Modelling of fault-related sedimentary geometries
55th EAEG Meeting, 1993Modelling of fault-related sedimentary geometries bas been carried out with the principal objective of understanding and predicting hangingwall traps. The models are consistent with a number of Palaeozoic, Mesozoic and Cenozoic examples from a range of basins throughout Northwest Europe. These basins include the Celtic Sea, Porcupine, Central Irish Sea,

Damage zone geometry around fault tips
Journal of Structural Geology, 1995Damage zones are described around small scale normal, strike-slip, and reverse faults cutting horizontally-bedded carbonates, shales and siltstones in the Bristol Channel basin, U.K. Two different types of brittle damage zone have been recognized: (a) fractures branching directly from the fault tip; and (b) fractures forming an en echelon array, which ...

Determining Fault Geometries From Surface Displacements
Pure and Applied Geophysics, 2017We introduce a new algorithm for determining the geometry of active parts of faults. This algorithm uses surface measurements of displacement fields and local modeling of the Earth’s crust as a half-space elastic medium. The numerical method relies on iterations alternating non-linear steps for recovering the geometry and linear steps for ...

Geological Society of America Bulletin, 1909
Introduction Two years ago Mr F. L. Ransome called attention to the confusion existing in the nomenclature of faults and noted that in the case of diagonal faults it is frequently impossible to say whether we are dealing with a normal or a reversed fault, or to determine whether a line at right angles to the fault-plane has been shortened or lengthened.

The structures and fluid-rock reaction in the Xinli gold deposit, Jiaodong Peninsula, were investigated to further understand their combined controls on the development of permeability associated with ore-forming fluid migration.

Analogue models of extensional fault geometries
Geological Society, London, Special Publications, 1987Summary The progressive development of extensional fault geometries in a sedimentary cover sequence above a rigid or deforming basement has been experimentally investigated using analogue models. Quartz sand (700 μm) was used as a modelling material.

Mechanical controls on fault geometry
Journal of Structural Geology, 1999Abstract Faults inevitably become non-planar because of how they grow and how they are affected during slip by mechanical heterogeneities inherent in the earth. Some faults acquire a non-planar geometry because of non-uniform tectonic deformation or because they grow by the linkage of originally discontinuous structures. However, even faults that are

A novel fault diagnosis procedure based on improved symplectic geometry mode decomposition (SGMD) and optimized SVM is presented. In the proposed procedure, a vibration signal is firstly decomposed by SGMD into a set of components.

The impact of fault surface 3D geometry on risking fault reactivation
2023The reactivation of faults can occur when the effective stresses acting on them are perturbed. In some cases man-made changes in effective stress can result in fault reactivation that can have enormous impacts including loss of integrity of underground storage facilities. Current practical methods for making this assessment are generally based on shear
