Depositional settings and evolution of a fjord system during the carboniferous glaciation in Northwest Argentina
(Elsevier Science, 2018-07)
Fjord systems, represented by glacial diamictites and postglacial transgressive shales, formed in the basins of western Argentina during the late Carboniferous Gondwana glaciation. Well exposed fjord deposits of the Guandacol ...
A paleoclimatic reconstruction of the Carboniferous-Permian paleovalley fill in the eastern Paganzo Basin: Insights into glacial extent and deglaciation of southwestern Gondwana
(Pergamon-Elsevier Science Ltd, 2019-11)
During the mid-Carboniferous, ice centers located in present-day western Argentina disappeared until the late Cenozoic with glaciation of the Andes. The disappearance of mid-Carboniferous glaciers and the subsequent climate ...
Sedimentology of the mid-Carboniferous fill of the Olta paleovalley, eastern Paganzo Basin, Argentina: Implications for glaciation and controls on diachronous deglaciation in western Gondwana during the late Paleozoic Ice Age
(Pergamon-Elsevier Science Ltd, 2018-07)
Both global and regional climate drivers contributed to glaciation during the late Paleozoic Ice Age (LPIA). However, the transition from icehouse to greenhouse conditions was asynchronous across Gondwana suggesting that, ...
Stratigraphy and palynology of a late Paleozoic glacial paleovalley in the Andean Precordillera, Argentina
(Elsevier Science, 2014-10)
A new locality where Carboniferous glacial diamictite appears confined to paleovalleys is described in the north of the Argentinian Precordillera. The glacial deposits of the lower part of the Carboniferous Quebrada Larga ...
TOPOGRAPHIC REGISTERS OF PALEO-VALLEYS ON THE SOUTHEASTERN BRAZILIAN CONTINENTAL SHELF
(INST OCEANOGRAFICO, UNIV SAO PAULO, 2009)
The evolution of paleo-incised-valleys in the Sao Paulo State region of the southeastern Brazilian continental shelf is presented in this study in relation to the post Last Glacial Maximum (LGM) sea-level rises based on ...
Gondwana Glacial Paleolandscape, Diamictite Record of Carboniferous Valley Glaciation and Preglacial Remnants of an Ancient Weathering Front in Northwestern Argentina
(Springer, 2014)
A record of glacier advance and retreat is preserved in Carboniferous strata exposed in an exhumed glacial paleovalley on the eastern side of the Paganzo basin. Previous investigations have focused on the sandstones in the ...

Cronología depositacional del miembro inferior de la Formación Toro Negro, antepaís andino, La Rioja, ArgentinaDepositional chronology of the lower member of the Toro Negro Formation (Mio-Pliocene), Andean Foreland, La Rioja
(Asociación Geológica Argentina, 2020-01)
Se presenta un análisis integrado de la magnetoestratigrafía reinterpretada, a partir de los datos de Ré (2008), en función de nuevas edades U-Pb obtenidas por Amidon et al. (2016), con modelos de estratigrafía secuencial ...
