The geological and structural evolution of the long-lived Miocene-Pleistocene La Hoyada Volcanic Complex in the geodynamic framework of the Central Andes, Argentina
(Elsevier Science, 2018-07)
The long-lived La Hoyada Volcanic Complex (LHVC) is located in the east of Cordillera de San Buenaventura in Argentina. This region is important for understanding of the geodynamic evolution of the Southern Puna, since it ...
Stratigraphic architecture and paleosols as basin correlation tools of the early Paleogene infill in central–south Patagonia, Golfo San Jorge Basin, Argentinean Patagonia
(Pergamon-Elsevier Science Ltd, 2020-04)
The Paleogene infill of the eastern Golfo San Jorge Basin, Patagonia, Argentina, is composed of marine and terrestrial deposits. The latter are fluvial, pedogenically modified successions interlayered with eolian volcaniclastic ...
Comments on the paper “Reconnaissance of Upper Jurassic Morrison Formation ichnofossils, Rocky Mountain Region, USA: Paleoenvironmental, stratigraphic, and paleoclimatic significance of terrestrial and freshwater ichnocoenoses” by Stephen T. Hasiotis
(Elsevier Science, 2007-12)
Hasiotis (2004) has described and interpreted a relatively diverse and potentially very interesting ichnofauna from the Upper Jurassic Morrison Formation of the western United States. An effort was made by the author to ...
Aimé Bonpland's drawings of Itá Pucú, 1834, and the history of early geological representations in Argentina
(History Earth Sciences Society, 2004-01)
The early geological representations in Argentina dated from the middle of the nineteenth century when Alcide d'Orbigny, Charles Darwin, Bartholomew James Sulivan, Franz Foetterle, Auguste Bravard, Jakob Christen Heusser ...
Stratigraphic record of river-dominated crevasse subdeltas with tidal influence (Lajas Formation, Argentina)
(Society for Sedimentary Geology, 2015-03)
Crevasse subdeltas develop on modern river-dominated delta plains, and may be affected by the interaction of river currents and marine processes. However, their sedimentology and stratigraphic architecture is poorly ...
Recognizing drainage reorganization in the stratigraphic record of the Neogene foreland basin of the Central Andes
(Elsevier Science, 2020-07)
Changes in drainage basin reorganization as preserved in the stratigraphic record have direct implications for the composition, organization, and scaling relationships of sedimentary systems. However, isolating the ...
Non-depositional and erosional “offshore” bioeroded hardgrounds from the Lower Cretaceous of the Neuquén Basin, Argentina: Insights into their sequence-stratigraphic implications and controls
(Elsevier, 2019-06)
Hardgrounds are important surfaces for basin analysis and oil exploration, representing in some cases significant markers of the sedimentary basin fill. In the Neuquén Basin, bioerosion structures are common on the shell ...
Sedimentologic and stratigraphic evolution of the Cacheuta basin: Constraints on the development of the Miocene retroarc foreland basin, south-central Andes
(Geological Society of America, 2018-06)
Retroarc foreland basins in contractional arc settings contain evidence of temporal and spatial variations in magmatic activity, deformation, and exhumation along the continental margin and serve as excellent recorders of ...
Sequence stratigraphic analysis of Cenomanian greenhouse palaeosols: a case study from southern Patagonia, Argentina.
(Elsevier Science, 2012-10)
The aim of this contribution is to analyse extrinsic (i.e., tectonics, climate and eustasy) and intrinsic (i.e., palaeotopography, palaeodrainage and relative sedimentation rates) factors that controlled palaeosol development ...
Discriminating intra-parasequence stratigraphic units from two-dimensional quantitative parameters
(Society for Sedimentary Geology, 2021-08)
The intra-parasequence scale is still relatively unexplored territory in high-resolution sequence stratigraphy. The analysis of internal genetic units of parasequences has commonly been simplified to the definition of ...
