Smackover Formation
The Smackover Formation is a geologic formation in Arkansas. It preserves fossils A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in ... dating back to the Jurassic Period (geology), period. The Smackover Formation consists of oolitic limestones and silty limestones. Mineral resources The Smackover Formation has been a prolific source of petroleum. The 1922 discovery of the Smackover, Arkansas#Smackover Oil Field, Smackover oil field, after which the Smackover Formation is named, resulted in a sizeable oil boom in southern Arkansas. In addition to being a petroleum reservoir, as of 2015, the brine from the Smackover Formation is the only source of commercial bromine in the United States. A 2022 report estimated that the lithium brine in the formation has "sufficient lithium to pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Smackover, Arkansas
Smackover is a small city in northern Union County, Arkansas, Union County, Arkansas, United States. According to the 2010 census, the population was at 1,865. It had a large oil boom in the 1920s, with production continuing for some time. History In 1686, the French settlers called this area ''"Sumac Couvert"'', which translates to "covered in Sumac, sumac bushes". This was transliterated, that is, phonetically Anglicized by the English-speaking settlers of the 19th century and later to the name "Smackover." The name Bayou de Chemin Couvert (Smackover Creek) first appeared in an April 5, 1789, letter written by the commandant of Fort Miro (Monroe, Louisiana) to the French territorial governor. Oil was discovered in this area in 1922; it attracted national attention, speculators, and an economic boom. Smackover was incorporated in 1923. In the 1920s there was a large-scale oil industry in Smackover. The industry declined here and across southern Arkansas by the 1960s, at a cost ...

Brine Mining
Brine mining is the extraction of useful materials ( elements or compounds) which are naturally dissolved in brine. The brine may be seawater, other surface water, groundwater, or hyper-saline solutions from several industries (e.g., textile industries). It differs from solution mining or in-situ leaching in that those methods inject water or chemicals to dissolve materials which are in a solid state; in brine mining, the materials are already dissolved. Brines are important sources of common salt (NaCl), calcium, iodine, lithium, magnesium, potassium, bromine, and other materials, and are potentially important sources of a number of others. Brine mining supports waste minimization and resource recovery efforts. History Around 500 BC, the ancient Chinese dug hundreds of brine wells, some of which were over 100 meters (330 feet) in depth. Large brine deposits under the earth's surface were drilled by drilling boreholes.Tom (1989), 103. Bamboo towers were erected, similar in style ...

Lithium
Lithium (from el, λίθος, lithos, lit=stone) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such as purified kerosene or mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals, which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines. Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromine Production In The United States
__NOTOC__ Bromine production in the United States of 225,000 tonnes in 2013 made that country the second-largest producer of bromine, after Israel. The US supplied 29 percent of world production. Since 2007, all US bromine has been produced by two companies in southern Arkansas, which extract bromine from brine pumped from the Smackover Formation. At an advertised price of US$3.50 to US$3.90 per kg, the US 2013 US production would have a value of roughly US$800 million. The two active bromine producers are Albemarle Corporation and Chemtura, whose bromine operations together employ 950 people. Albemarle Corporation, whose corporate headquarters is in Charlotte, North Carolina, operates two main plants at Magnolia, in Columbia County, Arkansas, and some satellite plants in Union County. In 2007, Albemarle had capacity to produce 148,000 tons of bromine per year. Chemtura, a Philadelphia-based corporation, operates four plants through its subsidiary, Great Lakes Solutions.

Paleontology In Arkansas
Paleontology in Arkansas refers to paleontological research occurring within or conducted by people from the United States, U.S. state of Arkansas. The fossil Fossil record, record of Arkansas spans from the Ordovician to the Eocene. Nearly all of the state's fossils have come from ancient invertebrate life. During the early Paleozoic, much of Arkansas was covered by seawater. This sea would come to be home to creatures including ''Archimedes (bryozoan), Archimedes'', brachiopods, and conodonts. This sea would begin its withdrawal during the Carboniferous, and by the Permian the entire state was dry land. Landform, Terrestrial conditions continued into the Triassic, but during the Jurassic, another sea encroached into the state's southern half. During the Cretaceous the state was still covered by seawater and home to marine invertebrates such as ''Belemnitella''. On land the state was home to long necked sauropod dinosaurs, who left behind footprints and ostrich dinosaurs such as ''A ...

Electric Vehicle Battery
An electric vehicle battery (EVB, also known as a traction battery) is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). Typically lithium-ion batteries, they are specifically designed for high electric charge (or energy) capacity. Electric vehicle batteries differ from starting, lighting, and ignition (SLI) batteries as they are designed to give power over sustained periods of time and are deep-cycle batteries. Batteries for electric vehicles are characterized by their relatively high power-to-weight ratio, specific energy and energy density; smaller, lighter batteries are desirable because they reduce the weight of the vehicle and therefore improve its performance. Compared to liquid fuels, most current battery technologies have much lower specific energy, and this often impacts the maximum all-electric range of the vehicles. The most common battery type in modern electric vehicles are lithium-ion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bromine
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest element in group 17 of the periodic table (halogens) and is a volatile red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek (bromos) meaning "stench", referring to its sharp and pungent smell. Elemental bromine is very reactive and thus does not occur as a native element in nature but it occurs in colourless soluble crystalline mineral halide salts, analogous to table salt. In fact, bromine and all the halogens are so reactive that they form bonds in pairs—never in single atoms. While it is rather rare in the Earth's crust, the high solubility of the bromide ion (Br) has caused its accumulation in the oceans. Commercial ...
