Recurring extensional and strike-slip tectonics after the Neoproterozoic collisional events in the southern Mantiqueira province

open access: yesAnais da Academia Brasileira de Ciências, 2012
In Eastern South America, a series of fault-bounded sedimentary basins that crop out from Southern Uruguay to Southeastern Brazil were formed after the main collisional deformation of the Brasiliano Orogeny and record the tectonic events that affected ...

Interactions between Cenozoic tectonics and landscape dynamics in Londrina, Paraná, Brazil

open access: yesRevista Brasileira de Geomorfologia
The Londrina City, located in southern Brazil, is situated on the basalt of the Paraná Igneous Province (PIP), near tectonic structures such as the Guaxupé faults and the São Jerônimo-Curiúva and São Sebastião lineaments, with a history of reactivation ...

Geodynamic conditions for Cenozoic activation of tectonic structures in Southeastern Mongolia

open access: yesГеодинамика и тектонофизика, 2018
The knowledge of the neotectonic structures inSoutheastern Mongolia, that is considerably distant from the active plate boundaries, is important for determining a source of tectonic deformation and regular features of activation in the intracontinental ...

Evidence for surface uplift of the Atlas Mountains and the surrounding peripheral plateaux: Combining apatite fission-track results and geomorphic indicators in the Western Moroccan Meseta (coastal Variscan Paleozoic basement) [PDF]

open access: yes, 2010
This work represents an initial attempt to link the evolution of the topography in relation to the general tectonic framework of western Morocco. For this purpose, in a section of the Western Moroccan Meseta different tools are combined in order to ...

On the Paleostress Analysis Using Kinematic Indicators Found on an Oriented Core

open access: yesUniversal Journal of Geoscience, 2014
Paleostress analysis enables identification of stress history of a studied area. Reliable data are however necessary to get consistent results. Fault planes containing kinematic indicators have to be searched and recognized. If surface field survey is impossible, data are lacking, or deeper parts of a rock environment are being studied, boreholes can ...

Mesoproterozoic Strike-Slip Faulting within the Åland Rapakivi Batholith, Southwestern Finland

open access: yesTektonika
Paleostress inversion analysis of outcrop data from brittle fault structures within the Mesoproterozoic 1.58 Ga Åland rapakivi granite, southwestern Finland, revealed two separate strike-slip faulting stages. Stage 1 is dominated by dextral slip along E–

Morphological analysis of volcanic cones and its implication to Quaternary tectonics of the Jeju Island (South Korea)

open access: yesQuaternary Science Advances
The morphological characteristics and distribution of volcanic cones of Jeju Island in Korea could be controlled by several factors, including stress field in the substrate and subsurface fractures. Controlling fractures, however, might not be visible on

Extensional neotectonics around the bend of the Western/Central Alps: an overview [PDF]

open access: yes, 2018
The Western Alps' active tectonics is characterized by ongoing widespread extension in the highest parts of the belt and transpressive/compressive tectonics along its borders.
