Brittle Deformation in the Neoproterozoic Basement of Southeast Brazil: Traces of Intraplate Cenozoic Tectonics [PDF]

open access: goldGeosciences, 2021
The basement of southeast Brazil is traditionally interpreted as the result of Neoproterozoic and early Paleozoic orogenic cycles. Wide regions of the Atlantic Plateau (southeast Brazil) are characterized by rocks and tectonic structures of Precambrian ...

Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]

open access: yesJournal of Seismology, 2012
It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...

Widespread ca. 1.4 Ga intraplate magmatism and tectonics in a growing Amazonia

open access: greenGFF, 2015
AbstractHigh-quality U–Pb (Isotope Dilution-Thermal Ionisation Mass Spectrometry; ID-TIMS) baddeleyite ages were obtained for the Salto do Ceu (SC) gabbroic sill (1439 ± 4 Ma) and Nova Lacerda mafic dyke swarm (1387 ± 17 Ma) located ca. 150 km apart in the Jauru terrane (Paleo- to Mesoproterozoic) – SW Amazonia.

Intraplate deformation of Gondwana terranes and implications for the Wilson Cycle [PDF]

open access: yesScientific Reports
The Wilson Cycle, a cornerstone of plate tectonic theory, describes the cyclical evolution of ocean basins from rifting and spreading to closure via subduction and continental collision and assembly.

Tectonically assisted emplacement of oceanic intraplate volcanoes: The Bathymetrists Seamounts, central Atlantic

open access: greenGeomorphology, 2023
The origin of broad intraplate volcanic provinces has been related to deep mantle plumes or shallow lithospheric processes, e.g., underlying large fault systems. One example of an understudied intraplate volcanic province is the Bathymetrists Seamounts (BSM) in the central-eastern Atlantic, an area with dense and extended fracture zones, but the BSM ...

The intraplate Euphrates fault system-Palmyrides mountain belt junction and relationship to Arabian plate boundary tectonics

open access: diamondAnnals of Geophysics, 1995
We interpret seismic data and well logs to indicate that the Euphrates graben, intersecting orthogonally with the Palmyride mountains, is an intraplate transtensional feature that probably developed in response to plate boundary stress created by a ...

Volcanism and seismicity in the Indo-Australian seismic belt: manifestations of intraplate tectonics

open access: diamondAnnals of Geophysics, 1978
Disregarding the mid-oceanic ridges, the oceanic part of the Indo-<br />Australian Seismic Belt is the longest, seismically active zone in the<br />world-ocean. It begins west of Ceylon and runs towards Australia.

Alpine paleostress reconstruction and active faulting in Western Iberia [PDF]

open access: yesOpen Geosciences, 2010
The study of intraplate tectonics is crucial for understanding the deformation within plates, far from active plate boundaries and associated stress transmission to the plate interiors.

Mantle Sources of Recent Anatolian Intraplate Magmatism: A Regional Plume or Local Tectonic Origin? [PDF]

open access: bronzeTectonics, 2018
AbstractWe present an extensive study of rehomogenized olivine‐hosted melt inclusions, olivine phenocrysts, and chromian spinel inclusions to explore the link between geodynamic conditions and the origin and composition of Pliocene–Quaternary intraplate magmatism in Anatolia at Kula, Ceyhan‐Osmaniye, and Karacadağ. Exceptional compositional variability
