Morphology-physiology of two morpho of the genus Durvillaea in the sub-Antarctic ecoregion of Chile
(2016)
The Chilean Sub-Antarctic ecoregion is influenced by three oceans: Pacific, Atlantic and Southern, and it
is characterized by its environmental heterogeneity (fjords, channels and post-glacial lakes), which result
from ...
Geomorphological Features of the Galeras Volcanic Complex
(SPRINGER, 2016-01-01)
The Galeras volcanic complex, near the city of Pasto, was formed in several steps. At similar to 560 ka, BP a major caldera (the Coba Negra Caldera) appeared with its center similar to 5 km west of the present-day active ...
Bivalves from the carboniferous glacial deposits of central Patagonia
(Philipps-Universität Marburg. Geologisch-paläontologisches Institut, 2010-12)
Carboniferous deposits of central Patagonia afford important evidence on the range and origin of various components of the endemic bivalve fauna of Gondwana, but the available material of some interesting forms is unfortunately ...
Landscape evolution in the Guañacos fold and thrust belt (37° S): Insights from geomorphological and morphometric analysis
(Pergamon-Elsevier Science Ltd, 2021-11)
The Guañacos fold and thrust belt, in the northern Neuquén Andes (37°-38°S; 70°30′-71°10′W), has been studied by many researchers focusing on the Quaternary tectonic activity, from a morphological to a structural perspective. ...
Relict glacial landscape in the Sierra Baguales Mountain Range (50°-51° S): evidence of glaciation dynamics and types in the eastern foothills of the southern Patagonian Andes.
(2017)
The glacial morphology of southern South American presents invaluable evidence to reconstruct former glacier behaviour and its relation to climate and environmental changes. However, there are still spatial and temporal ...
Molecular diversity and historical phylogeography of the widespread genus Mastiglanis (Siluriformes: Heptapteridae) based on palaeogeographical events in South America
(Oxford Univ Press, 2021-12-16)
The catfish family Heptapteridae, endemic in the Neotropical region, is composed of small- to medium-sized species. The genus Mastiglanis was monotypic until very recently and is often misidentified as Imparfinis because ...
The Argentine continental shelf: morphology, sediments, processes and evolution since the Last Glacial Maximum
(Geological Society, 2014-10)
The Argentine continental shelf is one of the largest and smoothest siliciclastic shelves in the world. Although it is largely emplaced in a passive continental margin, the southernmost regions are related to transcurrent ...
Unravelling hidden glacial effects in the Cryogenian marine depositional settings of the Tandilia Basin, Argentina
(Elsevier Science, 2021-08)
The Cryogenian Period (720–635 Ma) is wide known by the occurrence of two global glaciations, Sturtian and Marinoan, responsible of dramatic climate and sea level changes as well as seawater oxygenation events. Constrained ...
Mio-Pliocene glaciations of Central Patagonia: New evidence and tectonic implications
