Dome (geology) in the context of "Colorado Plateau"

The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, and Oklahoma, as well as a small area in the southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri.

There are two mountain ranges in the Ozarks: the Boston Mountains of Arkansas and Oklahoma, as well as the St. Francois Mountains of Missouri. Wahzhazhe Summit (formerly known as Buffalo Lookout), is the highest point in the Ozarks at 2,561 feet (781 m), and is located in the Boston Mountains, in the westernmost part of Newton County, Arkansas, 6.2 miles (10.0 km) east of Boston, Madison County, Arkansas. Geologically, the area is a broad dome with the exposed core in the ancient St. Francois Mountains. The Ozarks cover nearly 47,000 square miles (120,000 km), making it the most extensive highland region between the Appalachians and Rockies. Together with the Ouachita Mountains, the area is known as the U.S. Interior Highlands.

A structural basin is a large-scale structural formation of rock strata formed by tectonic warping (folding) of previously flat-lying strata into a syncline fold. They are geological depressions, the inverse of domes. Elongated structural basins are a type of geological trough. Some structural basins are sedimentary basins, aggregations of sediment that filled up a depression or accumulated in an area; others were formed by tectonic events long after the sedimentary layers were deposited.

Basins may appear on a geologic map as roughly circular or elliptical, with concentric layers. Because the strata dip toward the center, the exposed strata in a basin are progressively younger from the outside in, with the youngest rocks in the center. Basins are often large in areal extent, often hundreds of kilometers across.

The Miralga impact structure is an impact structure in the Pilbara Craton of Western Australia. With an initially estimated age of around 3.47 billion years dating to the Paleoarchean, it has been suggested to be the oldest known impact structure on Earth by over a billion years and the only one known from the Archean.

The structure is found in the East Pilbara Terrane, one of the oldest parts of the Pilbara Craton. The structure lies on a geological dome called the North Pole Dome which was initially suggested to represent the central uplift of the structure. Evidence of the impact is shatter cones found in the Antarctic Creek Member, a 20 metres (66 ft) thick layer of sedimentary rock including "felsic to mafic volcaniclastic rocks, chert, argillite, arenite and jaspilite intruded by dolerite", sandwiched between overlying and underlying volcanic rocks of the Mount Ada Basalt Basalt, which is 2–3 kilometres (1.2–1.9 mi) thick.

The Eastern Pilbara Craton is the eastern portion of the Pilbara Craton located in Western Australia. This region contains variably metamorphosed mafic and ultramafic greenstone belt rocks, intrusive granitic dome structures, and volcanic sedimentary rocks. These greenstone belts worldwide are thought to be the remnants of ancient volcanic belts, and are subject to much debate in today's scientific community. Areas such as Isua and Barberton which have similar lithologies and ages as Pilbara have been argued to be subduction accretion arcs, while others suggest that they are the result of vertical tectonics. This debate is crucial to investigating when/how plate tectonics began on Earth. The Pilbara Craton along with the Kaapvaal Craton are the only remaining areas of the Earth with pristine 3.6–2.5 Ga crust. The extremely old and rare nature of this crustal region makes it a valuable resource in the understanding of the evolution of the Archean Earth.

A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps.

A Kuppe is the term used in German-speaking central Europe for a mountain or hill with a rounded summit that has no rock formation, such as a tor, on it. A range of such hills is called a Kuppengebirge. In geology the term also refers to corresponding stratigraphic forms. The term is similar to the English topographical and geological terms, knoll and dome. It is also analogous to the French word ballon which means a mountain with a rounded summit.

In cartography in German-speaking countries, the term is used more widely to refer to all eminences (biaxially convex landforms) i.e. including those with a more pointed appearance.
