Mineralogy

Searles Lake is a huge resource of sodium and potassium minerals of the carbonate, sulfate, borate and halide classes of mineralogy. The manufacture of industrial minerals involves a complex solution mining operation in which naturally occurring brines are pumped from wells completed in several salt beds. The brine wells range in depth from near-surface to over 100 meters below the salt pan. A network of production wells, injection wells, solar ponds and piping are used in ...

Lamproites are characterized by the presence of widely varying amounts (5-90 vol.%) of the following primary phases (Mitchell & Bergman, 1991): titanian (2-10 wt% TiO2), aluminum-poor (5-12 wt% Al2O3) phenocrystic phlogopite titanian (5-10 wt% TiO2) groundmass poikilitic "tetraferriphlogopite" titanian (3-5 wt% TiO2) potassium (4-6 wt% K2O) richterite forsteritic olivine aluminum-poor (<l wt% Al2O3), ...

Primary mineralogy is highly variable, but may include natrolite, sodalite, sovite, apatite, magnetite, barite, fluorite, ancylite group minerals, and other rare, peculiar minerals not found in more normal igneous rocks. Recognition of carbonatites may be difficult, especially as their mineralogy and texture may not differ much from marble save for the presence of igneous minerals. They may also be sources of mica or vermiculite. Natrocarbonatite is made up largely of two minerals, nyerereite (named after Julius Nyerere, the fi ...

Granite primarily consists of orthoclase and plagioclase feldspars, quartz, hornblende, biotite, muscovite and minor accessory minerals such as magnetite, garnet, zircon and apatite. Rarely, a pyroxene is present. Granite is classified according to the QAPF diagram for coarse grained plutonic rocks (granitoids) and is named according to the percentage of Quartz, Alkali feldspar (orthoclase) and Plagioclase Feldspar on the A-Q-P half of the diagram. Highly peralkaline forms of granite which are silica undersaturated may have a feldspathoid such as nepheline, and are classified on the A-F-P hal ...

In gemology, aventurescence (sometimes called aventurization) is an optical reflectance effect seen in certain gems. The effect amounts to a metallic glitter, arising from minute, preferentially oriented mineral platelets within the material. These platelets are so numerous that they also influence the material's body colour. In aventurine quartz (actually a type of quartzite) chrome-bearing fuchsite makes for a green ...

In mineralogy, shape and size give rise to descriptive terms applied to the typical appearance, or habit of crystals. The many terms used by mineralogists to describe crystal habits are useful in communicating what specimens of a particular mineral often look like. Recognising numerous habits helps a mineralogist to identify a large number of minerals. Some habits are distinctive of certain minerals, although most minerals exhibit many differing habits which are influenced by certain factors. Crystal habit may mislead the inexperienced as a ...

This is a list of academic disciplines (and academic fields). An academic discipline is a branch of knowledge which is formally taught, either at the university, or via some other such method.

Each discipline usually has several sub-disciplines or branch ...

In gemology, chatoyancy is an optical reflectance effect seen in certain gemstones. Coined from the French, meaning "cat's eye," chatoyancy arises either from the fibrous structure of a material, as in tiger eye quartz, or from fibrous inclusions or cavities within the stone, as in cat's eye chrysoberyl. The effect can be likened to the sheen off a spool of silk; the mobile, wavering reflection always being perpendicular to the direction of the fibres. For a gemstone to show this effect it must be cut en cabochon, with the fibers or fibrous struc ...

Earth science (also known as geoscience, the geosciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth science. The major historic disciplines use physics, geography, mathematics, chemistry, and biology to build a quantitative understanding of the principal areas or spheres of the Earth system: Including:

Oxford University Museum of Natural History - The 1860 evolution debate. A significant debate in the history of evolutionary biology took place in the museum in 1860 at a meeting of the British Association for the Advancement of Science. Representatives of the Church and science debated the subject of evolution, and the event is often viewed as symbolising the defeat of theological views of creation. However, there are few eye-witness a ...

The museum was formally founded on 10 June 1793, during the French Revolution. Its origins lie, however, in the Jardin royal des plantes médicinales (Royal Medicinal Plant Garden) created by King Louis XIII in 1635, which was directed and run by the royal physicians. The royal proclamation of the boy-king Louis XV on 31 March 1718, however, removed the medical function, enabling the garden—which became known simply as the See also:

The specimen of Brachiosaurus brancai¹ in the central exhibit hall is the largest mounted dinosaur skeleton in the world. It is composed of fossilized bones recovered by the German paleontologist Werner Janensch from the fossil-rich Tendaguru beds of Tanzania between 1909 and 1913. The remains are primarily from one gigantic animal, except for a few tail bones (caudal vertebrae) which belong ...
