Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]
, 2010 Extent: 15p.Borehole failure observed on image and dipmeter logs from 55 petroleum wells across the NW Borneo collisional margin were used to determine maximum horizontal stress (σH) orientations; combined with seismic and outcrop data, they define seven

Tectonic stress: Models and magnitudes [PDF]
Journal of Geophysical Research: Solid Earth, 1980 The combination of plate tectonic models of intraplate stress and observations of the directions of principal midplate stresses provides two types of constraints on the magnitude of deviatoric stress in the lithosphere. First, the fit of global tectonic stress models to observations can constrain stress magnitudes if the magnitude of one of the ...

Geomorphological insight into changing tectonic regime, Pasinler Basin, Turkey [PDF]
, 2008 The Pasinler Basin, in the East Anatolian Contractional Province, features a suite of geomorphological zones, visible in the field, air photographs and Landsat and SRTM DEM imagery. These zones reflect past and current tectonically influenced processes.

Analysis of the Coal and Gas Outburst Mechanism from the Perspective of Tectonic Movement
Geofluids, 2021 Coal and gas outburst is the extreme instability caused by stress, gas, and coal. In this review article, dominant factors and inducing factors of outburst were summarized; geologic features of typical outburst cases and the effects of tectonic movement ...

Observation of local tectonic movements by a quartz-tube extensometer in the Sopronbánfalva Geodynamic Observatory, in Hungary–Validation of extensometric data by tidal analysis and simultaneous radon concentration measurements [PDF]
, 2012 In 1990 a quartz tube extensometer was installed in the Sopronbánfalva Geodynamic Observatory (SGO) of the Geodetic and Geophysical Research Institute of the Hungarian Academy of Sciences. On the basis of the 20 year data series, an average strain rate

Tectonic discrimination diagrams revisited [PDF]
, 2006 The decision boundaries of most tectonic discrimination diagrams are drawn by eye. Discriminant analysis is a statistically more rigorous way to determine the tectonic affinity of oceanic basalts based on their bulk-rock chemistry.
