Estratigrafia de seqüências das formações Taciba e Rio Bonito (Membro Triunfo) na região de Mafra/SC, leste da Bacia do Paraná
(2004-11-01)
The Taciba and Rio Bonito (lower Triunfo Mbr) formations are divided into six depositional sequences based on cores, gamma-ray and electrical logs from shallow drillings from northern Santa Catarina State, Each sequence ...
High resolution isotopic ages for the early Miocene "Patagoniense" transgression in Southwest Patagonia: Stratigraphic implications
(Pergamon-Elsevier Science Ltd, 2012-10)
The classical marine Patagoniense succession at Lago Argentino, southwestern Patagonia (Argentina), known as Estancia 25 de Mayo Formation, was dated by radiometric U-Pb on zircon grains from pyroclastic rocks and 87Sr/ ...
Ecophylogeography of the disjunct South American xerophytic tree species Prosopis chilensis (Fabaceae)
(Wiley Blackwell Publishing, Inc, 2020-03)
The intraspecific evolutionary history of South American xerophytic plant species has been poorly explored. The tree species Prosopis chilensis has a disjunct distribution in four South American regions: Southern Peru, ...
A late Eocene-early Oligocene transgressive event in the Golfo San Jorge basin: palynological results and stratigraphic implications
(Elsevier, 2015-08-18)
A new Cenozoic dataset in the subsurface of the South Flank of the Golfo San Jorge Basin (Santa Cruz province) allowed to identify a non-previously recognized transgressive event of late Eocene to early Oligocene age. Below ...
Sr-stratigraphy and sedimentary evolution of early Miocene marine foreland deposits in the northern Austral (Magallanes) Basin, ArgentinaEstratigrafía de Sr y evolución sedimentaria de los depósitos marinos del Mioceno temprano en el antepaís del norte de la Cuenca Austral (o Magallanes), Argentina
(Servicio Nacional de Geología y Minería, 2015-09)
Early Miocene shallow marine deposits in the region of Lago Posadas-Meseta Belgrano (Argentina) represent part of the “Patagoniense” transgression, an Atlantic marine incursion that flooded large part of Patagonia, including ...
Sharks (Neoselachii) and palynomorphs from Mendoza (Argentina): new evidence of the Late Cretaceous Atlantic marine transgression
(Taylor & Francis Ltd, 2013-12-10)
Neoselachian (modern shark) teeth and palynomorphs have been recovered from the Late Cretaceous Jagüel Formation in the Province of Mendoza, Argentina. The fossiliferous beds were deposited during the Atlantic transgression ...
Late Pleistocene and Holocene geomorphologic evolution of Laguna Las Vueltas area, Tierra del Fuego (Argentina)Evolución geomorfológica del área de Laguna Las Vueltas (Tierra del Fuego, Argentina) durante el Pleistoceno tardío y Holoceno
(Servicio Nacional de Geología y Minería, 2020-01)
El área de Laguna Las Vueltas (LLV) conserva la morfología de una cuenca hídrica del Pleistoceno tardío que fue inundada durante la transgresión marina del Holoceno medio. Los sedimentos asociados con un paleosuelo datado ...
Tectonic controls on the Maastrichtian-Danian transgression in the Magallanes-austral foreland basin (Chile): implications for the growth of the southern patagonian Andes
(Elsevier, 2020)
The Maastrichtian-Danian transgression was one of the most extensive Atlantic-derived marine incursions in Patagonia. This study examines its stratigraphic record and origin in the Magallanes-Austral Basin, revealing an ...
The fate of the Farallon slab beneath Patagonia and its links to Cenozoic intraplate magmatism, marine transgressions and topographic uplift
(Elsevier Science, 2020-11)
The arrival and subsequent stagnation of the Farallon/Nazca slab at the mantle transition zone below southern South America triggered seemingly unrelated large-scale geological processes in the second half of the Cenozoic. ...
