Preserved extensional structures in an inverted Cretaceous rift basin, northwestern Argentina: Outcrop examples and implications for fault reactivation
(American Geophysical Union, 2008-02-14)
During the Cretaceous-Eocene interval a system of intracontinental rift basins, the Salta group rift, evolved in northwestern Argentina. Individual segments of the rift later suffered different degrees of inversion during ...
Characterization of the sedimentary deposits of cÁssia and its relationship with the cÁssia fault zone, southwest of minas geraisCaracterização dos depósitos sedimentares de cássia e sua relação com a zona de falha de cássia, sudoeste de minas gerais
(2019-01-01)
The sedimentary deposits of the Cássia region in southwestern Minas Gerais are known and intensely exploited as raw material for red ceramics since the 1930s. However, such geological materials have been poorly studied, ...
Análise da reativação de falhas normais através da modelagem física com o uso do particle image velocimetry
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2016-09-02)
Analog modeling has been used since the XIX century to simulate geological structures in order to understand the mechanisms that control their geometry and kinematics. The use of this tool in the oil industry, to help ...
Thermotectonic and fault dynamic analysis of Precambrian basement and tectonic constraints with the Parana basin
(Elsevier B.V., 2005-12-01)
The Precambrian crystalline basement of southeast Brazil is affected by many Phanerozoic reactivations of shear zones that developed during the end of the Neoproterozoic in the Brasiliano orogeny. These reactivations with ...
Selective reactivation of inherited fault zones driven by stress field changes: Insights from structural and paleostress analysis of the Pocuro Fault Zone, Southern Central Andes (32.8 degrees S)
(PERGAMON-ELSEVIER SCIENCE LTD, 2022)
This study aims to explain the selective reactivation of normal faults during the Andean orogeny at the Southern Central Andes western flank. We conducted a structural mapping and paleostress field reconstruction in the ...
Reactivation, inversion and basement faulting and thrusting in the Sierras Pampeanas of Córdoba (Argentina) during Andean flat-slab deformation
(Cambridge University Press, 2016-06)
The Sierras Pampeanas of Córdoba are the easternmost uplifted blocks caused by Andean foreland deformation, over 700 km from the Chile trench. This deformation started at c. 340 Ma through basement faults, thrusts and ...
Reativação de falhas: o caso da Zona de Falha de Cássia/MG
(Universidade Estadual Paulista (Unesp), 2018-01-11)
A Zona de Falha de Cássia corresponde a uma zona de falha transcorrente sinistral oblíqua orientada segundo a direção geral NNW-SSE. A estrutura se desenvolveu em decorrência de movimentações tardias do Cinturão de ...
The role of interplate locking on the seismic reactivation of upper plate faults on the subduction margin of northern Chile
(Nature, 2021)
Quaternary deformation in the northern Chile forearc is controlled by trench parallel shortening along reactivated Mesozoic faults. Dextral strikes-slip is expressed in NW-SE striking faults of the Atacama Fault System, ...
Episodic out of sequence deformation promoted by Cenozoic fault reactivation in NW Argentina
(Elsevier Science, 2020-02-05)
The Central Andes are the product of contractional deformation related to subduction of the Nazca plate beneath the South American continent. In this geodynamic setting, thrust belt propagation in the Central Andean ...
Tectonics, magmatism and paleo-fluid distribution in a strike-slip setting: Insights from the northern termination of the Liquiñe–Ofqui fault System, Chile
(Elsevier, 2016)
This study addresses the interplay between strain/stress fields and paleo-fluid migration in the Southern Andean Volcanic Zone (SVZ). The SVZ coexists with the margin-parallel Liquine-Ofqui Fault System (LOFS) and with ...
