The intraplate character of supercontinent tectonics

Gondwana Research, 2013
Abstract For several decades geoscientists have recognised intraplate tectonic activity far from plate margins, both from modern and ancient examples. This apparent disconnect with the drivers of plate tectonics does not necessarily imply unconnected processes, but rather an uncertainty in understanding exactly how these systems operate.

Three-level Tectonic Model for Intraplate Earthquakes

Earth Science Frontiers, 2009
Abstract Earthquake is a process concerning the long-term accumulation and abrupt release of energy in nature. On the basis of the analysis of the characteristics of intraplate earthquake, we present a three-level tectonic model for intraplate earthquake.

Orogenic zones in central Australia: intraplate tectonics?

Nature, 1974
THE plate tectonics model1,2 has been successful in explaining the orogenic features of the ocean basins and continents associated with the dispersal of Pangaea in post-Triassic time. Dewey and Bird3 extended these concepts, suggesting that there is a unique relationship between orogenesis and plate-margin tectonism, and various authors have ...

Recurrent Intraplate Tectonism in the New Madrid Seismic Zone

Science, 1980
For the first time, New Madrid seismicity can be linked to specific structural features that have been reactivated through geologic time. Extensive seismic reflection profiling reveals major faults coincident with the main earthquake trends in the area and with structural deformation apparently caused by repeated episodes of igneous activity.

Late Cretaceous-Cenozoic intraplate extension and tectonic transitions in eastern China: Implications for intraplate geodynamic origin

Marine and Petroleum Geology, 2020
Abstract The geodynamic origin of intraplate extension remains poorly understood. For the case of the Late Cretaceous-Cenozoic intraplate extension in eastern China, its driving mechanism remains highly controversial due to the absence of a comprehensive understanding of significant tectonic transitions. This study uses the well-documented Cretaceous

Plate tectonic models for Indian Ocean “intraplate” deformation

Tectonophysics, 1986
Abstract The equatorial region of the conventionally defined Indo-Australian plate has long been recognized as containing a type example of intense “intraplate” deformation. We trace the development of tectonic models for the area to illustrate techniques for the analysis of such deformation.

A theory of intraplate tectonics

Journal of Geophysical Research: Solid Earth, 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 horizontal displacement of deformable plate boundaries. It is based on simple assumptions that link

Geomorphic imprint of dynamic topography and intraplate tectonism in central Australia

2020
<p>The mantle convection accompanying plate motion causes vertical movements of up to a few hundred metres at Earth’s surface over wavelengths of 10<sup>2</sup>–10<sup>3</sup> km.

Intraplate seismicity of antarctica and tectonic implications

Earth and Planetary Science Letters, 1981
Abstract We present a comprehensive study of the seismicity of the Antarctic plate for the period 1925–1980. The total seismic energy released during this period in the interior of the plate, 3.2 × 1022 ergs, is compared to figures for the African plate, of similar kinematics and size, and to the neighboring Nazca plate.

Intraplate stress as an indicator of plate tectonic driving forces

Journal of Geophysical Research, 1976
To test driving force models for plate tectonics, the global intraplate stress fields predicted by various force systems are compared with the long-wavelength features of the observed stress field as determined by midplate earthquake mechanisms, in situ measurements, and stress-induced geologic structures.
