Tectonic evolution of an intraplate basin: the Lower Tagus Cenozoic Basin, Portugal
Basin Research, 2016AbstractThis article focuses on the reinterpretation of well, seismic reflection, magnetic, gravimetric, surface wave and geological surface data, together with the acquisition of seismic noise data to study the Lower Tagus Cenozoic Basin tectono‐sedimentary evolution.

Widespread ca. 1.4 Ga intraplate magmatism and tectonics in a growing Amazonia
GFF, 2015AbstractHigh-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.

Tectonics and magmatism of intraplate oceanic rises and the hot-spot hypothesis
Geotectonics, 2008The brief characteristics of the large intraplate rises of the Indian and Atlantic oceans—the Ninetyeast, Mascarene, Maldives, and Walvis ridges and the Kerguelen Plateau—are discussed. The formation of these, as well as many other intraplate ridges, plateaus, and islands, is usually thought to be a result of the function of long-lived stationary deep ...

Apparent stress and stress drop for intraplate earthquakes and tectonic stress in the plates
pure and applied geophysics, 1977The magnitude of shear stress in the lithosphere is bounded from below by the apparent stress and stress drop during intraplate earthquakes. Apparent stresses and stress drops for a number of mid-plate earthquakes are calculated from the earthquake magnitude, SH wave amplitude spectra, and estimates of the length of the fault zone.

Hotspots and mantle plumes: global intraplate tectonics, magmatism and ore deposits
Mineralogy and Petrology, 2004Intraplate tectono-magmatic phenomena, including the emplacement of layered intrusions, and the giant dyke swarms, anorogenic (hotspot) volcanism, oceanic plataeux, rifting processes, basin formation, and geomorphological features are discussed in the context of the mantle plume theory.

The structure and tectonics of the intraplate deformation area in the Indian Ocean
Tectonophysics, 1988Abstract Intense tectonic deformations of sediments and basement unusual for the interior of the oceanic lithosphere plates can be seen on seismic reflection profiles from the northern Central Indian Basin. 10,000-mile long CSP profiles collected by the P.P.

Classification of intracontinental (intraplate) orogeny based on tectonics and its evolution
Since last 1960’s, the plate tectonics has been played a main role for the study on the Earth’s evolution and global tectonics, but mostly focused on the global divergence and convergence, and focused on the continental margin—subduction and collision.Yu Wang, Songnan Liu, Mo Gong

Tectonics, 1996
The area occupied by the Variscan belt of central Europe forms part of Gondwana‐derived microplates (essentially Avalonia and Armorica) that, according to paleomagnetic data, juxtaposed Baltica and Laurentia from the Upper Ordovician to the Lower Devonian.
