the Andean basement of central Chile and Argentina grew westwards by the amalgamation of diverse tectonostratigraphic terranes some of them derived from Laurentia. The last to be accreted, in the ...
