Geometry and late Mesozoic-Cenozoic evolution of the Salar de Atacama Basin (22°30′-24°30′S) in the northern Central Andes: New constraints from geophysical, geochronological and field data

Autor: César Arriagada, Katja Deckart, Juan Becerra, Andrei Maksymowicz, Fernando Martínez, Sebastián Bascuñán

Publikováno v: Tectonophysics. 759:58-78

The late Mesozoic-Cenozoic evolution of the Central Andes of northern Chile consists of a series of events related to changing conditions along the plate margin, leading to different episodes of compression and extension. A long-lasting basin which r

Structural styles of the Salar de Punta Negra Basin in the Preandean Depression (24°-25°S) of the Central Andes

Autor: Rodrigo Stumpf González, Fernando Martínez, César Arriagada, Sebastián Bascuñán

Publikováno v: Journal of South American Earth Sciences. 87:188-199

We have combined 2D seismic information with field data to interpret the structure underneath the Salar de Punta Negra Basin. The interpretation of NW-SE oriented seismic profiles along the basin shows that its structure consists of a doubly-verging

Structure of the Cordillera de la Sal: A key tectonic element for the Oligocene-Neogene evolution of the Salar de Atacama basin, Central Andes, northern Chile

Autor: Juan Becerra, Fernando Martínez, Juan Carlos Rubilar, César Arriagada, Sebastián Bascuñán

Publikováno v: Journal of South American Earth Sciences. 87:200-210

The Salar de Atacama basin is the main topographic low of the Preandean Depression of the Central Andes of northern Chile. Although numerous studies have been carried out in this area, the origin of the depression is still a matter of debate. The int

Tectonic interaction between Mesozoic to Cenozoic extensional and contractional structures in the Preandean Depression (23°–25°S): Geologic implications for the Central Andes

Autor: César Arriagada, Sebastián Bascuñán, Fernando Martínez, Cristopher López

Publikováno v: Tectonophysics. 744:333-349

A multidisciplinary study supported by field data and 2-D seismic information was conducted to understand the tectonic interactions between Mesozoic to Cenozoic extensional and contractional structures along the Preandean Depression (23°–25°S) in

Heterogeneous structure of the Northern Chile marine forearc and its implications for megathrust earthquakes

Autor: Sylvain Bonvalot, César Arraigada, Sergio Ruiz, Eduardo Contreras-Reyes, Emilio Vera, J. A. Ruiz, Sebastián Bascuñán, Andrei Maksymowicz

Publikováno v: Geophysical Journal International. 215:1080-1097

Recent studies have proposed that nucleation zones, seismic barriers and high-slip patches of megathrust earthquakes correlate with physical heterogeneities, both in the oceanic/subducting plate and in the continental wedge. We present a density-dept

Buried thrust belt front of the western Central Andes of northern Chile: Style, age, and relationship with basement heterogeneities

Autor: G. Fuentes, Fernando Martínez, S. Perroud, Sebastián Bascuñán

Publikováno v: Journal of Structural Geology. 147:104337

We present a regional-scale study combining field, seismic, and limited borehole information to analyze the structural characteristics of the thrust belt front of the western Central Andes at 21°S. This region, located in northern Chile, consists of

Multi-proxy insights into the structure and geometry of the tectonic boundary at the Cordillera de Domeyko-Salar de Atacama border: An example of the interplay between basement and foreland basins

Autor: Juan Becerra, María José Hernández, Andrei Maksymowicz, Fernando Martínez, Sebastián Bascuñán, César Arriagada

Publikováno v: Tectonophysics. 807:228818

The study of the Cordillera de Domeyko and the Salar de Atacama Basin in northern Chile has been critical to understand the generation of the Andean Cordillera and the migration of the deformation front eastwards. However, the relation between the up

Subduction zones provide direct insight into plate boundary deformation and by studying these areas we better understand tectonic processes and variability over time. We studied the structure of the offshore subduction zone system of the Pampean flat
