Late Cenozoic topographic evolution of the Eastern Cordillera and Puna Plateau margin in the southern Central Andes (NW Argentina)
(Elsevier Science, 2020-04)
The Andes constitute an important orographic barrier in the southern hemisphere, impacting atmospheric circulation, the amount and distribution of rainfall, and Earth-surface processes in a highly asymmetric manner. In the ...
Palynological evidence of the geoecological belts dynamics from Eastern Cordillera of NW Argentina (23° S) during the Pre-Last Glacial MaximumEvidencias palinológicas de la dinámica de los pisos geoecológicos de la cordillera oriental del noroeste Argentino (23° S) durante el Pre Último Máximo Glacial
(Servicio Nacional de Geología y Minería, 2016-05)
This paper presents the first palynological record for the dynamics of geoecological belts of the Eastern Cordillera in northwestern Argentina prior to the Last Glacial Maximum (LGM). The study was carried out on a 5-m ...

(UNIVERSIDAD NACIONAL DE COLOMBIA, 2005)
Paipa volcano products are mainly pyroclastic pumice and ash flow tuffs, lava domes and pyroclastic block and ash flow tuffs. They are classified as alkaline rhyolites and trachytes and high-K calcalkaline rhyolites. ...
Development of an incipient Paleogene topography between the present-day Eastern Andean Plateau (Puna) and the Eastern Cordillera, southern Central Andes, NW Argentina
(Wiley Blackwell Publishing, Inc, 2020-09-25)
The structural and topographic evolution of orogenic plateaus is an important research topic because of its impact on atmospheric circulation patterns, the amount and distribution of rainfall, and resulting changes in ...

Late Miocene fluvial strata of the Palo Pintado Formation are broadly exposed to the northwest of the town of Angastaco, Salta province, Northwest of Argentina. These strata accumulated in the extensional Angastaco Basin. ...
The fracture patterns of the Tin Tin anticline: Fracturing process during the foreland evolution in the Calchaquí Valley, northwestern Argentina
(Pergamon-Elsevier Science Ltd, 2017-03)
We present a field-based work which illustrates the fracture patterns of the carbonate-silicoclastic Yacoraite Formation in the Tin Tin anticline, a basement fault-related fold located in southern part of the Eastern ...
Biogeographic reconstruction of the migratory Neotropical fish family Prochilodontidae (Teleostei: Characiformes)
(2022-01-01)
Geographically, widespread Neotropical fish lineages offer opportunities to reconstruct historical biogeography patterns and infer processes leading to modern ichthyological diversity and distribution. The characiform ...
A climatic trigger for catastrophic Pleistocene–Holocene debris flows in the Eastern Andean Cordillera of Colombia
(2015)
The geomorphology and stratigraphy of massive debris flows on the Eastern Andean Cordillera, Colombia, indicate two distinct deposits can be recognized. The lower Chinauta deposit covers 14 km2 and has a thickness of ∼60 m, ...
