An alternative Mesozoic geodynamic model for the evolution of the Central Coastal ranges of Peru: the Rio Cañete Basin
(Sociedad Geológica del Perú - SGPPE, 2021-11)
Integration of detailed stratigraphic, sedimentologic and tectonic studies of the Río Cañete Basin with opening and divergence rates of the South Atlantic Ocean, overriding plate velocity, trench migration, subducting age ...
The last mangroves of Marajo Island - Eastern Amazon: Impact of climate and/or relative sea-level changes
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The dynamics, over the last 7500 years, of a mangrove at Marajo Island in northern Brazil were studied by pollen and sedimentary facies analyses using sediment cores. This island, located at the mouth of the Amazon River. ...
Structure and tectonics of the central Chilean margin (31 degrees-33 degrees S): implications for subduction erosion and shallow crustal seismicity
(Oxford University Press, 2015)
The pre- and current collision of the Juan Fernandez Ridge with the central Chilean margin at 31 degrees-33 degrees S is characterized by large-scale crustal thinning and long-term subsidence of the submarine forearc caused ...

Assessing the effect of sea-level change and human activities on a major delta on the Pacific coast of northern South America: The Patía River
(ELSEVIER SCIENCE BV, 2012-05-15)
This paper presents the main physical and human-induced stresses that have shaped the recent evolution of the Patía River delta, the largest and best-developed delta on the western margin of South America. During the ...
Geodynamic conditions resulting from the 2010 earthquake and tsunami in the coast of central Chile. The case of Pichilemu Condiciones geodinámicas derivadas del terremoto y tsunami de 2010 en la costa de Chile central. El caso de Pichilemu
(Revista de Geografia Norte GrandeAvda.Vicuna Mackenna 4860Macul-Santiago, 2015)
© 2015, Revista de Geografia Norte Grande, All rights reserved.The earthquake and tsunami of 2010, triggered changes in the geomorphological and sedimentary dynamics along the coast of Pichilemu, in central Chile. These ...
Seismic structure of the north-central Chilean convergent margin: Subduction erosion of a paleomagmatic arc
(AGU, 2014)
We study the erosive convergentmargin of north-central Chile (at ~31°S) by using high-resolution
bathymetric, wide-angle refraction, and multichannel seismic reflection data to derive a detailed
tomographic 2-D velocity-depth ...
Thermochronology and landscape evolution of the Serra do Caparaó region, an onshore segment of the Brazilian South Atlantic continental margin
(Universidade Federal de Minas GeraisBrasilIGC - DEPARTAMENTO DE GEOLOGIAPrograma de Pós-Graduação em GeologiaUFMG, 2022-04-27)
The origin and evolution of elevated passive continental margins have intrigued geoscientists since their prominent topography is more reasonably explained in the context of an active rift than a mature `passive’ setting. ...
Active Deformation, Uplift and Subsidence in Southern South America Throughout the Quaternary: A General Review About Their Development and Mechanisms
(Springer, 2016)
A broad range of processes act today and have acted simultaneously during the Quaternary, producing relief from the Chilean coast, where the Pacific Ocean floor is sinking underneath the South American margin, to the ...
