Petrotrama de quartzo e feldspato ao longo da Zona de Cisalhamento de Jundiuvira, Cabreuva (SP)
(1993-12-01)
Fluid inclusions, petrofabric and microstructures studies of mylonites and cataclasites were used to establish the Itu-Jundiuvira Shear Zone (IJSZ) tectonic and metamorphic evolution. The quartz fabric indicates that prism ...
Análise de terrenos na porção setentrional da Província Borborema, NE do Brasil: integração de dados geológicos e gravimétricos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 1999-08-20)
It is presently assumed that the Borborema Province resulted from a complex collisional process associated with the convergent movement of plates, possibly involving amalgamation and accretion of microplates. This process ...
Timing of deformation in the Sarandí del Yí Shear Zone, Uruguay: implications for the amalgamation of western Gondwana during the Neoproterozoic Brasiliano-Pan-African Orogeny

U-Pb and Hf zircon (sensitive high-resolution ion microprobe -SHRIMP- and laser ablation-inductively coupled plasma-mass spectrometry -LA-ICP-MS-), Ar/Ar hornblende and muscovite, and Rb-Sr whole rock-muscovite isochron ...
Sm-Nd system in total rock open versus closed isotopic composition in zones of high deformation
(2002-12-01)
High strain shear zones of Brasiliano age, developed in Paleoproterozoic basement gneiss of the Caicó region, Borborema Province, NE Brazil, were associated with medium- to low-grade metamorphism and deformational processes ...

Synkinematic interplay between felsic dykes and host rock mylonitization: how magmatism assists the formation of ductile narrow shear zones in the Sierra Chica de Córdoba, Argentina
(Pergamon-Elsevier Science Ltd, 2021-03-09)
This study provides new insights about mechanisms of synkinematic interplay between dyking emplacement and ductile narrow shear zones formation in the Sierra Chica de Córdoba. A detailed analysis of structural, microstructural, ...
