Anticlines

The Grandview-Phantom Monocline in the Grand Canyon, Arizona. Monocline at Colorado National Monument. Monocline formed at tip of small thrust fault, Brims Ness, Caithness, Scotland. A monocline (or, rarely, a monoform) is a step-like fold in rock strata consisting of a zone of steeper dip within an otherwise horizontal or gently dipping sequence.

Created up folded ridges (anticlines) and down folded valleys (synclines) aligned parallel to the coast. Sea level rise at the end of the Devensian Glacial overtopped the low points of the anticlines and the sea flooded synclines. This produces lines of narrow islands parallel to the coast formed by projecting sections of anticlines.Around the margins of the Bighorn Basin are numerous anticlines, many of which are located on the hanging walls of the Rio, Oregon Basin and Line Creek thrust faults. These folds involve sedimentary rocks ranging from Paleozoic through Paleocene in age, are typically asymmetric, commonly thrust fault-bounded along their steep flanks, and ...Anticlines and synclines. An anticline is a fold that is arched upward to form a ridge; a syncline is a fold that arches downward to form a trough (Figure ). Anticlines and synclines are usually made up of many rock units that are folded in the same pattern. The tip of a fold is called the nose.An Oil Finders Glossary; Anticlines - When layers of rock are folded to create a dome, the resulting geometry is called an anticline. Because oil floats on water, the oil tries to move to the top of the anticline. If an impermeable seal, such as a shale bed, caps the dome, then a pool of oil may form at the crest.Elk Hills field in the San Joaquin Valley is an example of an anticline.Cross-section over the Wealden anticline.
