Deformación compresiva cuaternaria en la Cordillera Principal de Chile central (Cajón del Maipo, este de Santiago) [PDF]

Revista geológica de Chile, 2008
RESUMEN:El estudio geologico y estructural detallado de sedimentos recientes en el valle del rio Maipo (Cajon del Maipo), al este de Santiago, muestra la existencia de una deformacion en compresion con fallas inversas y pliegues de arrastre contemporaneos.

El Cenozoico del alto río Teno, Cordillera Principal, Chile central: estratigrafía, plutonismo y su relación con estructuras profundas [PDF]

Andean geology, 2010
The Cenozoic of the upper Teno River, Cordillera Principal, Central Chile: stratigraphy, plutonism and their relation with deep structures. The Cenozoic geologic evolution of the central part of the Cordillera Principal at ~35°S, is intimately related to the geodynamic evolution of deep crustal structures, which during different stages con- trolled the

Waveform inversion and focal mechanisms of two weak earthquakes in Cordillera Principal (Argentina) between 35° and 35.5° S [PDF]

Journal of South American Earth Sciences, 2016
Abstract Only few (six) focal mechanism, in CMT Catalog, have been so far known for intraplate shallow events in the Andean chain close to Chile–Argentina state border at latitudes ∼35° S. We add two more mechanisms, depths and moment magnitudes by carefully analyzing full waveforms of weak events recorded by broad-band stations of the Chile ...

Nuevos antecedentes estratigráficos y geocronológicos para el Meso-Cenozoico de la Cordillera Principal de Chile entre 32° y 32°30’S: Implicancias estructurales y paleogeográficas [PDF]

Andean Geology, 2014
New stratigraphical and geochronological constraints for the Mezo-Cenozoic deposits in the High Andes of central Chile between 32° and 32°30’S: Structural and palaeogeographic implications. Attempts to differentiate geological units of the Andean Principal Cordillera, between 31°30’S and 33°S, faced several problems until very recently.

Geomorphologic and Glacial Evolution of the Cachapoal and southern Maipo catchments in the Andean Principal Cordillera, Central Chile (34°-35º S)

Andean Geology, 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 characterization of the landform assemblages in the Cachapoal and southern Maipo catchments, and the first 10Be exposure ages ...

Fission track thermochronology of Neogene plutons in the Principal Andean Cordillera of central Chile (33-35°S): Implications for tectonic evolution and porphyry Cu-Mo mineralization [PDF]

Andean geology, 2009
Apatite fission track data for Miocene plutons of the western slope of the Principal Andean Cordillera in central Chile (33-35°S) define a distinct episode of enhanced crustal cooling through the temperature range of the apatite partial annealing zone (~125-60°C) from about 6 to 3 Ma.

Magnetic fabric of deformed Quaternary sediments: contributions to the understanding of the neotectonic activity in the surroundings of the Aburrá Valley, Central Cordillera, Colombia

Boletín Geológico, 2022
The origin of the Aburrá Valley (AV) is proposed as a set of coalescent tectonic subbasins located along the northern  portion of the Central Cordillera of Colombia, the Northern  Andes of Colombia.

Potencial transmisión congénita de la enfermedad de Chagas en la segunda generación de jóvenes embarazadas que asistieron a su control prenatal en el departamento de Cordillera, Paraguay

Memorias del Instituto de Investigaciones en Ciencias de la Salud
Trypanosoma cruzi es el agente causal de la enfermedad de Chagas. En Paraguay se estima que existen 165.000 personas infectadas y actualmente la principal vía de transmisión es la congénita, con una prevalencia del 5% y con alrededor de 400 niños ...

El Cenozoico del alto río Teno, Cordillera Principal, Chile central: estratigrafía, plutonismo y su relación con estructuras profundas The Cenozoic of the upper Teno River, Cordillera Principal, Central Chile: stratigraphy, plutonism and their relation with deep structures

Andean Geology, 2010
La evolución geológica cenozoica del sector central de la Cordillera Principal a ~35°S, se encuentra íntimamente relacionada con la evolución de estructuras profundas, las cuales habrían controlado, en distintas etapas de su historia, tanto la ...
