Geomechanical paleostress inversion using fracture data

Journal of Structural Geology, 2016
Abstract We describe a fast geomechanically-based paleostress inversion technique that uses observed fracture data to constrain stress through multiple simulations. The method assumes that the local stress field around individual fractures is heterogeneous and derives the far field tectonic stress, that we also call the far field boundary conditions.

Kinematic development and paleostress analysis of the Denizli Basin (Western Turkey): implications of spatial variation of relative paleostress magnitudes and orientations

Journal of Asian Earth Sciences, 2006
Paleostress orientations and relative paleostress magnitudes (stress ratios), determined by using the reduced stress concept, are used to improve the understanding of the kinematic characteristics of the Denizli Basin. Two different dominant extension directions were determined using fault-slip data and travertine fissure orientations.

Compiling and correlating paleostress fields across Central Europe - A paleostress chart for northern Bavaria and adjacent areas

2021
<p>Detailed knowledge on the temporal and spatial distribution of faults and fractures not only reveals the geodynamic and tectonic evolution of the lithosphere. It is also of increasing importance with regard to economic, social, and environmental challenges such as nuclear waste disposal, gas storage, geothermal energy, natural hazards,

Bedding tilt test for paleostress analysis

Journal of Structural Geology, 2005
It is difficult to apply stress inversion to fault-slip data obtained from highly tilted sedimentary layers, especially in areas where criteria for fault sorting are not available at outcrops. This paper shows that a bedding tilt test similar to that used in paleomagnetism allows paleostresses to be inferred.

Paleostress reconstruction of the southeast Ukrainian Outer Carpathians

International Geology Review, 2021
The paleostress analysis of the southeast part of the Ukrainian Outer Carpathians (UOC) was carried out with the separation and stress inversion TR method (TRM).

Microfracturing, paleostress and the growth of faults

Journal of Structural Geology, 1994
Abstract We have analyzed the microfractures in samples taken near one thrust fault and five normal faults of known displacement to test the dependence of microfracture density and distribution on fault slip. We have also recorded the orientation of microfractures as a function of distance from the associated fault surface.

Orientation of Paleostress of Raplee Ridge Anticline

The Compass: Earth Science Journal of Sigma Gamma Epsilon, 2019
During the Laramide Orogeny several major folds were formed in Southern Utah, one of those being the Raplee Ridge anticline. Raplee Ridge is approximately eight miles from Mexican Hat, Utah. The San Juan River cuts through the anticline, exposing the Honaker Trail Formation’s beds of shale and limestone with chert nodules.
