Faulted anticline.

An upward fold is called an anticline, while a downward fold is called a syncline. In many areas it’s common to find a series of anticlines and synclines (as in Figure 12.5), although some sequences of rocks are folded into a single anticline or syncline. It is located in northwestern Jiaoshiba faulted anticline (Fig. 2 a). It strikes in NE direction, with an extending length of 20.8 km and smaller fault displacement (50–200 m). Its fault plane occurrence is also gentle. 2.1.3. The Shimen fault. It is situated in southeastern Jiaoshiba faulted anticline, and is composed of two echelon faults.Fault-plane sections used with structure maps give a three-dimensional view of migration and trapping, and they illustrate the interplay of three critical parameters: (1) closure style, i.e., unfaulted anticline, faulted anticline, or nose, (2) cross-fault geometry, i.e., the throw and change of throw along a fault, and (3) stratigraphic ...Aug 31, 2019 · The backlimb of Karun anticline is faulted and created a pop-up structure in all seismic profiles except for the A–A′ profile (Figs. 4a, 6a, b, 9a, 10a, 11a). These characteristics cause a distinction between type II and III from type I of the faulted-detachment fold. Unexchanged or unsurrendered stocks are those shares that should have changed hands but have not.

A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements …
