Fault geometry and fluid-rock reaction: Combined controls on mineralization in the Xinli gold deposit, Jiaodong Peninsula, China

Journal of Structural Geology, 2018
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.

Geometry of faults

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.

Analogue models of extensional fault geometries

Geological Society, London, Special Publications, 1987
Summary 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.

A novel fault diagnosis procedure based on improved symplectic geometry mode decomposition and optimized SVM

, 2020
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.

Mechanical controls on fault geometry

Journal of Structural Geology, 1999
Abstract 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

Symplectic geometry mode decomposition and its application to rotating machinery compound fault diagnosis

Mechanical systems and signal processing, 2019
Various existed time-series decomposition methods, including wavelet transform, ensemble empirical mode decomposition (EEMD), local characteristic-scale decomposition (LCD), singular spectrum analysis (SSA), etc., have some defects for nonlinear system ...

The impact of fault surface 3D geometry on risking fault reactivation

2023
The 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

3D Fault Plane Geometry and Fault Scaling Studies Using Seismic Attributes

Proceedings, 2015
We have applied an advanced seismic fault attribute workflow to improve images of faults at different scales. The attribute volumes were used to study the actual geometry of fault plane in 3D in space. This fault plane assessment is independent of uncertainties imposed by traditional seismic-interpretation.

Fault geometry and architecture, an integrated study

2021
<p>Understanding fault geometry and processes of faulting are important research areas for many applications such as petroleum exploration and production; geothermal energy managements; hydrogeology; waste disposal and CO2 storage underground; earthquake seismology and geological hazard studies.

Influence of Small-scale Fault Geometry on Across-fault Fluid Flow

Proceedings, 2012
Few case studies have demonstrated the importance of small-scale fault zone complexities on across fault fluid flow and little progress has been made in modeling and implementing them in reservoir simulation models. In this study, we use a high quality 4D seismic dataset from offshore West Africa to investigate the relationship between small-scale ...
