Techniques, problems and uses of mega-geomorphological mapping [PDF]

open access: yes
A plea for a program of global geomorphological mapping based on remote sensing data is presented. It is argued that the program is a necessary step in bringing together the rapidly evolving concepts of plate tectonics with the science of geomorphology ...

Digital reconstruction of three‐dimensional contours and its application to microstructural evaluation of postblast rock fissure surfaces

open access: yesDeep Underground Science and Engineering, EarlyView.
In order to study the change rule of the fracture surface morphology after blasting, based on the improved cube covering method and the 3D contour digital reconstruction model, a quantitative microstructure characterization method combining the roughness evaluation index and the 3D fractal dimension is proposed, which is applied and validated in the ...

CHARACTERISTICS OF SELF‐SIMILARITY OF SEISMICITY AND THE FAULT NETWORK OF THE SIKHOTE ALIN OROGENIC BELT AND THE ADJACENT AREAS

open access: yesГеодинамика и тектонофизика, 2019
We performed a comprehensive analysis of the characteristics of self‐similarity of seismicity and the fault network within the Sikhote Alin orogenic belt and the adjacent areas.

Secular cooling of Earth as a source of intraplate stress [PDF]

open access: yes
The once popular idea that changes in planetary volume play an important role in terrestrial orogeny and tectonics was generally discarded with the acceptance of plate tectonics.

Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin

open access: yesDeep Underground Science and Engineering, EarlyView.
Potential exploration target stratum of 10 000‐m ultradeep dolomite in Sichuan Basin and Tarim Basin, China. Abstract The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.

Note on: "Inevitability of Plate Tectonics on Super-Earths" by Valencia, O Connell and Sasselov, arXiv preprint 0710.0699 [PDF]

open access: yesarXiv, 2008
Valencia et al. recently claimed that the mass of a Super-Earth (SE) is a sole factor in determining whether a SE is tectonically active or not. However, mass resolving astrometry is unable to discern between a SE and its moons if any. The fact that no exomoons have been discovered yet is rather a matter of instrumentation imperfection at the present ...

Indosinian tectonics in Vietnam

open access: yesComptes Rendus. Géoscience, 2008
Abstract In Vietnam, the Triassic Indosinian collision affected coevally the Truong Son belt and the Kontum Massif,which were not independent tectonic units, but parts of the same Gondwana-derived Indochina continental block. This thermotectonic event took place synchronously throughout Vietnam, during the Lower Triassic 250–240-Ma time interval, as ...

In situ loading of a pore network model for quantitative characterization and visualization of gas seepage in coal rocks

open access: yesDeep Underground Science and Engineering, EarlyView.
Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...

An analytical solution of direction evolution of crack growth during progressive failure in brittle rocks

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel analytical method is proposed to evaluate the shear stress effect on the progressive compressive failure and microcrack growth direction in brittle rocks. The shear stress effect on the wing crack growth direction during the progressive compressive failure is determined. The initial crack angle effect on the y‐direction peak stress and the wing
