Rose Rock
A desert rose, sand rose, Sahara rose, rose rock, selenite rose, gypsum rose, or baryte 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, ...

Roses Des Sables Tunisie
A rose is either a woody perennial plant, perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred Rose species, species and Garden roses, tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp Thorns, spines, and prickles, prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through pinks, reds, oranges and yellows. Most species are native to Asia, with smaller numbers native to Europe, North America, and Northwest Africa. Species, cultivars and hybrid (biology), hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses to climbers that can reach seven meters in height. Different species hybridize easily, and this has been use ...

Evaporite
An evaporite () is a water- soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments. Formation Although all water bodies on the surface and in aquifers contain dissolved salts, the water must evaporate into the atmosphere for the minerals to precipitate. For this to happen, the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small drainage basin fed by a limited input of water. When evaporation occurs, the remaining water is enriched in salts, and they precipitate after the water becomes saturated. Depositional environments ...

Noble, Oklahoma
Noble is a city in Cleveland County, Oklahoma, United States, and is part of the Oklahoma City Metropolitan Area. The population was 6,985 at the 2020 census, a 7.8% increase from 2010. Noble is Cleveland County's third-largest city behind Norman and Moore. History On April 22, 1889, the day the first Oklahoma "Land Run" opened the Unassigned Lands in the middle of Indian Territory to settlers, J.W. Klinglesmith, Albert Rennie and several other businessmen forded the South Canadian River and laid claim to the town site that was to become Noble. The town was named in honor of Secretary of the Interior John Noble, who was instrumental in opening the Unassigned Lands to settlement. The group had great plans for Noble, hoping it would become the future county seat. The Santa Fe Railroad completed a railroad depot in Noble in August 1889. For several years, Noble was a major shipping point for cattle and other goods from both sides of the Canadian River. Business prospered e ...

Oklahoma Geological Survey
The Oklahoma Geological Survey is a state agency chartered in the Constitution of Oklahoma responsible for collecting and disseminating information about Oklahoma's natural resources, geological formations, and earthquakes. Shortly after Oklahoma became a state, its first legislature passed an enabling act on May 29, 1908 and Governor Charles Haskell signed it into law. The OGS was an offshoot of Oklahoma Territory's Territorial Survey, which was established in 1900. OGS remains the only state geological survey that was created by a provision in the state constitution. In 1924, jurisdiction of the OGS was officially put under the Oklahoma University Board of Regents, and has not been changed since. In 2007, OGS became part of the Mewbourne College of Earth and Energy. History The Oklahoma Geological Society was established on the Oklahoma University campus under an agreement between OU geology professor, Charles N. Gould, and the OU Dean of Arts and Sciences, Professor James ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and System (stratigraphy), 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 251.902 Mya. It is the sixth and 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 Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
