Reconstruction of Tectonic Stresses in Central Sakhalin

open access: yesRussian Journal of Pacific Geology, 2023
The article presents the reconstruction of the tectonic stress field of the central part Sakhalin Island, obtained as a result of field tectonophysical studies in 2020–2022. The measurements made it possible to determine the predominant orientation of the main slickensides systems with different kinematics.

Experimental study on the deformation behaviour, energy evolution law and failure mechanism of tectonic coal subjected to cyclic loads

open access: yesInternational Journal of Mining Science and Technology, 2022
Compared to intact coal, tectonic coal exhibits unique characteristics. The deformation behaviours under cyclic loading with different confining pressures and loading rates are monitored by MTS815 test system, and the mechanical and energy properties are

Main controlling factors of natural fractures in tight reservoirs of the lucaogou formation in the jimsar sag, Xinjiang, China

open access: yesFrontiers in Earth Science, 2023
Natural fractures act as critical flow channels and reservoir space in the Lucaogou Formation tight reservoir of the Jimsar Sag. It is essential to identify the main controlling factors of natural fractures in order to achieve efficient development of ...

The coulomb stress changes for correlation analysis of tectonic earthquake activity and volcanic of the 2001–2010 Merapi eruption based on focal mechanism data

open access: yesKuwait Journal of Science, 2023
The incident of increased seismic activity of the Merapi volcano was initiated by several tectonic earthquake phenomena. Analysis of the mechanism of tectonic earthquakes can be studied based on the combination of static stress on the rock.

Present-day stress orientations and tectonic provinces of the NW Borneo collisional margin [PDF]

open access: yes, 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

Geomorphological insight into changing tectonic regime, Pasinler Basin, Turkey [PDF]

open access: yes, 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.

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]

open access: yes, 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]

open access: yes, 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.

Ionic Liquid Electrolytes for Extreme Temperature Conditions: Challenges and Perspective

open access: yesAngewandte Chemie, EarlyView.
Ionic liquids (ILs) have gained great attention as safe electrolyte components in recent years. This review elucidates the temperature effects on IL‐based electrolytes from molecular configurations, physicochemical properties, and interfacial chemistry, raises the challenges and design strategies operating at low‐ and HT, providing valuable guidance ...

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]

open access: yes, 2011
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.
