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 ...

WebMay 13, 2024 · They occur in extensional regimes (such as accommodation in the hanging wall of listric faults), compressional regimes as back-thrusts, and strike-slip faults. Opposing subsidiary structures are synthetic where the displacement has the same shear sense as the master fault. Antithetic and synthetic faults commonly occur in parallel arrays. Cf.
