El Morro caldera (33° 10′ S, 66° 24′ W), San Luis, Argentina: An exceptional case of fossil pre-collapse updoming
(Elsevier Science, 2017-03)
Volcanism at Sierra del Morro represents the final stages of the flat-slab related magmatism in the easternmost San Luis Neogene Volcanic Belt. This ~80 km-long NW-WNW-trending belt tracks the episodic inland migration of ...
Neogene Tiporco Volcanic Complex, San Luis, Argentina: An explosive event in a regional transpressive - local transtensive setting in the pampean flat slab
(Pergamon-Elsevier Science Ltd, 2017-07)
The Neogene Tiporco Volcanic Complex (TVC) is located in the Sierras Pampeanas of San Luis, Argentina, at the southeast of the Pampean flat-slab segment. Based on the comprehensive study of lithofacies and structures, the ...
Polymetallic (Pb-Zn-Cu-Ag ± Au) vein-type deposits in brittle-ductile transtensional shear zones, Eastern Sierras Pampeanas (Argentina): Age constraints and significance for the Late Paleozoic tectonic evolution and metallogenesis
(Elsevier Science, 2017-10)
This paper discusses new structural, kinematic and geochronological data from polymetallic (Pb-Zn-Cu-Ag ± Au) vein-type deposits hosted in the metamorphic basement of the southern Sierras de Córdoba. A Carboniferous age ...
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, ...
Estilo estrutural e contexto tectonoestratigráfico do Grupo Ubajara no NW do Ceará
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2018-09-03)
The Ubajara Group is a neoproterozoic (of ediacaran age) low grade
metassedimentary unit (ediacaran) that occurs adjacent to the TransbrasilianoKandi
Lineament, in NW Ceará. This lineament corresponds to a NE-trending
dextral ...

Litoestratigrafia e deformação cenzóica na região de Icapuí, Ceará, e implicações para a estruturação de campos de petróleo na borda ocidental da bacia Potiguar(NE do Brasil)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2003-02-14)
This thesis deals with the sedimentological/stratigraphic and structural evolution of the sedimentary rocks that occur in the NW continental border of the Potiguar Basin. These rocks are well exposed along coastal cliffs ...
