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. Formation [ edit ]
They occur as single isolated folds or in periodic sets (known as fold trains). Synsedimentary folds are those formed during sedimentary deposition. Folds form under varied conditions of stress , pore pressure , and temperature gradient , as evidenced by their presence in soft sediments , the full spectrum of metamorphic rocks , and even as ...
Geological map of the Isle of Wight. The geology of the Isle of Wight is dominated by sedimentary rocks of Cretaceous and Paleogene age. This sequence was affected by the late stages of the Alpine Orogeny, forming the Isle of Wight monocline, the cause of the steeply-dipping outcrops of the Chalk Group and overlying Paleogene strata seen at The Needles, Alum Bay and Whitecliff Bay.
It is formed by the more erosion-resistant sandstones of the Dakota Formation protecting the softer, less erosion-resistant strata of the Morrison Formation. Hogsback up Bald Mountain, in the Adirondacks of New York. Dinosaur Ridge is a well known hogback that is part of Morrison Fossil Area National Natural Landmark within Morrison, Colorado.

Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
Comb Ridge (Navajo: Tséyíkʼáán) [1] is a linear north to south-trending monocline nearly 80 miles long in Southeastern Utah and Northeastern Arizona. Its northern end merges with the Abajo Mountains some eleven miles west of Blanding. It extends essentially due south for 45 km (28 mi) to the San Juan River.
