Indicadores cinemáticos deformacionais do granito itapeti, Região de mogi das cruzes-sp
(2014-01-01)
Itapeti granitic body is located near the cities of Mogi d as Cruzes, Guararema and Santa Branca-SP. It is inserted in Precambrian metamorphic rocks with a large extent inlaid in the Taxaquara Shear Zone. Foliations, ...
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 ...
The Borborema shear zone system, NE Brazil
(Elsevier, 1995)
The Neoproterozoic evolution of the Borborema Province is characterized by the development of a continental-scale network of transcurrent shear zones. These shear zones form a kinematically consistent system over more than ...
Tectonic setting and U/Pb zircon dating of the plutonic Socorro Complex in the Transpressive Rio Paraíba do Sul Shear Belt, SE Brazil
(1996-06-01)
The Precambrian Rio Paraíba do Sul Shear Belt comprises a 200-km-wide anastomosing network of NE-SW trending ductile shear zones extending over 1000 km of the southeastern coast of Brazil. Granulitic, gneissic-migmatitic, ...

Ductile Shear Zones
(Elsevier, 2015)
Mylonite with a big delta mantled porphyroclast of K-feldspar in a matrix of quartz, mica and feldspar. Mylonite is derived from a porphyritic granite characterized by large K-feldspar phenocrysts (up to 20 cm long). ...

One kilometre-thick ultramylonite, Sierra de Quilmes, Sierras Pampeanas, NW Argentina
(Elsevier, 2015-01)
We describe a 1 km-thick ultramylonite forming the high strain base of the >3.5 km-thick El Pichao shear zone in the Sierra de Quilmes. This shear zone thrusted granulite facies migmatites onto amphibolite facies rocks ...
Paleostress Fields And 3-D Structure Of Poliphase Shear Zones In The Transition Craton-Orogenic Belt: Examples From The Neoproterozoic Of Southeastern Bahia, Brazil
(2000)
The IICSZ is a N45°-trending, 30km wide, intracratonic shear zone, extending for some 150km through the SSE portion of the Bahia State. The IICSZ is closely related to dykes and syenites of the Alkaline Igneous Suite of ...
