Control of Shear-Zone-Induced Pressure Fluctuations on Gold Endowment: The Giant El Callao District, Guiana Shield, Venezuela
(MDPI AG, 2018)
The El Callao district, with a total endowment of more than 2000 t Au, is considered to be the
most prolific gold resource in Venezuela. Mineralization is hosted by a vein system that is genetically
associated with the ...
Dating recurrent shear zone activity and the transition from ductile to brittle deformation: white mica geochronology applied to the neoproterozoic Don Feliciano Belt in South Brazil
(Pergamon-Elsevier Science Ltd, 2020-09-22)
Argon geochronology of white mica has a good potential of recording recurrent dynamic recrystallization in shear zones in the transition from ductile to brittle deformation, as temperature ranges for mineral crystallization ...
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 ...
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 ...
Structure and tectonic significance of high-and low-temperature deformation along the lateral escape-related guaçuí and batatal shear zones, Southern Araçuaí Orogen (Southeastern Brazil)
(2020-10-01)
The Guacuí and Batatal lineaments in the southern region of the state of Es-pírito Santo (southeastern Brazil) can be traced from satellite images for tens of kilometers. They are considered shear zones associated to the ...
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, ...
Tectonica do Complexo Varginha na regiao de Sao Joao da Boa Vista (SP)
(1990-12-01)
Migmatites, high-grade gneisses and granitoids represent the most important Precambrian rocks of Sao Joao da Boa Vista region. Structures are interpreted as due to low-angle oblique non-coaxial ductile shear, developed ...
