Quaternary glaciolacustrine deposits around a Triple Junction site: Paleolakes at the foot of the Northern Patagonian Ice field (Argentina and Chile)
(Servicio Nacional de Geología y Minería, 2020-05)
The area involved by the triple junction between the South American, Nazca and Antarctic plates activity was affected by Quaternary glaciations. Before 12,800 yrs BP an extended ice field occupied the top of the Patagonian ...
Tectonic and climatic controls on the late Pleistocene to Holocene evolution of Paleolake Ullum-Zonda in the Precordillera of the central Andes, Argentina
(Academic Press Inc Elsevier Science, 2017-09)
The Ullum-Zonda tectonic depression located in the central Andes Precordillera records several lacustrine episodes from frequent natural damming of the San Juan River during the late Quaternary. We analyzed stratigraphic, ...
Chronology, stratigraphy and hydrological modelling of extensive wetlands and paleolakes in the hyperarid core of the Atacama Desert during the late quaternary
(Elsevier Ltd, 2018)
© 2018 Elsevier LtdThe halite-encrusted salt pans (salars) present at low elevations in the hyperarid core of the Atacama Desert in northern Chile are unique features of one of the driest and possibly oldest deserts on ...
Holocene ochreous lacustrine sediments within the Famatina Belt, NW Argentina: A natural case for fossil damming of an acid drainage system
(Pergamon-Elsevier Science Ltd, 2014-04)
A 44m-thick lacustrine succession of silty-clay banded ochres and subordinated sandstones, and conglomerates (known as the Corral Amarillo Formation) is superbly exposed within the Famatina Belt (Central Andes of Argentina) ...
Characterization of the sedimentary deposits of cÁssia and its relationship with the cÁssia fault zone, southwest of minas geraisCaracterização dos depósitos sedimentares de cássia e sua relação com a zona de falha de cássia, sudoeste de minas gerais
(2019-01-01)
The sedimentary deposits of the Cássia region in southwestern Minas Gerais are known and intensely exploited as raw material for red ceramics since the 1930s. However, such geological materials have been poorly studied, ...

Paleolacustrine records from Late Pleistocene – Holocene in the Perito Moreno National Park, Argentinian Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2017-04)
The reconstruction of glacial paleolake formation and evolution allows the understanding of glacier advance and retreat behavior for longer periods of time. New datings obtained from paleolacustrine deposits in the Argentinian ...
Cosmogenic dating of rock avalanches constraining Quaternary stratigraphy and regional neotectonics in the Argentine Central Andes (32° S)
(Pergamon-Elsevier Science Ltd, 2015-03)
This paper provides a comprehensive review of the chronostratigraphy of six rock avalanches clustered in the northern extreme of the Cordon del Plata range. These rock avalanches are stratigraphically related to Pleistocene ...
Geophysical methods applied to Quaternary studies in glacial environments: Río Valdez outcrop, Tierra del Fuego, Argentina
(Pergamon-Elsevier Science Ltd, 2019-08-10)
In the Río Valdez mouth, located in the southeastern coast of Fagnano lake, Tierra del Fuego, an outcrop of 7 m thick lacustrine sediments was identified. Taking into account geomorphological and sedimentological surveys, ...
