The coastal ridge sequence at Rio Grande do Sul: A new geoarchive for past climate events of the Atlantic coast of southern Brazil since the mid Holocene
(Pergamon-Elsevier Science Ltd, 2017-05)
We present here the first geochronometric analysis of a large succession of coastal ridges that developed south of Rio Grande do Sul inlet, aided by OSL dating of samples taken in this succession that amounts c. 306 coastal ...
Seismic ridge subduction and topography: Foreland deformation in the Patagonian Andes
(Elsevier Science, 2005-04)
The Patagonian Andes recorded several episodes of active ridge subduction in the last 80 million years. An analysis of the spatial and temporal relation between the present segment of collision of the Chile ridge and the ...
Asymptotic regimes of ridge and rift formation in a thin viscous sheet model
(American Institute of Physics, 2008-04)
We numerically and theoretically investigate the evolution of the ridges and rifts produced by the convergent and divergent motions of two substrates over which an initially uniform layer of a Newtonian liquid rests. We ...
Geomorphology and internal architecture of Holocene sandy-gravel beach ridge plain and barrier spits at Río Chico area, Tierra del Fuego, Argentina
(Pergamon-Elsevier Science Ltd, 2018-07)
The internal architecture and processes involved in the development of paraglacial sandy-gravel beach ridges and barrier spits have been analyzed by interpretation of ground-penetrating radar (GPR) records, satellite images ...
The subduction of the Copiapó aseismic ridge, is the causing of the formation of metallic minerals deposits in north of Chile and Argentina?
(Elsevier, 2019-11)
The results obtained in this work evince that the metallic mineral deposits located in the northern region of the Chilean-Pampean flat slab (in northern Chile and north-western Argentina), at approximately 27 300 S, would ...
On a new species of Isomeria Beck and redescription of species of
(Magnolia Press, 2006-12)
The Camaenid genera Labyrinthus Beck, 1837 and Isomeria Beck, 1837 are mainly distributed in northern South America. Current anatomical information available for both genera is scarce, particularly that concerning Isomeria ...
Southward-Directed Subduction of the Farallon–Aluk Spreading Ridge and Its Impact on Subduction Mechanics and Andean Arc Magmatism: Insights From Geochemical and Seismic Tomographic Data
(Frontiers Research Foundation, 2020-05)
Since the initial proposal of the past existence of a southward-directed mid-ocean ridge–subduction interaction in the Andes during Late Cretaceous–Paleogene times, several studies have been devoted to uncover the ...
The asymmetry of dermatoglyphic finger ridge counts and the geographic altitude of the Jujenean population in northwest Argentina
(Elsevier, 2018-11)
Asymmetry is omnipresent in the living world and therefore is a measure of developmental noise and instability. The main stressing agent in high-altitude ecosystems is hypobaric hypoxia. The variation in bilateral ...
Trench-parallel spreading ridge subduction and its consequences for the geological evolution of the overriding plate: Insights from analogue models and comparison with the Neogene subduction beneath Patagonia
(Elsevier Science, 2018-07)
A series of 3-D asthenospheric-scale analogue models have been conducted in the laboratory in order to simulate the arrival of a spreading ridge at the trench and understand its effect on plate kinematics, slab geometry, ...
Seismotectonic implications of the South Chile ridge subduction beneath the Patagonian Andes
(Wiley Blackwell Publishing, Inc, 2021-02-14)
The South Chile ridge (SCR) intersects the Patagonian trench around 46°09′S, forming the triple junction among the Antarctic, Nazca, and South America plates. Subduction of the SCR since ~18 Ma produced the opening of a ...
