Chevron: angular fold with straight limbs and small hinges; Slump: typically monoclinal, the result of differential compaction or dissolution during sedimentation and lithification. Ptygmatic: Folds are chaotic, random and disconnected. Typical of sedimentary slump folding, migmatites and decollement detachment zones.
Cove – Small sheltered bay or coastal inlet; Cuspate foreland – Geographical features found on coastlines and lakeshores; Dune system – Hill of loose sand built by aeolian processes or the flow of water; Estuary – Partially enclosed coastal body of brackish water; Firth – Scottish word used for various coastal inlets and straits
Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills , mountains , canyons , and valleys , as well as shoreline features such as bays , peninsulas , and seas , [ 3 ] including submerged features such as mid-ocean ridges , volcanoes , and the great ocean basins .
Atolls like Atafu in Tokelau in the Pacific Ocean are landforms associated to tropical climate. No atoll exists outside the tropics. Climatic geomorphology is the study of the role of climate in shaping landforms and the earth-surface processes. [1] An approach used in climatic geomorphology is to study relict landforms to infer ancient ...
Badlands incised into shale at the foot of the North Caineville Plateau, Utah, within the pass carved by the Fremont River and known as the Blue Gate. G. K. Gilbert studied the landscapes of this area in great detail, forming the observational foundation for many of his studies on geomorphology. [1]
Diastrophism is the process of deformation of the Earth's crust which involves folding and faulting. Diastrophism can be considered part of geotectonics. The word is derived from the Greek διαστροϕή diastrophḗ 'distortion, dislocation'. [1]
Both are intruded by granites associated with the Iwokrama Formation. Some folding occurred before these were overlain by the locally unconformable almost flat lying Roraima Group. [1] Major mafic sills and dykes of the Avanavero Suite intrude all of the older rocks, and are part of a Large Igneous Province (LIP). [2]
Klippe of Hronic nappe, Mt. Vápeč, Strážovské vrchy Mts., Slovakia. Nappe can be qualified in a number of ways to indicate various features of a formation. The frontal part in the direction of movement, is called the leading edge of a nappe; numerous folds and secondary thrusts and duplexes are common features here and are sometimes called digitations.
