TLDR
In this article, the authors used regional patterns of present-day tectonic stress to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity, and found that most intraplate regions are characterized by a compressional stress regime; extension is limited almost entirely to thermally uplifted regions.Abstract:
Regional patterns of present-day tectonic stress can be used to evaluate the forces acting on the lithosphere and to investigate intraplate seismicity. Most intraplate regions are characterized by a compressional stress regime; extension is limited almost entirely to thermally uplifted regions. In several plates the maximum horizontal stress is subparallel to the direction of absolute plate motion, suggesting that the forces driving the plates also dominate the stress distribution in the plate interior.read more

Plate reorganization: a cause of rapid late Neogene subsidence and sedimentation around the North Atlantic?
TL;DR: Subsidence analysis of wells in the central North Sea and Labrador-Grand Banks and the West Greenland, Scotian shelf and United States Atlantic margin shows distinct quantitative stratigraphic correlation patterns of circum North Atlantic sites as discussed by the authors.

The regional intraplate stress field in South America
TL;DR: A compilation of lithospheric stress directions for continental South America and the inferred major patterns of the regional intraplate stress field are presented in this paper, which is useful in constraining numerical models of the plate driving forces in the South American plate.

Stress perturbations associated with active faults penetrated by boreholes: Possible evidence for near-complete stress drop and a new technique for stress magnitude measurement
Colleen A. Barton,Mark D. Zoback +1 more
TL;DR: In this article, the authors use three-dimensional dislocation modeling to demonstrate that these discontinuities can be explained as the superposition of a reference stress state and a perturbation caused by movement on preexisting faults.

An overview of rock stress measurement methods
TL;DR: An overview of methods that have been used to estimate the state of stress in rock masses, with the emphasis on methods applicable to hard rocks and Scandinavia, is given in this paper.

Short-lived and discontinuous intraplate volcanism in the South Pacific: Hot spots or extensional volcanism?
TL;DR: This paper used 40 Ar/39 Ar seamount ages and Sr-Nd-Pb isotopic signatures to map out Cretaceous volcanism in the West Pacific Seamount Province (WPSP) and to characterize its evolution with respect to the currently active hot spots in the SOPITA region.

An analysis of the variation of ocean floor bathymetry and heat flow with age
Barry Parsons,John G. Sclater +1 more
TL;DR: In this paper, a simple cooling model and the plate model were proposed to account for the variation in depth and heat flow with increasing age of the ocean floor. But the results were limited to the North Pacific and North Atlantic basins.
Present-day plate motions
TL;DR: A data set comprising 110 spreading rates, 78 transform fault azimuths, and 142 earthquake slip vectors has been inverted to yield a new instantaneous plate motion model, designated Relative Motion 2 (RM2).

On the Relative Importance of the Driving Forces of Plate Motion
Donald W. Forsyth,Seiya Uyedaf +1 more
TL;DR: In this paper, the relative strength of the plausible driving forces, given the observed motions and geometries of the lithospheric plates, was analyzed. But the results indicate that the forces acting on the downgoing slab control the velocity of the oceanic plates and are an order of magnitude stronger than any other force.
