Variaciones glaciales durante el Holoceno en Patagonia Central, Aisén, Chile: evidencias geomorfológicas Holocene glacial variations in Central Patagonia, Aisén, Chile: geomorphological evidences

open access: yesAndean Geology, 2011
Durante el Holoceno, avances y retrocesos glaciares geomorfológicamente registrados caracterizan la Patagonia. Este artículo presenta la evolución geomorfológica y las evidencias de fluctuaciones glaciales holocénicas de una región patagónica, que ...

Lower Jurassic to Early Paleogene Intraplate Contraction in Central Patagonia

open access: yes, 2018
Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onward, a process that was interrupted by the Andean Orogeny. New data generated from the hydrocarbon exploration allowed identifying Jurassic to Eocene contractional deformations ...

Rock glaciers in central Patagonia [PDF]

open access: yesGeografiska Annaler: Series A, Physical Geography, 2018
Active rock glaciers are ice and debris-cored landforms common in cold arid mountains. They have not been widely described in the Patagonian Andes of southern South America and here we provide the ...

Regional mid-Pleistocene glaciation in central Patagonia [PDF]

open access: yesQuaternary Science Reviews, 2017
Southern South America contains a glacial geomorphological record that spans the past million years and has the potential to provide palaeoclimate information for several glacial periods in Earth's history. In central Patagonia, two major outlet glaciers of the former Patagonian Ice Sheet carved deep basins ∼50 km wide and extending over 100 km into ...

The signature of river- and wind-borne materials exported from Patagonia to the southern latitudes: a view from REEs and implications for paleoclimatic interpretations [PDF]

open access: yes, 2004
Riverine and wind-borne materials transferred from Patagonia to the SW Atlantic exhibit a homogeneous rare earth element (REE) signature. They match well with the REE composition of Recent tephra from the Hudson volcano,and hence this implies a ...

Holocene history of río tranquilo glacier, monte San Lorenzo (47°S), Central Patagonia [PDF]

open access: yes, 2021
The causes underlying Holocene glacier fluctuations remain elusive, despite decades of research efforts. Cosmogenic nuclide dating has allowed systematic study and thus improved knowledge of glacier-climate dynamics during this time frame, in part by ...

Recent increase in autumn temperature has stabilized tree growth in forests near the tree lines in Chilean Patagonia

open access: yesEcosphere, 2022
It is widely accepted that global warming is affecting forests near the tree line by increasing tree growth in these cold‐limited environments. However, since about 1970, a reduction in tree growth near the tree line has been observed in response to ...

Preliminary Appraisal of a Correlation Between Glaciations and Large Igneous Provinces Over the Past 720 Million Years

open access: yesGeophysical Monograph Series, Page 169-190., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
