Geomorphologic and Glacial Evolution of the Cachapoal and southern Maipo catchments in the Andean Principal Cordillera, Central Chile (34°-35° S)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2019)
We present here a reconstruction of the post late Miocene landscape evolution of the western slope of the Andean Cordillera Principal near 34°20’ S. We base our analysis on the available geological information, a morphological ...
Late Quaternary Activity of the La Rinconada Fault Zone, San Juan, Argentina
(American Geophysical Union, 2019-03)
Most of the permanent deformation in the Pampean Flat slab segment of the central Andes is taken up at the Andean Orogenic Front in Argentina, a narrow zone between the Eastern Precordillera and Sierras Pampeanas that ...
100 kyr fluvial cut-and-fill terrace cycles since the Middle Pleistocene in the southern Central Andes, NW Argentina
(Elsevier Science, 2017-09)
Fluvial fill terraces in intermontane basins are valuable geomorphic archives that can record tectonically and/or climatically driven changes of the Earth-surface process system. However, often the preservation of fill ...
Teleconnections between boreal cooling and tropical glaciers in the Cordillera Blanca (Peru)
(International Permafrost AssociationPE, 2019)
30 samples have been collected for the cosmogenic dating of expanding and shrinking glacial phases southwesternward of Nevado Hualcán (9º, 12'S; 77º, 31'W, 6122 m), in the Cordillera Blanca (Peru).The set includes 28 moraine ...
Cosmogenic record of the evolution of tropical glaciers In the Piticocha Valley – Pariaqaqa mountain range (Lima - Peru)
(Universidad de Ingeniería y TecnologíaPE, 2019-08)
The Piticocha Valley is located on the southwest side of Pariaqaqa Peak (11 ° 59'39.53 "S; 75 ° 59'35.74" W; 5758 m.s.n.m) in the Western Central Andes. 35 samples of moraines blocks and rock beds were obtained, to be dated ...

En este trabajo se presentan los resultados del análisis tafonómico efectuado en el depósito Yegua Quemada 3, Parque Nacional Monte León, con una ubicación cronológica correspondiente al Holoceno medio. Los resultados ...
Glacier fluctuations in the northern Patagonian Andes (44°S) imply wind-modulated interhemispheric in-phase climate shifts during Termination 1
(2022)
The Last Glacial Termination (T1) featured major changes in global circulation systems that led to a shift from glacial to interglacial climate. While polar ice cores attest to an antiphased thermal pattern at millennial ...
