Density heterogeneity of the Earth’s crust of the Ingul megablock of the Ukrainian Shield according to the data of three-dimensional gravity modeling

Геофизический журнал, 2015
According to the data of three-dimensional density modeling at the scale 1:200 000 the peculiarity  of the Earth’s crust structure of the Korsun-Novomirgorod pluton and Novoukrainka massif has been found as well as density distribution by depth and ...

Fault rock evolution and fluid flow in sedimentary basins [PDF]

, 1989
Structural studies have been undertaken in two extensional fault regimes associated with post-Caledonian basin-forming events in northern Scotland. A combination of detailed mapping and microstructural analysis has revealed the deformation processes and ...

Thermochronological investigation of fault zones [PDF]

, 2012
The timing of faulting episodes can be constrained by radiometric dating of fault-zone rocks. Fault-zone material suitable for dating is produced by tectonic processes, such as (1) fragmentation of host rocks, followed by grain-size reduction and ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Structural evolution and reservoir-control mechanisms of ultra-deep strike–slip fault zones in the Fuman area, Tarim Basin, China

Petroleum
The discovery of ultra-deep strike–slip fault–controlled hydrocarbon reservoirs in the central Tarim Basin has renewed interest in the structural evolution and reservoir-controlling mechanisms of intracratonic strike–slip systems.

Fault development and interaction in distributed strike-slip shear zones: an experimental approach

, 2003
Analogue model experiments using both brittle and viscous materials were performed to investigate the development and interaction of strike-slip faults in zones of distributed shear deformation. At low strain, bulk dextral shear deformation of an initial

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

, 2015
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Quantitative characterization of fault damage zones in shale reservoirs: asymmetric structures and their implications for fluid flow, a case study from the Gulong Sag, Songliao basin

Frontiers in Earth Science
Fault damage zones serve as critical conduits for fluid migration in shale reservoirs characterized by low matrix permeability. Addressing the challenges in quantitatively characterizing fault damage zones in shale, this study takes the Gulong shale in ...
