Charon tectonics

Icarus, 2017
New Horizons images of Pluto's companion Charon show a variety of terrains that display extensional tectonic features, with relief surprising for this relatively small world. These features suggest a global extensional areal strain of order 1% early in Charon's history.

The Tectonics and Volcanism of Venus: New Modes Facilitated by Realistic Crustal Rheology and Intrusive Magmatism [PDF]

, 2023
To explain Venus' young surface age and lack of plate tectonics, Venus' tectonic regime has often been proposed to be either an episodic-lid regime with global lithospheric overturns, or an equilibrium resurfacing regime with numerous volcanic and tectonic activities.

Constraints on the active tectonics of the Friuli/NW Slovenia area from CGPS measurements and three-dimensional kinematic modeling [PDF]

, 2009
We use site velocities from continuous GPS (CGPS) observations and kinematic modeling to investigate the active tectonics of the Friuli/NW Slovenia area.

Numerical simulation of zonal disintegration of surrounding rock in the deep‐buried chamber

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 174-182, December 2022., 2022
Based on the finite difference software FLAC3D, the numerical simulation of cavern surrounding rock under different working conditions was carried out by using Bilinear Strain‐Softening Ubiquitous‐Joint Model (Subi). The effects of buried depth, cohesion and internal friction angle of surrounding rock on the discontinuous deformation are analyzed, and ...

Hydrogeological feasibility of mine water deep geological storage in Baotashan coarse sandstone: A case study in Ordos Basin

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022
We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Geological archive of the onset of plate tectonics

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018
Plate tectonics, involving a globally linked system of lateral motion of rigid surface plates, is a characteristic feature of our planet, but estimates of how long it has been the modus operandi of lithospheric formation and interactions range from the ...

Coal rock image recognition method based on improved CLBP and receptive field theory

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 165-173, December 2022., 2022
In view of the evident differences between coal and rock in visual attributes such as color, gloss, and texture, the complete local binary pattern (CLBP) image feature descriptor is introduced for coal and rock image recognition, and the original algorithm oversimplifies local texture features by ignoring imaging information from higher‐order pixels ...
