Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its low density after processing.
A spring is a point at which water flows from an aquifer to the Earth's surface. It is a component of the hydrosphere.
Hardystonite is a rare calcium zinc silicate mineral first described from the Franklin, New Jersey, U.S. zinc deposits. It often contains lead, which was detrimental to the zinc smelting process, so it was not a useful ore mineral. Like many of the famous Franklin minerals, hardystonite responds to short wave ultraviolet light, emitting a fluorescence from dark purple to bright violet blue. In daylight, it is white to gray to light pink in color, sometimes with a vitreous or greasy luster. It is very rarely found as well formed crystals, and these are usually rectangular in appearance and rock-locked.
Kramer is a small unincorporated community in Liberty Township, Warren County, in the U.S. state of Indiana.
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and roadside edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties, or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.
Alba Township is one of twenty-four townships in Henry County, Illinois, USA. As of the 2010 census, its population was 220 and it contained 95 housing units. Alba Township changed its name from Elba Township on April 13, 1857. The name may be derived from Elba, New York, the native home of a share of the early settlers.
Richland Township is one of fifteen townships in Greene County, Indiana, USA. As of the 2010 census, its population was 5,019.
Bath Township is one of 13 townships in Franklin County, Indiana. As of the 2010 census, its population was 369.
Dodge Township is one of seventeen townships in Boone County, Iowa, USA. As of the 2000 census, its population was 540.
Mineral Township is one of twenty-five townships in Barry County, Missouri, United States. As of the 2000 census, its population was 886.
The Ordovician Kittatinny Formation or Kittatinny Limestone is a dolomitic limestone formation in New Jersey. The Kittatinny Limestones are located primarily in the Kittatinny Valley where it lies above the Ordovician Martinsburg Formation within the long valley running from Picatinny Arsenal in Rockaway Township, southwest toward Chester Township. It overlies the Cambrian Hardyston Quartzite.
Schumer Springs is an unincorporated community in southern Cinque Hommes Township in Perry County, Missouri.
Ogygis Undae is the only named southern hemisphere dune field on Mars. It is named after one of the classical albedo features on Mars: Ogygis Regio. Its name was officially approved by the International Astronomical Union (IAU) on 17 September 2015. Its name is Greek, and derives from the name of Ogyges, a primeval mythological ruler in ancient Greece. The dunes of Ogygis Undae extend from latitude −49.94°N to −49.37°N and from longitude 292.64°E to 294.93°E. Its centre is located at latitude −49.66°N, longitude 293.79°E (66.21°W), and has a diameter of 87.7 km. It is situated just outside Argyre Planitia, a plain located in the southern highlands of Mars. Ogygis Undae has an area of 1904 km2, and, because to its large size, it is considered to be an excellent field on which research on dune morphology and sand composition, using data which has been gathered by the various instruments onboard robotic spacecraft sent by NASA and ESA to Mars.
