Recognition criteria, characteristics and implications of the fluvial to marine transition zone in ancient deltaic deposits (Lajas Formation, Argentina)
(Wiley Blackwell Publishing, Inc, 2016-12)
The seaward end of modern rivers is characterized by the interactions of marine and fluvial processes, a tract known as the fluvial to marine transition zone, which varies between systems due to the relative strength of ...
Fluvial architecture variations linked to changes in accommodation space: Río Chico Formation (Late Paleocene), Golfo San Jorge basin, Argentina
(Elsevier Science, 2013-08)
The Upper Paleocene Río Chico Formation is a 50-180. m thick fluvial succession developed in a passive-margin setting, Golfo San Jorge basin, Central Patagonia, Argentina. A detailed description and interpretation of ...
Seismites as a tool in the palaeoenvironmental reconstruction of fluvial deposits: The Cambrian Guarda Velha Formation, southern Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Soft-sediment deformation (SSD) is widely described in the literature, but there is no clear consensus regarding its origin and significance. Existing models for SSD in fluvial sediments do not clearly demonstrate a ...
Architecture of an Oligocene fluvial ribbon sandstone in the Ebro Basin, North-eastern Spain
(Wiley, 2010-04)
Fluvial ribbon sandstone bodies are ubiquitous in the Ebro Basin in North-eastern Spain; their internal organization and the mechanics of deposition are as yet insufficiently known. A quarrying operation in an Oligocene ...
Reconstructing fluvial bar surfaces from compound cross-strata and the interpretation of bar accretion direction in large river deposits
(Wiley-Blackwell, 2016)
The interpretation of fluvial styles from the rock record is based for a significant part on the identification of different types of fluvial bars, characterized by the geometric relationship between structures indicative ...
Ground Penetrating Radar investigation of depositional architecture: the Sao Sebastiao and Marizal formations in the Cretaceous Tucano Basin (Northeastern Brazil)
(Soc Brasileira Geologia, 2016)
One key factor for the advance in the study of fluvial deposits is the application of geophysical methods, being the Ground Penetrating Radar one of special value. Although applied to active rivers, the method is not ...
