The alluvial architecture of a suspended sediment dominated meandering river: the Río Bermejo, Argentina
(Wiley Blackwell Publishing, Inc, 2016-03)
The alluvial architecture of fine-grained (silt-bed) meandering rivers remainspoorly understood in comparison to the extensive study given to sand-bed andgravel-bed channels. This paucity of knowledge stems, in part, from ...
The sedimentology and alluvial architecture of a large braid bar, Río Paraná, Argentina
(Society for Sedimentary Geology, 2009-07)
This paper presents ∼ 30 km of ground penetrating radar (GPR) data from a mid-channel bar in the sixth largest river in the world, the Rio Paraná, Argentina. GPR profiles, with depth of penetration up to 12 m below the bar ...
The Quaternary alluvial systems tract of the Pantanal Basin
(2015-01-01)
The Pantanal Basin is an active sedimentary basin in central-west Brazil that consists of a complex alluvial systems tract characterized by the interaction between different river systems developed in one of the largest ...
Architecture and development of the alluvial sediments of the Upper Jurassic Tordillo Formation in the Cañada Ancha Valley, northern Neuquén Basin, Argentina
(Elsevier Science, 2009-07)
The Upper Jurassic Tordillo Formation at Cañada Ancha area, northern Neuquén Basin, Argentina, comprises a multi-stage suit of predominantly alluvial sediments that is heterolithic in nature. In that suit, several lithofacies, ...
Alluvial-eolian interaction in a Cambrian rift margin: the Pedra das Torrinhas and Pedra Pintada formations (Guaritas Group, RS)
(Academia Brasileira de Ciências, 2009)
This work presents a study of selected outcrops from the Pedra das Torrinhas Formation of the Guaritas Group (Cambrian, Camaquã Basin), near the basin bordering Encantadas Fault Zone. The studied succession includes alluvial ...
Complex alluvial architecture, paleohydraulics and controls of a multichannel fluvial system: Bajo Barreal Formation (Upper Cretaceous) in the Cerro Ballena anticline, Golfo San Jorge Basin, Patagonia
(Pergamon-Elsevier Science Ltd, 2018-08)
A sedimentological-architectural review, and a palaeohydrological study was performed in a 380 m thick succession of the Bajo Barreal Formation (Upper Cretaceous) in the Cerro Ballena anticline, Golfo San Jorge Basin, ...
HOLOCENE ALLUVIAL DEPOSITS MEANING IN A SEMI-ARID ENVIRONMENT: A CASE STUDY ON SERTANEJA DEPRESSION (BAHIA STATE/BRAZIL)
(Uniao Geomorfologia Brasileira, 2019-10-01)
Ephemeral drainage basins and their alluvial deposits may have characteristics that contribute to the understanding of Holocene time-scale climate dynamics. Although widely studied in semiarid contexts of different countries, ...
Sedimentology and alluvial architecture of the Bajo Barreal Formation (Upper Cretaceous) in the Golfo San Jorge Basin: outcrop analogues of the richest oil-bearing fluvial succession in Argentina
(Elsevier, 2016-04)
This study addresses the sedimentology, architecture and dimensions of fluvial deposits in the Bajo Barreal Formation (Upper Cretaceous) in the Codo del Senguerr anticline, Golfo San Jorge Basin, Argentina. The stratigraphic ...
Ambientes deposicionais e evoluÇÃo estratigrÁfica do cretÁceo superior da bacia dos parecis
(2014-01-01)
Although there are many publications about the Brazilian Cretaceous basins, the understanding of tectonic and climatic processes concerned in the evolution of continental sequences still needs studies, especially those ...
