Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

open access: yes, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

PRESENTDAY STRESS STATE OF THE SHANXI TECTONIC BELT

open access: yesГеодинамика и тектонофизика, 2015
The Shanxi tectonic belt is a historically earthquakeabundant area. For the majority of strong earthquakes in this area, the distribution of earthquake foci was controlled by the N–S oriented local structures on the tectonic belt.

End Late Paleozoic tectonic stress field in the southern edge of Junggar Basin

open access: yes, 2012
This paper presents the end Late Paleozoic tectonic stress field in the southern edge of Junggar Basin by interpreting stress-response structures (dykes, folds, faults with slickenside and conjugate joints).

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]

open access: yes, 2016
The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

Hotspots, trends, and regional focus on oil or gas exploration: A bibliometric comparative study

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper explores the research trends in global oil and gas exploration through the bibliometric analysis of 3460 articles collected from the Web of Science database on oil and gas exploration published from 2013 to 2023. The research hotspots, objects, regional distribution, methods, and evaluation methods of oil and gas exploration are analyzed and

Rupture Process of Subduction-Zone Earthquakes [PDF]

open access: yes, 1986
This review is primarily concerned with the rupture process of large subduction-zone earthquakes determined by various seismological methods, and with its interpretation in terms of an asperity model.

A perspective review of applications of the computed tomography (CT) scan imaging technique for microscopic reservoir rock characterization

open access: yesDeep Underground Science and Engineering, EarlyView.
In this review, the application of micro‐CT and medical‐CT scanning in the oil and gas industry has been thoroughly discussed. Recent improvements in DRP and modern imaging techniques in the oil and gas industry have been modeled using both experimental and simulation work.

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring
