Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina
(Elsevier Science, 2017-03)
The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without ...
Subduction zone fluids and arc magmas conducted by lithospheric deformed regions beneath the central Andes
(Nature, 2021)
Dehydration of the oceanic subducting slab promotes the formation of magmatic arcs, intra-slab intermediate-depth seismicity, and hydration of the overlying mantle wedge. However, the complex permeability structure of the ...

Estrutura crustal da Bacia do Recôncavo-Tucano com inversão simultânea de dados sismológicos
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2021-07-30)
The stresses that led to the opening of the South Atlantic were responsible for
intracontinental extensions and, consequently, for the formation of a number of aborted
rifts in Northeastern Brazil. The extension began in ...
Crustal and upper mantle shear wave velocity structure and radial anisotropy beneath the Colombian Andes inferred from ambient noise and surface wave tomography
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2018-08-29)
The objective of this work is to investigate how subduction-related processes in NW
South America deform and alter the composition of the overriding plate, as well as the
relationship between crustal fluids and active/inactive ...
Rebote elástico de la corteza superior debido a deflexión durante desglaciación: un mecanismo de primer orden en la descompresión y activación de sistemas volcánicos superficiales = Elastic rebound of the upper crust due flexural unbending during deglaciation: a first order mechanism in decompression and activation of shallow volcanics systems.
(Universidad de Concepción.Facultad de Ciencias QuímicasDepartamento de Ciencias de la Tierra., 2019)
La descompresión inducida por grandes desglaciaciones sobre sistemas volcánicos son comúnmente
estudiadas utilizando modelos de cargas superficiales sobre la corteza terrestre, representándola como
un semi-espacio elástico ...
New geochronological and isotope data for the Las Chacras – Potrerillos and Renca batholiths: A contribution to the Middle-Upper Devonian magmatism in the pre-Andean foreland (Sierras Pampeanas, Argentina), SW Gondwana
(Pergamon-Elsevier Science Ltd, 2019-08)
The Las Chacras-Potrerillos together with the Renca batholith (Sierras de San Luis) are the largest Devonian igneous bodies in the Sierras Pampeanas after the Achala batholith (Sierra de Córdoba), all emplaced in the ...
