The formula for making it (using
clay and then firing it at temperatures above 1100 °C) was kept a closely guarded secret.
In southwestern Alberta around the Red Deer and Oldman Rivers, the middle carbonaceous shale unit is absent and the formation consists of white-weathering, cross-bedded
sandstones interbedded with white- to cream-weathering silty and sandy clay.
Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths – regoliths are the loose layer of rocks that rest on the bedrock – saprolite may be overlain by upper horizons of residual laterite; most of the original profile is preserved by residual soils or transported overburden. Weathering formed thin
[AlSiO(OH)] saprolites 1,000 to 500 million years ago; thick
saprolites 200 to 66 million years ago; and medium-thick immature saprolites 5 million years ago. The general structure of kaolinite has silicate [SiO] sheets bonded to aluminium hydroxide [Al(OH)] layers.
Donnybrook stone is a fine to medium-grained feldspathic and
sandstone found near the town of Donnybrook, Western Australia. It originates from the early Cretaceous (144-132 MYA) and features shale partings and colour variations which range from white to beige and pink.
The Bovey Formation is the major source in England for ball clay – a highly plastic fine-grained
sedimentary clay typically used by the pottery industry. Large excavations have been made for the extraction of these clays. In the past, the lignite or "Bovey Coal" was burned in local kilns; steam engines; and workmen's cottages. It was, however, not economical.
The most characteristic wares are thin porcelains with a white or greyish body and a nearly transparent white-tinted glaze, though they are classed as stoneware by some. Chemical analysis has shown that they were often made entirely of a
clay without any petuntse or "porcelain stone". They are mostly decorated, with uncoloured designs that are incised or in very shallow relief.
The tertiary highland is composed of some clay layers (Belterra clay) of
sediments of a Pliocene lake, with a distinct escarpment to the North and West of the plain, which leads down to the Várzea forest lowland at the river bank of the Tapajos river.
Ultisols can have a variety of clay minerals, but in many cases the dominant mineral is kaolinite. This clay has good bearing capacity and no shrink–swell property. Consequently, well-drained
ultisols such as the Cecil series are suitable for urban development.
The Whitemud Formation is a geologic formation of Late Cretaceous (Maastrichtian) age in the Western Canada Sedimentary Basin. it is present through the plains of southern Saskatchewan, southeastern Alberta and south-central Alberta. Named by N.B. Davis in 1918, the formation is characterized by white
clay and is a source of high-quality refractory clay. The type locality has been designated as Dempster's clay pit northwest of Eastend, Saskatchewan.
The base of the Bear Den Member consists of
claystone, mudstone and sandstone that weather to white, light grey, orange, and purple. These are overlain by grey or brownish carbonaceous sediments and, in some areas, a bed of lignite (the "Alamo Bluff lignite"). In places the sequence is capped by a siliceous bed (the "Taylor bed") that represents a weathering surface or paleosol. The Bear Den Member reaches a maximum thickness of about .
Ball clays are
sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters.
A Hessian crucible is a type of ceramic crucible that was manufactured in the Hesse region of Germany from the late Middle Ages through the Renaissance period. They were renowned for their ability to withstand very high temperatures, rapid changes in temperature, and strong reagents. These crucibles were widely used for alchemy and early metallurgy. Millions of the vessels were exported throughout Europe, Scandinavia, and the colonies in the Americas. The crucibles were made by firing
clay at temperatures greater than 1100℃, forming mullite. Mullite is an aluminum silicate only described in the 20th century and is responsible for the excellent properties of the Hessian crucible.
The Haile deposit was discovered in Lancaster County in 1827, and at least of gold were extracted intermittently between then and 1942, when the gold mine was ordered closed as nonessential to the war effort. Beginning in 1951, the deposit was mined for associated sericite, which was used as a white filler. Gold is associated with silicic,
, and pyritic alteration of greenschist-grade felsic metavolcanics. The mine was reopened as an open pit in the 1980s, and operated until 1992. Kinross Gold Corporation's reclamation of the Haile site was nominated for a US Bureau of Land Management "Hardrock Mineral Environmental Award."
The first geopolymer resin was described in a French patent application filed by J. Davidovits in 1979. The American patent, US 4,349,386, was granted on Sept. 14, 1982 with the title "Mineral Polymers and methods of making them". It essentially involved the geopolymerization of alkaline soluble silicate [waterglass or (Na,K)-polysiloxonate] with calcined
clay (later coined metakaolin MK-750 to highlight the importance of the temperature of calcination, namely 750 °C in this case). In 1985, Kenneth MacKenzie and his team from New-Zealand, discovered the Al(V) coordination of calcined kaolinite (MK-750). This had a great input towards a better understanding of its geopolymeric reactivity.
In general, artificial cement is made from limestone, clay and gypsum (natural cements are obtained from rocks containing lime and clay). The main components are lime and
clay. There are some cements such as the aluminous, derived from aluminous and lime materials, that are black (melanocratic). The presence of aluminum in the analysis of the Bélmez face called "El Pelao" (The bald one) could indicate that an aluminum-type cement was being dealt with. However, in his report Alonso does not indicate the percentage of said cation, nor its structure, resistance to compression, elasticity module, chemical resistance or other characteristics necessary to differentiate a Portland cement from an aluminum cement.
]Originally mapped in Cecil County, Maryland in 1899, more than 10 million acres (40,000 km²) of the Cecil soil series (Fine,
, thermic Typic Kanhapludults) are now mapped in the Piedmont region of the southeastern United States. It extends from Virginia through North Carolina (where it is the state soil), South Carolina, Georgia and Alabama, with the typic Cecil pedon actually located in Franklin County, NC. A map showing the actual extent of the Cecil series is available at the Center for Environmental Informatics
The river is too erratic for hydroelectricity to be viable and the soils are exceedingly infertile – generally ironstone gravels or
clays – the combined Gilbert-Einasleigh River system is one of the relatively few completely free-flowing river systems of its size or greater in the world. Most of the basin is natural grassland used for grazing cattle at the extremely low densities permissible with the very low nutritive qualities of the feed available: the population is no more than one thousand or one person for over . In the upper reaches soils are more fertile red cracking clays but erode too easily under the erratic rainfall for cropping to be a likely prospect even with groundwater available. The mouth of the river lies in the Gulf Plains Important Bird Area.
A briefly popular theory held that a C-rich comet struck the earth and initiated the warming event. A cometary impact coincident with the P/E boundary can also help explain some enigmatic features associated with this event, such as the iridium anomaly at Zumaia, the abrupt appearance of
clays with abundant magnetic nanoparticles on the coastal shelf of New Jersey, and especially the nearly simultaneous onset of the carbon isotope excursion and the thermal maximum. Indeed, a key feature and testable prediction of a comet impact is that it should produce virtually instantaneous environmental effects in the atmosphere and surface ocean with later repercussions in the deeper ocean. Even allowing for feedback processes, this would require at least 100 gigatons of extraterrestrial carbon. Such a catastrophic impact should have left its mark on the globe. Unfortunately, the evidence put forward does not stand up to scrutiny. An unusual 9-meter-thick clay layer supposedly formed soon after the impact, containing unusual amounts of magnetite, but it formed too slowly for these magnetic particles to have been a result of the comet's impact, and it turns out they were created by bacteria. However, recent analyses have shown that isolated particles of non-biogenic origin make up the majority of the magnetic particles in the thick clay unit.
Fossils from the front of a snout of plesiosaur were discovered in 2000 on the property of Jorge Muñoz, in Loma La Cabrera, near Villa de Leyva in Boyaca, Colombia, on grounds of marine origin dating from the Barremian epoch of the Cretaceous. Muñoz reported the find to the local authorities, who in turn gave notice to staff of the "Museo Geológico José Royo y Gómez" in the Colombian Geological Survey in Bogotá. Then was made the excavation of the nearly complete skeleton between 2004 and 2005, in collaboration with the Fundación Colombiana de Geobiología ("Colombian Geobiology Foundation"), and the remains being then transferred to Bogotá, assigning the catalog number VL17052004-1, for preparation and study. The remains were found articulated mostly in the Segment C of Member Arcillolitas Abigarradas of the Paja Formation, with
argillite corresponding to an intertidal marine environment, with several specimens of ammonites or impressions of these in the rock matrix, including one inside the skull. These ammonites include the species "Gerhardtia galeatoides", "G. provincialis" and the genus "Heinzia", typical of the Barremian. German paleontologist Oliver Hampe made an initial description of the specimen in 2005, classifying it as "Brachauchenius" sp., i.e. as an indeterminate species of this genus, previously only recorded in the Upper Cretaceous of the United States, and it constitute the first reappearance of non-rhomaleosaurid pliosaurs after a hiatus between the Berriasian to Hauterivian. In 2016 María Páramo, Marcela Gómez-Pérez, Fernando Etayo and Leslie Noé made a more complete description and they designated to VL17052004-1 as holotype of a new genus and species, "Stenorhynchosaurus munozi". The genus name is derived from the Greek words "stenos", "narrow"; "rhyncho", "snout" and "saurus", "lizard", while the species name, "munozi" is in recognition of Jorge Muñoz by discover and report the fossil.
Nearby there are campgrounds available, and a point of information regarding the crossing of Poplar River. The area is rich in history, this is the Big Muddy Badlands area which featured the hideouts of outlaws and rum runners of the nineteenth and early twentieth century. This area remained above the Quaternary age ice sheets, being pushed and folded by the glacier movement resulting in glaciotectonic hills. The highway winds up, down and around these hills along the way. The Big Muddy Badlands are within the Missouri Coteau. At km 12.2 the highway reaches Kildeer, and the intersection with Highway 18. Access to Wood Mountain Post Provincial Historical Park is obtained by following Highway 18 north for . This section of Highway 2 begins as a Class 4 highway and is under the jurisdiction of the Saskatchewan Highways and Transportation (SHT) South West Transportation Planning Council. The highway is a secondary weight highway with a thin membrane surface type as it only has an average of 390 vehicles per day (vpd) according to the 2007 Average Annual Daily Traffic (AADT) count which was taken north of Rockglen. Highway 2 begins a concurrency with Highway 18 in a northeasterly direction. Alfalfa and alfalfa mixtures, hay and fodder crops and spring wheat are the main crops in Old Post rural municipality (RM). There is a point of information at km 42.3. This area is known as the Wood Mountain Uplands where there are mining endeavours undertaken such as coal, bentonite,
and ceramic clays. Paleontological digs have uncovered a 63-million-year-old sea turtle which has been excavated in the Killdeer region. Rockglen is located at km 49.7, and Highway 2 now extends in a northerly direction again. Rockglen (Population 450 in 2001 and 360 in 2006 ) and Assiniboia ( 2,483 in 2001 and 2,305 in 2006 ) are the two largest centers between the border and the city of Moose Jaw. This geographical region of Highway 2 from Rockglen to Assiniboia has been upgraded to a Class 3 highway as it carries approximately 800 vehicles per day counted to the south of Assiniboia. Therefore, the surface type before Assiniboia is a granular road surface which is a structural pavement with a hot mix surface coating. The highway type, surface, maintenance and construction projects are looked after by the SHS South Central Traffic Planning Committee. Fife Lake is located to the north east of the highway. The St. Victor Petroglyph Historic Park is located just to the west of Highway 2 by . These unique petroglyph features carved into the sandstone are slowly disappearing. At is the town of Assiniboia where 1,260 vpd results in the highway designated as an asphalt concrete (AS) Class 2 primary weight highway all the way to Moose Jaw. Junction with Highway 13, the Redcoat Trail occurs at km 106.4, providing access to Lafleche. Vantage is located to the west of the highway along this stretch, with access provided at km 129.2. Mossbank is located at the intersection with Highway 718. Here is the southeast portion of Old Wives Lake, which is a part of the Chaplin, Old Wives Lake, Reed Lakes ("Hemispheric") - Western Hemisphere Shorebird Reserve Network ("WHSRN") Site, a designated Hemispheric Shorebird Reserve Network, protecting three saline lakes, saline and freshwater marshes. Ardill is located near the northern extremity of Lake of the Rivers. Highway 36 is located at km 176.4, which provides access to Crestwynd, and the Jean Louis Legare Regional Park. At km 184.5, is the junction with Highway 716 west providing access to Briercrest.
