Segmented types of these structures are separated by relay ramps, which are eventually breached.
One of these structures offset from the master and proceeding in the opposite direction is called "antithetic". Segmented types of these structures are separated by relay ramps, which are eventually breached. Anderson's theory of these structures assumes that only one principal stress is perpendicular to the Earth while the other two are parallel. Marker horizons and piercing points can be used to determine directions for these structures. Psuedotachylite and cataclasites often form in the core of these structures. These structures separate horsts and grabens, and they are classified based on the movement of their hanging wall in relation to their footwall. For 10 points, identify these zones of visible shear displacement that are exemplified, in the US, by the San Andreas one.
