Faults strike-slip

Strike-slip faulting—occurs, when the blocks slide laterally relative to each other. 

Lallemand and Jolivet (1986) have interpreted the opening of the Japan Sea as a pull-apart basin between two right-lateral strike-slip fault zones the Yagsan-Tsushima fault to the west and the Tartary-Hidaka shear zone to the east.

The mineralized district is restricted by two main strike-slip faults of Kubanan to the east and Posht e Bdam to the west (Fig. la). The host rocks are a thick sequence of Upper Precambrian-Cambrian rhyolite, tuff, alkali granite, syenite, mafic dykes, magnetitite, dolomite, gypsum, limestone, black shale, and sandstone. The Upper Percambrian-Cambrian sequence is overlain unconformably by Mesozoic and...

Like the whole of the Classical Karst of Slovenia, the area investigated lies on the Adriatic sub-plate, a part of the African macroplate. The contact with the European continent lies about 80km to the north. During the last 2 Ma, changes in the motion of the Adriatic sub - plate have led to the establishment of several dextral strike - slip faults of Dinaric trend (i.e. southeast to northwest direction). As a reflection of its 12 km displacement and ongoing neotectonic activity, the Idria Fault is usually considered the...

Fig. 1. (a) Simplified regional map showing the position of the Zimbabwe Craton, greenstone belts, major shear zones as visible on Landsat TM images (e.g. RGB741), and orogenic belts. The shear zones may represent terrane boundaries and/or late strike-slip fault zones. Numbers refer to greenstone belt names. 

The discovery well intersected an 8 2 m net gas column in Upper Angel Formation sandstones. Three appraisal wells established major hydrocarbon reserves at the same stratigraphical horizon, with a maximum gas column of 140 m (Vincent Tilbury, 1988). A thin oil leg was discovered beneath the gas cap in all four wells, but is thickest at Angel-3 (20 m), the only well drilled south of a major ENE-WSW-oriented strike-slip fault zone that traverses the field (Ryan-Grigor Schulz-Rojahn, 1995). The gas composition in Angel Formation reservoirs consists of dominantly methane (80% by molar volume), ethane (6%), propane (3%) and heavier hydrocarbon gases (up to C7+), including minor carbon dioxide (less than 3%) (Woodside, 1971, 1972, 1990). 

The 3D seismic data show that four different sets of faults occur at reservoir level in the Angel Field area (Fig. 20). The most prominent are ENE-WSW-oriented strike-slip faults that concentrate in a zone 1 km wide south of Angel-1, Angel-2 and Angel-4. 

The fault zone traverses the width of the Angel Field. Other secondary faults include NW-SE-trending normal faults, NNW-SSE-trending strike-slip faults, and NNE-SSW-trending reverse faults. 

Rapid Carboniferous subsidence was followed by Late Carboniferous-Permian uplift which was part of the regional Late Variscan inversion event. Although a dominant N-S to NNW-SSE compres-sional stress field is recognized through NW Europe at this time (Coward, 1995), Kerr (1987) demonstrated evidence for local E-W compression in the North Antrim region. This resulted in E-W strike-slip faults and transtensional N-S reactivation of...

For this aim, we use a numerical model which is on the one hand to some degree physical, and on the other hand simple enough that it allows to perform long simulations. The basic version of the model consists of a segmented two-dimensional strike-slip fault in a three-dimensional elastic half space and is inherently discrete, because it does not arise from discretizing a continuous model. 

Faults in which the dominant displacement is horizontal movement along the trend or strike (length) of the fault are called strike-slip faults. When a large strike-slip fault is associated with plate boundaries it is called a transform fault. The San Andreas Fault in California is a well-known transform fault.
