Contemporary tectonic stress field in China [PDF]
Earthquake Science, 2010 The contemporary tectonic stress field in China is obtained on the basis of Chinese stress field database and Harvard CMT catalogue. Result of the inverted tectonic stresses shows that the maximum principal stress axis strikes nearly north-south direction in the west part of Tibet plateau, ENE direction in North China.

Tectonic Stress Fields and Karst
2014Many natural causes exist controlling the formation of fractures. The rock properties relating to the brittleness is one of the most important of them for the variations in natural fracture density. These properties may vary from regional to local scale; they may vary significantly within the rock formations and between formations.

Tectonic stress in the Earth’s crust: advances in the World Stress Map project
Geological Society, London, Special Publications, 2003Abstract Tectonic stress is one of the fundamental data sets in Earth sciences comparable with topography, gravity, heat flow and others. The importance of stress observations for both academic research (e.g. geodynamics, plate tectonics) and applied sciences (e.g.

The sources of lithospheric tectonic stresses
Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1991Abstract The stresses associated with large-scale tectonic deformation have three possible origins: (1) plate-boundary forces counterbalanced by viscous drag beneath the plates; (2) density heterogeneities situated within the plates (say at depths shallower than 200 km); (3) mass heterogeneities in the deep mantle.

Tectonic Stress Reconstruction Based on Structural Features in Tectonic Superposition Areas
Mining, Metallurgy & Exploration, 2020Tectonic stress is an important parameter for understanding the dynamics of underground engineering and for the exploitation of coalbed methane. Multiple-period structural features usually have complex spatial relationships in tectonic superposition areas, which provides evidence for identification of the sequence of the tectonic stress period ...

Seismic activation of tectonic stresses by mining
Journal of Seismology, 2013Hard coal mining in the area of the Bytom Syncline (Upper Silesia Coal Basin, Poland) has been associated with the occurrence of high-energy seismic events (up to 109 J; local magnitude up to 4.0), which have been recorded by the local mining seismological network and regional seismological network. It has been noticed that the strongest seismic events

Earthquake Stress Drops, Ambient Tectonic Stresses and Stresses That Drive Plate Motions
pure and applied geophysics, 1977A variety of geophysical observations suggests that the upper portion of the lithosphere, herein referred to as the elastic plate, has long-term material properties and frictional strength significantly greater than the lower lithosphere. If the average frictional stress along the non-ridge margin of the elastic plate is of the order of a kilobar, as ...

Tectonic stress in the southwestern Arabian shield
Engineering Geology, 1986Abstract Studies of dam sites in the southwestern region of Saudi Arabia gave the opportunity to undertake an in-depth study of the old basement of the Arabian shield. By comparing the results obtained at all scales (seismicity, fracturing of the shield, data on overall tectonics and in-situ measurements) it has been possible to formulate an ...

Stress measurements and tectonic implications for Fennoscandia
Tectonophysics, 1991Abstract The main results from the Fennoscandian Rock Stress Data Base (FRSDB) are presented. Rock stress data from Sweden are now being selected to enter the data base of the World Stress Map Project of the International Lithosphere Programme. It is suggested that ridge push from the Mid-Atlantic Ridge is the major stress-generating mechanism.

Tectonic stress field in the Indian subcontinent
Journal of Geophysical Research: Solid Earth, 1992A map of maximum horizontal compressive stress orientation in the Indian subcontinent has been prepared using orientations derived from three different stress indicators: borehole elongation breakouts, in situ hydraulic fracturing measurements, and earthquake focal mechanisms. Most part of the subcontinent appears to be characterized by a compressional
