Paleostress regimes from brittle structures of the Karakoram–Kohistan Suture Zone and surrounding areas of NW Pakistan

Journal of Asian Earth Sciences, 2010
International audiencePaleostress orientations were calculated from fault populations at 24 sites along the SW-NE segment and five sites along the E-W. Yasin segment of the Karakoram-Kohistan Suture Zone in NW Pakistan They demonstrate the importance of ...

Tectonophysical Paleostress Reconstructions: Interpretation Challenges and Possible Solutions

Russian Geology and Geophysics, 2019
Abstract —Paleostress inversion may be ambiguous when several markedly different local stress states are inferred for a group of outcrops. Attempts of reconstructing regional stress regimes (compressional, extensional, or strike-slip) by selecting local principal stresses of proximal directions turn out to have poor grounds.

Magnetic fabric, strain and paleostress in the Canadian Rocky Mountains

Tectonophysics, 1983
Abstract The paper reports a detailed study of the anisotropy of magnetic susceptibility at two localities 100 km apart in the Canadian Rocky Mountains, both in the Miette Group of Precambrian sediments which was folded during the Laramide Orogeny.

Using joint interactions to estimate paleostress ratios

Journal of Structural Geology, 1988
Because they grow perpendicular to a minimum principal stress (σ3), joints are paleostress markers. Younger joints may show a systematic change in orientation as they approach older, throughgoing, joints. This change in orientation reflects a change in the stress field in which the younger joint set is growing. Analytical solutions for the stress field

Paleostress analysis from sheared dike sets

Geological Society of America Bulletin, 1989
It is a frequently reported feature of basement terranes that dikes intruded late in the deformation sequence become sheared parallel to the dike margins. It is proposed that such sets of sheets with internal fabrics produced by this shearing along their walls are structures which are dynamically analogous to reactivated faults.

Observed Paleostress Orientations and Predicted Plate-Hotspot Motions

2003
As Plate Tectonics matured, a number of workers began to consider philosophical implications of the science. Allan Cox (1973), in particular, found Thomas Kuhn’s “Structure of Scientific Revolutions”; published in the same year as Harry Hess’s “History of ocean basins — an essay in geopoetry”, to be directly applicable to the experience of earth ...

Forty years of paleostress analysis: has it attained maturity?

Journal of Structural Geology, 2019
Abstract Powerful methods of paleostress analysis from fault-slip data have been used since the 1970's, and have demonstrated their capacity for reconstructing stress fields with tectonic significance. However, in some cases, these methods have been applied to samples that do not fulfill basic requirements, or developed on the basis of unsound ...
