Architecture, Kinematics, and Tectonic Evolution of the Principal Cordillera of the Andes in Central Chile (∼33.5°S): Insights From Detrital Zircon U‐Pb Geochronology and Seismotectonics Implications

Tectonics, 2021
AbstractWe assess the role of inherited structures on the Meso‐Cenozoic tectonic evolution of the main Andean Cordillera in central Chile (33°30′S‐34°S). Based on extensive field mapping, U‐Pb geochronology and palinspastic restorations along the Yeso and Volcán river valleys, we propose a tectono‐stratigraphic model for the evolution of a hybrid fold ...

The Mercedario rift system in the principal Cordillera of Argentina and Chile (32° SL)

Journal of South American Earth Sciences, 1999
Abstract Recent studies carried out in the High Andes of central-western Argentina in the provinces of San Juan and Mendoza have established its stratigraphic and structural evolution. This paper presents new data on the Triassic–Early Jurassic rift system, the depositional sequences, and a synthesis of the tectonic evolution of the region, along ...

A New Tectonic Model for the Contact Relationships of Mesozoic and Cenozoic Domains in the Principal Cordillera, Central Chile (33°–34°S)

Tectonics
Abstract The origin of the contact between Cenozoic rocks of the Western Principal Cordillera (WPC) and Mesozoic rocks of the Eastern Principal Cordillera (EPC) in the Chilean Andes at 33°–34°S has been debated for several years. Most authors interpret this boundary as a regional‐scale inverted fault that, during the early Miocene ...

Late Paleozoic to Early Jurassic tectonic development of the high Andean Principal Cordillera, El Indio Region, Chile (29–30°S)

Journal of South American Earth Sciences, 1999
Abstract Regional mapping (1:50,000) and U-Pb and K-Ar geochronology in the El Indio region refines the knowledge of the distribution, lithostratigraphy, and age of the sedimentary, volcanic, and intrusive rocks that comprise the regionally extensive Pastos Blancos Group which is equivalent to the Choiyoi Group of the Argentine Frontal Cordillera ...
