Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct ...

Chrysoberyl
The mineral or gemstone chrysoberyl is an aluminate of beryllium with the formula Be Al2 O4. The name chrysoberyl is derived from the Greek words χρυσός ''chrysos'' and βήρυλλος ''beryllos'', meaning "a gold-white spar". Despite the similarity of their names, chrysoberyl and beryl are two completely different gemstones, although they both contain beryllium. Chrysoberyl is the third-hardest frequently encountered natural gemstone and lies at 8.5 on the Mohs scale of mineral hardness, between corundum (9) and topaz (8). An interesting feature of its crystals are the cyclic twins called ''trillings''. These twinned crystals have a hexagonal appearance, but are the result of a triplet of twins with each "twin" oriented at 120° to its neighbors and taking up 120° of the cyclic trilling. If only two of the three possible twin orientations are present, a "V"-shaped twin results. Ordinary chrysoberyl is yellowish-green and transparent to translucent. When the mineral e ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Andersonite
Andersonite, Na2Ca(UO2)(CO3)3·6H2O, or hydrated sodium calcium uranyl carbonate is a rare uranium carbonate mineral that was first described in 1948. Named after Charles Alfred Anderson (1902–1990) of the United States Geological Survey, who first described the mineral species, it is found in sandstone-hosted uranium deposits. It has a high vitreous to pearly luster and is fluorescent. Andersonite specimens will usually glow a bright lemon yellow (or green with blue hints depending on the deposit) in ultraviolet light. It is commonly found as translucent small rhombohedral crystals that have angles close to 90 degrees although its crystal system is nominally trigonal. Its Mohs hardness is 2.5, with an average specific gravity of 2.8. It occurs in the oxidized zone of uranium-bearing polymetallic ore deposits. It also may occur as an efflorescent crust on the walls and timbers of uranium mines. As this mineral is water-soluble, samples must be stored in dry conditions. It occ ...

Fernando Flávio Marques De Almeida
Fernando Flávio Marques de Almeida (February 18, 1916 – August 2, 2013) was a Brazilian geologist considered to be one of the top Brazilians concerned with the study. Almeida did the central works to understand the South American geology. He is the son of the first Brazilian generation of geologists who did the pioneering papers of the continent's geology. Marques de Almeida is a member of the Brazilian Academy of Sciences. Born in Rio de Janeiro in 1916, his parents were the lawyer Gerson de Almeida and Nair Marques de Almeida. He did his primary and secondary studies at the Gymnasium of São Bento in São Paulo state in which he spent most of his life. Finished junior high school did tender for the Polytechnic School of São Paulo, where he graduated in Civil Engineering in 1938. Had much influence on his future career Professor Dr. Luiz Flores de Moraes Rego, Professor of Mineralogy, Petrography and geology of this school. To finish the school year in which he attended a ...

It is currently only found in Italy. It was discovered by and named for the Italian mineralogist Roberto Allori, an avid mineral collector who has also done research on piergorite and willhendersonite. The mineral appears as a crystal that is approximately 1.5 by 2mm in length. The crystal grows as both tabular and prismatic crystals, and commonly occurs with sanidine, biotite, andradite, and apatite. It was approved of being a mineral in 2006 by the International Mineralogical Association. Afghanite is a cancrinite group mineral that is very similar to alloriite in both its ...

Thomas Allan (mineralogist)
Thomas Allan of Lauriston FRS FRSE FSA FLS (17 July 1777 – 12 September 1833) was a British mineralogist. Life Allan was born in Edinburgh, Scotland, on 17 July 1777, the son of Robert Allan (1748–1818), a banker. He was educated at the High School of Edinburgh and took up banking as profession; but he is remembered today for his contributions to mineral science. At an early age Allan became fascinated with minerals and he began to accumulate a large mineral collection that was subsequently bequeathed to his son Robert Allan FRSE. This collection was later incorporated into Robert Greg's, which was ultimately acquired by the British Museum of Natural History in the mid-nineteenth century. In 1813, Allan was influential in securing a mineralogy post in the Dublin Philosophical Society for the German mineralogist Karl Ludwig Giesecke (1761–1833). Allan was elected as Fellow of the Royal Society of Edinburgh in 1805, his proposers being Sir James Hall, William Wright and J ...

Allanite
Allanite (also called orthite) is a sorosilicate group of minerals within the broader epidote group that contain a significant amount of rare-earth elements. The mineral occurs mainly in metamorphosed clay-rich sediments and felsic igneous rocks. It has the general formula A2M3Si3O12 H where the A sites can contain large cations such as Ca2+, Sr2+, and rare-earth elements, and the M sites admit Al3+, Fe3+, Mn3+, Fe2+, or Mg2+ among others. However, a large amount of additional elements, including Th, U, Be, Zr, P, Ba, Cr and others may be present in the mineral. The International Mineralogical Association lists four minerals in the allanite group, each recognized as a unique mineral: allanite-(Ce), allanite-(La), allanite-(Nd), and allanite-(Y), depending on the dominant rare earth present: cerium, lanthanum, neodymium or yttrium. Allanite contains up to 20% rare-earth elements and is a valuable source of them. The inclusion of thorium and other radioactive elements in allanite re ...
