Garber Sandstone
The Garber Sandstone is a geologic formation from the Permian Period in Oklahoma. It serves as an important aquifer, the Garber-Wellington Aquifer, in Logan, Oklahoma, and Cleveland counties of central Oklahoma. The upper portion of the Garber is associated with extensive baryte mineralization associated with desert rose occurrences in the outcrop area.''Review of the General Geology and Solid-Phase Geochemical Studies in the Vicinity of the Central Oklahoma Aquifer,'' US Geological Survey Circular 1019, 1986, p. 6 See also * List of fossiliferous stratigraphic units in Oklahoma This article contains a list of fossil-bearing stratigraphic units in the state of Oklahoma, U.S. Sites See also * Paleontology in Oklahoma References * List of Formations in the National Geologic Map Database {{DEFAULTSORT:Fossilifer ...

Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Period (geology)
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Desert Rose (crystal)
A desert rose is an intricate rose-like formation of crystal clusters of gypsum or baryte, which include abundant sand grains. The "petals" are crystals flattened on the ''c'' axis, fanning open in radiating clusters. The rosette crystal habit tends to occur when the crystals form in arid sandy conditions, such as the evaporation of a shallow salt basin. The crystals form a circular array of flat plates, giving the rock a shape similar to a rose blossom. Gypsum roses usually have better defined, sharper edges than baryte roses. Celestine and other bladed evaporite minerals may also form rosette clusters. They can appear either as a single rose-like bloom or as clusters of blooms, typically ranging from pea-sized to in diameter. The ambient sand that is incorporated into the crystal structure, or otherwise encrusts the crystals, varies with the local environment. If iron oxides are present, the rosettes take on a rusty tone. The desert rose may also be known by the nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baryte
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate ( Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4. Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England.

Cleveland County, Oklahoma
Cleveland County is a county in the central part of the U.S. state of Oklahoma. The population was 295,528 at the 2020 United States Census, making it the third-most populous county in Oklahoma. Its county seat is Norman. The county was named for U.S. President Grover Cleveland.Wilson, Linda D"Cleveland County,"''Encyclopedia of Oklahoma History and Culture'', 2009. Accessed March 28, 2015. Cleveland County is part of the Oklahoma City Metropolitan Statistical Area. History Originally occupied by the Quapaw tribe, the Quapaw ceded the area to the U.S. Government soon after the Louisiana Purchase in 1818. During the late 1820s and 1830s, the area was given to the Creek and Seminole tribes after their forced removal from the southeastern United States. An agreement between the two tribes resulted in this area being part of the Seminole Nation, located west of the Creek Nation. In 1866, these tribes were forced to cede the area to the Federal Government; the professed rationale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oklahoma County, Oklahoma
Oklahoma County is located in the central part of the U.S. state of Oklahoma. As of the 2010 census, the population was 718,633, making it the most populous county in Oklahoma. The county seat is Oklahoma City, the state capital and largest city. Oklahoma County is at the heart of the Oklahoma City Metropolitan Statistical Area. Oklahoma County is one of seven counties in the United States to share the same name as the state it is located in (the other six being Arkansas County, Hawaii County, Idaho County, Iowa County, New York County (Manhattan), and Utah County), and the only one of the seven to contain the state capital, and one of two to contain a city of the same name as well. History The area that would someday be called Oklahoma County was originally inhabited by members of the indigenous nations of the Southern Plains, but by the 1830s the land would become part of the territory assigned to the Seminoles and Creeks after their removal from their ancestral lands ...

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
