Flux and provenance of ice-rafted debris in the earliest Pleistocene sub-polar North Atlantic Ocean comparable to the last glacial maximum
(Amsterdam, 2012-07-13)
Relatively little is known in detail about the locations of the early Pleistocene ice-sheets responsible for ice-rafted debris(IRD) inputs to the sub-polar North Atlantic Ocean during intensification of northern hemisphere ...
Dropstones in the Mar del Plata Canyon Area (SW Atlantic): Evidence for Provenance, Transport, Distribution, and Oceanographic Implications
(American Geophysical Union, 2021-01)
A variety of gravel- to cobble-sized rocks, recovered from the Mar del Plata (MdP) Canyon area (Western South Atlantic at 38°S) and interpreted as ice-rafted debris, represent the first evidence that large icebergs have ...
Transformation, partitioning and flow–deposit interactions during the run-out of megaflows
(Wiley Blackwell Publishing, Inc, 2017-02)
Four megabeds (I to IV) were recognized throughout the Cerro Bola inlier, a glacially influenced depositional area of the Carboniferous Paganzo Basin, south-western La Rioja Province, Argentina. Such anomalous thick beds ...
Relación entre variaciones isotópicas de 18O y 2H de agua intersticial en testigos de sedimento y dinámica del frente del glaciar Europa, Campos de Hielo Sur, Chile.
(Universidad de Concepción.Facultad de Ciencias QuímicasDepartamento de Ciencias de la Tierra., 2021)
Los Campos de Hielo Sur corresponden a las más grandes masas de hielo temperadas en el hemisferio sur.
Muchos de los glaciares que lo componen se encuentran en retroceso desde su máxima extensión glaciar

O grupo itararé (Neocarbonífero-eopermiano) entre porto amazonas (PR) e mafra (SC): Sedimentação gravitacional em contexto marinho deltaico com influência glacial
(2014-01-01)
Gravitational sedimentation from the permocarboniferous section of Paraná Basin is well known although still understudied. Mass-transport deposits (MTDs) as debris flows and slumps, beside turbidites, predominantly ...
Life in the late Paleozoic ice age: Trace fossils from glacially influenced deposits in a late carboniferous fjord of western Argentina
(Paleontological Society, 2011-05)
The early Late Carboniferous rocks of the Guandacol Formation in western Argentina preserve the glacial to postglacial transition. In the study area, this unit has been divided in three intervals: 1) a lower diamictitic ...

Inter- and intratill boulder pavements in the Carboniferous Hoyada Verde Formation of West Argentina: An insight on glacial advance/retreat fluctuations in Southwestern Gondwana
(Elsevier Science, 2016-04)
Two glacially abraded surfaces have been identified in the glaciomarine section of the Carboniferous Hoyada Verde Formation, Calingasta-Uspallata basin in west Argentina. The Glacial Erosion Surfaces (GES) found in the ...
Climate-driven changes in sedimentation rate influence phosphorus burial along continental margins of the northwestern Mediterranean
(Elsevier, 2018)
The burial of phosphorus (P) in continental margin sediments is a critical component of the marine reactive P budget, and thus an important factor in marine biological productivity. We determined downcore records of P from ...
