Cenozoic Plate Tectonic Reconstructions and Plate Boundary Processes in the Southwest Pacific [PDF]

open access: yes, 2005
The Australia-Pacific-Antarctic plate circuit has long been a weak link in global plate reconstruction models for Cenozoic time. The time period spanning chron 20 to chron 7 (43-25 Ma) is particularly problematic for global plate models because seafloor

Relation between Reopening Pressure and Tectonic Stresses for Hydraulic Fracturing Tectonic Stress Measurements.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1992
In order to establish the methodology of hydraulic fracturing tectonic stress measurements, the relation between the so-called reopening pressure of longitudinal cracks and tectonic stresses is studied. To this end, the coupled problem of fluid flow in the crack and the crack reopening behavior in an impermeable rock is analyzed based on the linear ...

Application of Linked Stress Release Model To Historical Earthquake Data: Comparison Between Two Kinds of Tectonic Seismicity [PDF]

open access: yes, 2000
The linked stress release model, incorporating a slow buildup of stress within a seismic region, its stochastic release through earthquakes and transfer between seismic regions, is applied to fit historical data from two typical kinds of seismicity ...

Tectonic significance of changes in post-subduction Pliocene-Quaternary magmatism in the south east part of the Carpathian-Pannonian Region [PDF]

open access: yes, 2010
The south-eastern part of the Carpathian–Pannonian region records the cessation of convergence between the European platform/Moesia and the Tisza–Dacia microplate.

Earthquake Predicting and Tectonic Stress Reducing Possibilities

open access: yes, 2022
Abstract Recent satellite and ground-based observations prove that during the earthquake formative period VLF/LF and ULF electromagnetic emissions are observed in seismogenic areas. The present consolidated paper describes a theoretical model of the generation of electromagnetic emissions detected during the earthquake preparation periods, a ...

Impact of differential stress on fracture due to volume increasing hydration [PDF]

open access: yesSolid Earth
The volume increase that accompanies many hydration reactions can stress and fracture the surrounding rock, a process commonly called reaction-induced fracturing.

Temporal relations between mineral deposits and global tectonic cycles [PDF]

open access: yes, 2013
Natural Environment Research Council (grant NE/J021822/1) supported this research.Mineral deposits are heterogeneously distributed in both space and time, with variations reflecting tectonic setting, evolving environmental conditions, as in the ...

Mechanism for stress abnormality and rock burst in variation zone of roof-stratum thickness

open access: yesYantu gongcheng xuebao, 2023
The roof stratum structure is one of the main factors affecting coal burst, and the coal burst is also easily induced in the variation zone of roof-stratum thickness. This phenomenon is gradually severe in deep mining areas in Inner Mongolia.

Results of long-term tectonomagnetic research in the Akademik Vernadsky station region, the West Coast of the Antarctic Peninsula

open access: yesУкраїнський антарктичний журнал, 2022
The study aims to analyze the results of long-term tectonomagnetic observations on the Antarctic tectonomagnetic polygon in the region of the Akademik Vernadsky station to investigate the current geodynamics at the West Coast of the Antarctic Peninsula ...
