Partición de la deformación en la zona del arco volcánico de los Andes neuquinos (36-39°S) en los últimos 30 millones de años
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2002)
Evaluación geológica post-sismo del 14 de agosto del 2016: reactivación de la falla Yanque, Arequipa
(Sociedad Geológica del PerúPE, 2016)
[ENG] Colca fault system presents intense seismic activity and the last earthquake confirms it. This event was the result of Yanque fault reactivation. It was a shallow quake (hypocenter depth 8km) with 5.3 ml magnitude, ...
Características litológicas y geoquímicas mas resaltantes de los arcos magmáticos del Perú desde el Ordovícico
(Sociedad Geológica del Perú - SGPPE, 2013)
El trabajo da a conocer los resultados preliminares de los estudios de arcos y trasarcos magmáticos, y discute la relación entre las fases distensivas y comprensivas y/o inversión con el volumen de producción de rocas ...
Geochronology and geochemistry of Early Cretaceous volcanic sequences in Northwestern Peru: implications for Farallon Plate subduction
(Taylor & FrancisPE, 2022-01)
The Early Cretaceous geology of Northwestern (NW) Peru was characterized by emplacement of voluminous felsic volcanic rocks (e.g. the Oyotún Fm.), which have important implications for the understanding of Early Cretaceous ...
Contrasting Ordovician high- and low-pressure metamorphism related to a microcontinent-arc collision in the Eastern Cordillera of Perú (Tarma province)
(ElsevierNL, 2014-10)
High-pressure conditions of 11–13 kbar/500–540 °C during maximum burial were derived for garnet amphibolite in the Tapo Ultramafic Massif in the Eastern Cordillera of Peru using a PT pseudosection approach. A Sm–Nd ...
Paleoseismic evidence of the 1715 C.E earthquake on the Purgatorio Fault in Southern Peru: implications for seismic hazard in subduction zones
(ElsevierNL, 2022-07)
Active faults in the forearc of southern Peru pose a poorly understood hazard to the region. The Purgatorio Fault is a 60 km-long fault that extends between Moquegua and Tacna that has hosted several scarp-forming earthquakes ...
Paleomagnetic tracking of mountain building in the Peruvian Andes since 10 Ma
(John Wiley & SonsUS, 2003-09)
We report paleomagnetic data from 73 sites (628 samples) of upper Oligocene to Pliocene rocks from central and northern Peru. The data indicate that the Subandean Zone has not experienced vertical axis rotation since the ...
Crustal controls on light noble gas isotope variability along the Andean Volcanic Arc
(European Association of GeochemistryEU, 2021-11)
This study combines new noble gas data from fluid inclusions in minerals from Sabancaya, Ubinas, and El Misti (CVZ, Peru) and Villarica (South Chile, SVZ) with a revised noble gas compilation in the Andes, to identify ...
