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

, 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 ...

Intracontinental deformation in southern Africa during the late Cretaceous [PDF]

, 2014
Intracontinental deformation accommodated along major lithospheric scale shear zone systems and within associated extensional basins has been well documented within West, Central and East Africa during the Late Cretaceous.

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

Annals 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.

DataSheet1_On the Origin of Orphan Tremors and Intraplate Seismicity in Western Africa.docx

, 2021
On September 5–7, 2018, a series of tremors were reported in Nigeria’s capital city, Abuja. These events followed a growing list of tremors felt in the stable intraplate region, where earthquakes are not expected. Here, we review available seismological,

A theory of intraplate tectonics

, 1998
The theory of plate tectonics assumes a rigid behavior of tectonic plates and therefore fails to account for observed intraplate deformation. A new theory of intraplate tectonics is developed to calculate the first‐order intraplate deformation induced by

PALEOPROTEROZOIC TECTONICS AND EVOLUTIONARY MODEL OF THE ONEGA SYNCLINORIUM

Геодинамика и тектонофизика, 2023
Consideration is being given to the Onega Paleoproterozoic structure (Onega synclinorium, OS) as a tectonotype of intraplate negative structures, which experience intermittent subsidence over a long period of time.

Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

Terra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

Seismicity and regional tectonics of the Estremadura, Southwestern Portugal [PDF]

, 1989
The RESTE Project was an integrated geophysical-geological study of the Estremadura, southwestern Portugal. The core of the programme consisted of the acquisition and analysis of microearthquake data.

SICILIAN JURASSIC PHYSIOGRAPHY AND GEOLOGIC REALMS (ITALY)

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Two tectono-sedimentary domains, which were deformed during the Neogene and evolved into two large structural sectors, characterize the Sicilian Jurassic: the Maghrebides and Peloritani.
