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 ...

Geochemistry of Modern Sediments from San Quintín Coastal Lagoon, Baja California: Implication for Provenance
(Revista Mexicana de Ciencias Geológicas, 2009-01-01)
A detailed regional grid of 97 surficial sediment samples is studied for the San Quintín coastal lagoon, which is a shallow embayment located adjacent to a “regionally-rare” intraplate-type basaltic terrain known as San ...
Geochronology, sedimentology and paleosol analysis of a Miocene, syn-orogenic, volcaniclastic succession (La Pava Formation) in the north Patagonian foreland: Tectonic, volcanic and paleoclimatic implications
(Pergamon-Elsevier Science Ltd, 2020-06)
The initial infill of the Patagonian Broken Foreland is related to Miocene, syn-orogenic, volcaniclastic successions accommodated in intermontane basins. In the last years several works have paid attention to these successions ...
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 ...
Synsedimentary ash rains and paleoenvironmental conditions during the deposition of the Chachil Formation (Pliensbachian) at its type locality, Neuquén Basin, Argentina
(Pergamon-Elsevier Science Ltd, 2016-11)
A detailed sedimentological analysis of the so called “Chachil Limestones” at its type locality around the Mirador del Chachil area, southwestern Neuquen province, Argentina, is presented in this paper for the first time. ...
Middle-Late Jurassic megaflora of laguna Flecha Negra locality in Santa Cruz province, Patagonia, and floristic assemblages of the Bahía Laura complex
(Pergamon-Elsevier Science Ltd, 2020-06)
A Middle-Late Jurassic fossil plant assemblage is described from the Bahía Laura Complex at the Laguna Flecha Negra locality, Santa Cruz Province. The fossil assemblage is autochthonous, preserved in volcaniclastic sediments ...
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 ...
