Seismic-gravimetric analysis of the subducted Nazca plate 1 between 32°S and 36°S

Autor: Lujan Eckerman, Alejo Agüero, Silvana Spagnotto, Patricia Martinez, Silvina Nacif

Publikováno v: Geodesy and Geodynamics, Vol 9, Iss 1, Pp 57-66 (2018)

The study region is seismically and tectonically characterized by the angle variations in the subduction of the Nazca plate. The results obtained from earthquakes location between 32° and 36°S latitude and 67°–71°W longitude are presented in th

Vertical slab-tearing has been widely reported in modern convergent settings profoundly influencing subduction and mantle dynamics. However, evaluating a similar impact in ancient convergent settings, where oceanic plates have been subducted and the

Crustal anatomy and evolution of a subduction-related orogenic system: Insights from the Southern Central Andes (22-35°S)

Autor: Laura Giambiagi, Andrés Tassara, Andrés Echaurren, Joaquín Julve, Rodrigo Quiroga, Matías Barrionuevo, Sibiao Liu, Iñigo Echeverría, Diego Mardónez, Julieta Suriano, José Mescua, Ana C. Lossada, Silvana Spagnotto, Macarena Bertoa, Lucas Lothari

Publikováno v: Earth-Science Reviews. 232:104138

As the archetype of mountain building in subduction zones, the Central Andes has constituted an excellent example for investigating mountain-building processes for decades, but the mechanism by which orogenic growth occurs remains debated. In this st

In this work, we develop a multidisciplinary approach to investigate a geothermal system located at the volcanic arc of a subduction-related orogen and highlight the interplay between active tectonism, stress field and fluid migration. By using resul

Publikováno v: Pure and Applied Geophysics. 176:611-625

In this work we have analyzed the results of temporal geodetic variations associated with tectonic deformation on the Andean backarc in southern San Juan province, Argentina. This area is affected by the subduction of the Juan Fernández Ridge and ha

We integrate field and wellbore data to discuss the stress field in the frontal sector of the Malargüe fold-and-thrust belt (Andes of Argentina). Surface observations indicate N-S thrusts and NW to WNW and ESE strike-slip faults are active in the st
