Volcaniclastic sedimentation influenced by logjam breakups? An example from the Blanco River, Chile
(Pergamon-Elsevier Science Ltd, 2020-03)
The Blanco River drains the southern flank of the Chilean Chaitén volcano toward the Pacific Ocean. During 2008, much of the rhyolitic tephra erupted by the volcano was remobilized by this (and others) fluvial system. In ...
Sequential development of tidal ravinement surfaces in macro- to hypertidal estuaries with high volcaniclastic input: the Miocene Puerto Madryn Formation (Patagonia, Argentina)
(Springer, 2016-12)
The late Miocene beds of the Puerto Madryn Formation (Provincia del Chubut, Argentina) are formed by shallow marine and estuarine sediments. The latter include several tidal-channel infills well exposed on the cliffy coast ...
Changing fluvial styles in volcaniclastic successions: A cretaceous example from the Cerro Barcino Formation, Patagonia
(Pergamon-Elsevier Science Ltd, 2017-08)
The Cretaceous Puesto La Paloma (PLPM) and Cerro Castaño (CCM) members (Cerro Barcino Formation, Chubut Group) are pyroclastic-rich, alluvial successions deposited in the Somuncurá-Cañadón Asfalto Basin during sag and ...
Paleolandscape reconstruction and interplay of controlling factors of an Eocene pedogenically-modified distal volcaniclastic succession in Patagonia
(Pergamon-Elsevier Science Ltd, 2018-10)
The middle Eocene Koluel-Kaike Formation, located in the San Jorge Basin, Patagonia, Argentina, is a strongly pedogenically modified succession associated with volcaniclastic input in an aggrading distal eolian-dominated ...
Paleogeography of the upper Paleozoic basins of southern South America: An overview
(Pergamon-Elsevier Science Ltd, 2006-12)
The paleogeographic evolution of Late Paleozoic basins located in southern South America is addressed. Three major types of basins are recognized: infracratonic or intraplate, arc-related, and retroarc. Intraplate basins ...
Modelo de sedimentación fluvial y lacustre en el margen pasivo de un hemigraben: el Triásico de la Precordillera occidental de San Juan, República ArgentinaA model for fluvial and lacustrine sedimentation on the passive margin of a half-graben: the Triassic of the western Precordillera of San Juan, Argentine Republic
(Asociación Geológica Argentina, 2001-06)
A model for fluvial and lacustrine sedimentation on the passive margin of a half-graben: the Triassic of the western Precordillera of San Juan, Argentine Republic. Siliciclastic facies and depositional systems are studied ...
Mechanisms of aggradation in fluvial systems influenced by explosive volcanism: An example from the Upper Cretaceous Bajo Barreal Formation, San Jorge Basin, Argentina
(Elsevier Science, 2008-01)
The Late Cretaceous succession of the San Jorge Basin (Patagonia, Argentina) records different continental settings that interacted with explosive volcanism derived from a volcanic arc located in the western part of ...
Paleoenvironmental reconstruction of the coastal Monte León and Santa Cruz formations (Early Miocene) at Rincon del Buque, Southern Patagonia: a revisited locality
(Elsevier, 2015-03)
Sedimentological, ichnological and paleontological analyses of the Early Miocene uppermost Monte León Formation and the lower part of the Santa Cruz Formation were carried out in Rincón del Buque (RDB), a fossiliferous ...
