Synthetic vs antithetic fault

Synthetic and antithetic faults. Synthetic and antithetic are terms used to describe minor faults associated with a major fault. Synthetic faults dip in the same direction as the major fault while the antithetic faults dip in the opposite direction. These faults may be accompanied by rollover anticlines (e.g. the Niger Delta … See more In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result … See more Slip is defined as the relative movement of geological features present on either side of a fault plane. A fault's sense of slip is defined as the … See more Faults are mainly classified in terms of the angle that the fault plane makes with the earth's surface, known as the dip, and the direction of slip along the fault plane. Based on the direction of slip, faults can be categorized as: • strike … See more In geotechnical engineering, a fault often forms a discontinuity that may have a large influence on the mechanical behavior (strength, … See more Owing to friction and the rigidity of the constituent rocks, the two sides of a fault cannot always glide or flow past each other easily, and so occasionally all movement stops. … See more The two sides of a non-vertical fault are known as the hanging wall and footwall. The hanging wall occurs above the fault plane and the … See more All faults have a measurable thickness, made up of deformed rock characteristic of the level in the crust where the faulting happened, of the … See more WebJun 1, 2005 · The slopes of antithetic sub-populations are higher than those of synthetic sub-populations from the same area and the difference in slope correlates with the polarity of the fault system, i.e ...

WebFeb 1, 2015 · The folds have wavelengths from 50 to 400 m and lengths in excess of 17 km. Swarms of synthetic and antithetic normal faults within the folds accommodate most of the vertical displacement. Synthetic faults have throws of more than 80 m, while vertical separation on antithetic faults is mostly between 5 m and 20 m and never exceeds 30 m.

WebR-shears are synthetic fractures, forming at acute angles of around 15° to the main fault. Due to their orientation, there is a component of tension across these fractures.

WebThe hanging wall experiences flexural bending, which creates extension, which in turn creates normal faults. Two families of hanging-wall faults develop in accordance with Coulomb's Law: synthetic (same sense of dip as the controlling fault) and antithetic (opposite sense). They intersect, often creating very complex fault patterns.

WebLess commonly, antithetic Riedel shears, or R'-shears, are also developed, at about 75° to the fault plane. These have a sense of shear opposite to that of the main fault. The synthetic and antithetic shears form a conjugate set, and therefore can be used to indicate the orientation of the stress axes when they formed. Figure 10.
