Olivine occurs in both mafic and ultramafic igneous rocks and as a primary mineral in certain metamorphic rocks. Nebular history of amoeboid olivine aggregates 561 Fig. Britannica Kids Holiday Bundle! The melts, in the form of 2-mm-diameter spherules, were subjected to cooling rates of 220-460 or 1300-3700°C/hr and either held at ~ 1460°C for up to 90 minutes or continuously cooled to ~ 600°C. It is also the stone for the Zodiac sign of Libra. Hoefen, T.M., et al. At the high temperatures and pressures found at depth within the Earth the olivine structure is no longer stable. Northwest Africa (NWA) 1068 is one of the few olivine-phyric shergottites (e.g., NWA 1068, Larkman Nunatak [LAR] 06319, and Roberts Massif [RBT] 04262) that is not depleted in light rare earth elements (LREE). It is widely used as a gemstone and possess many useful properties. Olivine was also obtained from the construction site of the hydro power stations in Tafjord. Three haplochondritic melts were experimentally examined to investigate thermal parameters in the pre-accretionary chondrule environment. World authority on igneous petrology. Girl. Olivine. Multi-stage magmatic history of olivine–leucite lamproite dykes from Banganapalle, Dharwar craton, India: evidence from compositional zoning of spinel Drought-resistant Scots pine is one of the few trees that thrive on olivine rock. Magnesium iron silicate solid solution series mineral. Fig. The pressure at which these phase transitions occur depends on temperature and iron content. Any of a group of olive green magnesium-iron silicate minerals that crystallize in the orthorhombic system.. olivine synonyms: chrysolite. However, in calcic olivines like monticellite, calcium preferentially enters the M2 site and magnesium occupies the M1 site. It is rare and found on dry olivine ridges in the fjord districts of Sunnmøre and Nordfjord. Olivine phenocrysts have large unzoned cores surrounded by narrow normally zoned rims (Renner et al., 1994). These meteorites are thought to have originated from the mantle of a rocky planet that used to occupy an orbit between Mars and Jupiter - or they might be from an asteroid that was large enough to have developed a differentiated internal structure consisting of a rock mantle and a metallic core. In magnesium-iron olivines there is no M1 or M2 site preference for magnesium or ferric iron. [32], A worldwide search is on for cheap processes to sequester CO2 by mineral reactions, called enhanced weathering. Dunite and other peridotite rocks are major constituents of the Earth's mantle above a depth of about 400 kilometers. In addition to these magnesium and ferrous iron end-members, the olivine group contains manganese (tephroite), calcium-manganese (glaucochroite), calcium-magnesium (monticellite), and calcium-iron (kirschsteinite) end-members (Table). All the CO2 that is produced by burning one liter of oil can be sequestered by less than one liter of olivine. History . Advertisement Origin of Olivine Name. Olivine possesses a number of advantages compared to silica, the most important being a lower and more uniform thermal expansion and inertness towards certain difficult alloys, notably manganese steels. Famous People Named Olivine. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. [24][25] The presence of iddingsite on Mars would suggest that liquid water once existed there, and might enable scientists to determine when there was last liquid water on the planet. Dynamic crystallization experiments were performed on a liquid having the bulk composition of olivine-phyric shergottite Yamato 980459, to constrain the igneous thermal history of this meteorite. Because it is thought to be the most abundant mineral in Earth's mantle at shallower depths, the properties of olivine have a dominant influence upon the rheology of that part of Earth and hence upon the solid flow that drives plate tectonics. It contains olivine crystals as magnesian as Fo 77 and is a major source of information to constrain the composition of the parental melt, the composition and depth of the mantle source, and the cooling and crystallization history of one of the younger magmatic events on Mars (∼180 Ma). Olivine gives its name to the group of minerals with a related structure (the olivine group)—which includes tephroite (Mn2SiO4), monticellite (CaMgSiO4), larnite (Ca2SiO4) and kirschsteinite (CaFeSiO4) (commonly also spelled kirschteinite [9]). Please select which sections you would like to print: Corrections? Olivine has been identified in a large number of stony and stony-iron meteorites. Gender of Olivine. Olivine is one of the most common mineral found on the earth. "University of Minnesota's Mineral Pages: Olivine", St. John's Island peridot information and history, "Olivine hydration in the deep upper mantle: Effects of temperature and silica activity", "Discovery of Olivine in the Nili Fossae Region of Mars". Olivine's crystal structure incorporates aspects of the orthorhombic P Bravais lattice, which arise from each silica (SiO4) unit being joined by metal divalent cations with each oxygen in SiO4 bound to three metal ions. This specimen is approximately 3 … Mg-rich olivine is stable to pressures equivalent to a depth of about 410 km (250 mi) within Earth. O3 lies in a general position. The characteristic red color is reflected in several local names with "red" such as Raudbergvik (Red rock bay) or Raudnakken (Red ridge). Information and translations of olivine in the most comprehensive dictionary definitions resource on … Plastic deformation in olivine of the chondrites, as evidenced by irregular kink bands and undulatory extinction, has taken place predominantly on the system T = {110}, (100), t = [001], the low temperature and/or high strain‐rate systems in static experiments. Define olivine. [19] Comet-like (magnesium-rich) olivine has also been detected in the planetesimal belt around the star Beta Pictoris.[20]. English. The layers consist of octahedrons cross-linked by independent SiO4 tetrahedrons. Compositions of olivine are commonly expressed as molar percentages of forsterite (Fo) and fayalite (Fa) (e.g., Fo70Fa30). olivine - WordReference English dictionary, questions, discussion and forums. Fe-rich olivine fayalite is relatively much less common, but it occurs in igneous rocks in small amounts in rare granites and rhyolites, and extremely Fe-rich olivine can exist stably with quartz and tridymite. The name forsterite is restricted to those species with no more than 10 percent iron substituting for magnesium; fayalite (from Fayal Island in the Azores, where it was believed to occur in a local volcanic rock but probably was obtained from slag brought to the island as ship’s ballast) is restricted to species with no more than 10 percent magnesium substituting for iron. Olivine is classified as a nesosilicate which has isolated SiO4 tetrahedrons bound to each other only by ionic bonds from interstitial cations. Olivine also occurs in high-temperature metamorphic rocks, lunar basalts, and some meteorites. Fayalite is soluble in all proportions with ash-gray tephroite (from Greek tephros, “ashen”), pure manganese silicate (Mn2SiO4); the intermediate in the series is knebelite (FeMnSiO4). I make perfume because I love it. In fact, the Egyptians called it the “gem of the sun.” Some believed that it protected its owner from “terrors of the night,” especially when it was set in gold. INTRODUCTION. Olivine has a number of other historical uses as gemstones, usually called peridot and chrysolite, and industrially for metal working processes. 35 T.29N R.7E). Apart from ferrous iron, the crystalline structure of the olivines is also capable of accommodating relatively small amounts of ferric iron; dendrites (small branching crystals) of magnetite or chromite found oriented with respect to some crystallographic direction within such olivines may be attributed to exsolution. Gender of Olivine. Most of the naturally occurring olivines are intermediate in composition to these two end-members and have the general formula (Mg, Fe)2SiO4. Olivine … It alters into iddingsite (a combination of clay minerals, iron oxides and ferrihydrites) readily in the presence of water. Olivine Name Meaning and History. The continuity in the forsterite-fayalite series has been verified experimentally. Forsterite's melting temperature is unusually high at atmospheric pressure, almost 1,900 °C (3,450 °F), while fayalite's is much lower — about 1,200 °C (2,190 °F). Minor elements such as aluminum, nickel, chromium, and boron can substitute in olivine. Get exclusive access to content from our 1768 First Edition with your subscription. — Olivine is an accessory minerals in quartz syenite exposed at the old Technical Institute in Wausau (NE NE Sec. [23] Artificially increasing the weathering rate of olivine, e.g. A pretty light green stone. The name olivine derives from the unusual yellow-green to deep bottle-green colour of the magnesium-iron olivine series. Olivine rock is usually harder than surrounding rock and stands out as distinct ridges in the terrain. The olive was native to Asia Minor and spread from Iran, Syria and Palestine to the rest of the Mediterranean basin 6,000 years ago. Olivines are an important rock-forming mineral group. Magnesium-rich olivines are abundant in low-silica mafic and ultramafic igneous rocks and are believed to be the most abundant constituent of the Earth’s upper mantle. Moreover, because olivine is so abundant, more water may be dissolved in olivine of the mantle than is contained in Earth's oceans.[12]. In Finland, olivine is marketed as an ideal rock for sauna stoves because of its comparatively high density and resistance to weathering under repeated heating and cooling. It ranges in colour from chartreuse green to pale olive.In its gem form, it is called peridot.. Dunite is a rock of 90%+ olivine. Olivine in basalt: Lherzolite (a variety of peridotite) nodules in a xenolith collected from a basalt flow at Peridot Mesa, Arizona. Trusted by millions of genealogists since 2003. The olivinecrystals in most basalts are imperf… Omissions? Thus it is a type of nesosilicate or orthosilicate. [31], Kallskaret near Tafjord is a nature reserve with olivine. Trusted information source for millions of people worldwide. Research output: Contribution to journal › Article › peer-review. Fayalite is the iron rich member with a pure formula of Fe 2 SiO 4. For example, Fo70Fa30 denotes a composition of olivine that is 70 percent forsterite. Olivine (or chrysolite) is a silicate mineral made of magnesium iron silicate with the formula (Mg,Fe)2SiO4.. Kimberlite, as illustrated in Figs 1 and 2, is a rock dominated by olivine.Most kimberlites are highly altered and their primary textures are poorly preserved, but rare examples, such as the sample from the Kangamiut region of Greenland shown in Fig. Meaning of olivine. 22 T.29N R.6E (Sood, Myers and Berlin, 1980). Olivine is named for its typically olive-green color, thought to be a result of traces of nickel, though it may alter to a reddish color from the oxidation of iron. Below depths of about 410 km (250 mi) olivine undergoes an exothermic phase transition to the sorosilicate, wadsleyite and, at about 520 km (320 mi) depth, wadsleyite transforms exothermically into ringwoodite, which has the spinel structure. What Does Olivine Mean and History? Trusted information source for millions of people worldwide. 2003. In the midst of the Hundred Years' War, the young King Henry V … The primary component of the Earth's upper mantle, it is a common mineral in Earth's subsurface, but weathers quickly on the surface. ‘Here, olivine (peridot when gemmy) grains or anhedral crystals weather out of basaltic lava.’ ‘This flow consists of about 30 percent plagioclase, clinopyroxene, and olivine, as small phenocrysts.’ ‘They typically comprise early olivine and plagioclase, ophitically enclosed by augite, with opaque oxides and apatite.’ Analysis of Olivine. Timetemperature paths for experiments listed in - "Igneous cooling history of olivine-phyric shergottite Yamato 980459 constrained by dynamic crystallization experiments" — Olivine occurs in small amounts with nepheline, perthite, biotite, zircon and other minerals in the old zircon mine in the SE SE Sec. Geology of Wisconsin: Survey of 1873-1879 by Wisconsin Chief Geologist (1880) Thus it is a type of nesosilicate or orthosilicate. The most abundant olivines occur in the system from forsterite (Mg2SiO4) to fayalite (Fe2SiO4). Here is another pale-green sample typical of beginning geology labs. Users of this name Gentle , Rich and Humble , Stubborn , Innovative , Happy , High ability of Persuasion. There are two symmetrically nonequivalent octahedral sites, M1 and M2. Indian, Hindu. The ratio of magnesium to iron varies between the two endmembers of the solid solution series: forsterite (Mg-endmember: Mg2SiO4) and fayalite (Fe-endmember: Fe2SiO4). All olivines crystallize in the orthorhombic crystal system. Most people chose this as the best definition of olivine: A mineral silicate of iro... See the dictionary meaning, pronunciation, and sentence examples. For the last 20+ years, I have been helping women look, feel, and smell beautiful.

In addition to the forsterite-fayalite series, other complete solid-solution series exist among the various olivine minerals. Type-1 olivine is rich in Ca and Mg, and the zoning profile of type-1 forms a slightly more Fe-rich trend than the maximum fractionation trend in … Olivine Family History. Send us will publish it for you. Thus, it is a type of nesosilicate or orthosilicate. Gem-quality forsterite olivine is known as peridot. Olivine is a mineral with a distinct green color and granular-shaped crystals. Melting temperature varies smoothly between the two endmembers, as do other properties. Core compositions range from Fo … See the birthstone tables for additional references to this stone. The two minerals form a series where the iron and magnesium are substituted for each other without much effect on the crystal structure. Olivine-rich rocks mainly from the Archaean are the source of multi-billion dollar nickel mining industry. Olivine pine forest is unique to Norway. Increasing the iron content decreases the pressure of the phase transition and narrows the wadsleyite stability field. At a depth of about 660 km (410 mi), ringwoodite decomposes into silicate perovskite ((Mg,Fe)SiO3) and ferropericlase ((Mg,Fe)O) in an endothermic reaction. In an alternative view, the atomic structure can be described as a hexagonal, close-packed array of oxygen ions with half of the octahedral sites occupied with magnesium or iron ions and one-eighth of the tetrahedral sites occupied by silicon ions. The olivines are a class of common silicate minerals named for their greenish or olive color. A rock consisting of pure olivine is called dunite. Girl. Mg-rich olivine has also been discovered in meteorites,[13] on the Moon[14] and Mars,[15][16] falling into infant stars,[17] as well as on asteroid 25143 Itokawa.

As the whole of the Earths mantle is composed of more than 80% olivine or its high pressure equivilent, it is the most common mineral knowns. Translucent olivine is sometimes used as a gemstone called peridot (péridot, the French word for olivine). The presence of relatively large amounts of ferric oxide in the analyses of olivines, however, clearly indicates either an advanced state of oxidation or the mechanical inclusion of co-precipitating magnetite upon crystallization from the magma. — Olivine is an accessory mineral in the pegmatitic nepheline syenite exposed in cuts along County Highway U, 0.5 miles east of the little Rib River in the SW SW Sec. The structure of olivine can be viewed as a layered closest-packed oxygen network, with silicon ions occupying some of the tetrahedral voids and the calcium, ferrous iron, and magnesium cations occupying some of the octahedral voids (Figure 2). For this reason, Olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation. [citation needed], The aluminium foundry industry uses olivine sand to cast objects in aluminium. This 146.10-carat peridot is in the collection of the Natural History Museum in London Peridot has always been associated with light. Updates? Figure 2: Portion of the idealized structure of olivine projected perpendicular to the. The metamorphism of impure dolomite or other sedimentary rocks with high magnesium and low silica content also produces Mg-rich olivine, or forsterite. [26], Norway is the main source of olivine in Europe, particularly in an area stretching from Åheim to Tafjord, and from Hornindal to Flemsøy in the Sunnmøre district. At about 0.8 mole fraction fayalite, olivine transforms directly to ringwoodite over the pressure range 10.0 to 11.5 GPa (99,000–113,000 atm). The mineral olivine ( /ˈɒlɪˌviːn/) is a magnesium iron silicate with the formula (Mg2+, Fe2+)2SiO4. Tephroite and knebelite come from manganese and iron ore deposits, from metamorphosed manganese-rich sedimentary rocks, and from slags. The reaction is exothermic but slow. Analysis of Olivine. Recently, olivine has been used as an alternative to silica sand and… Olivine - Olivine - Meteorites and the Earth’s mantle: In meteorites, the olivine is usually a forsteritic variety containing only Fa15 to Fa30. Olivines are an important rock-forming mineral group. [36] Olivine is also used to tap blast furnaces in the steel industry, acting as a plug, removed in each steel run. Olivine - Olivine - Mineralogical characteristics: The specific gravity and hardness of the olivines are listed in the Table. Peridot is the official birthstone for the month of August as adopted by the American National Association of Jewelers in 1912. Our research results for the name of Olivine is fit … The composition of most olivines can be represented in the system Ca2SiO4-Mg2SiO4-Fe2SiO4 (Figure 1). All Free. Manganese (Mn) and nickel (Ni) commonly are the additional elements present in highest concentrations. The olivine phenocrysts can be divided into three types on the basis of chemical composition, zoning profile and occurrence. This 146.10-carat peridot is in the collection of the Natural History Museum in London Peridot has always been associated with light. These phase transitions lead to a discontinuous increase in the density of the Earth's mantle that can be observed by seismic methods. Ultramafic rocks such as peridotite and dunite can be residues left after extraction of magmas, and typically they are more enriched in olivine after extraction of partial melts. These olivine – spinel phase transitions affect the mechanical properties of the whole mantle, which in turn determine the convective flow processes that drive plate tectonics and thus much of the geological history Earth. ]: Eos, Transactions, American Geophysical Union, v. 57, p. 345. Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, adoption, and even physical characteristics (like red hair). We have collected some of the best resources from across the web to do research on Olivine history, Olivine ancestory, and Olivine family connections. "Discovery of Olivine in the Nili Fossae Region of Mars". Less water means less gas (steam) to vent from the mold as metal is poured into the mold.[37]. The use of peridot in jewelry and other applications dates as far back as the ancient Egyptians from around 1500 B.C., making it one of the oldest gemstones. Founded in 1979, from its beginning as a small retail business located along Beach Road has today expanded and became leading Singapore player in the international trading of consumer electronic products. It is one of the first minerals to cool and crystallize from magma. Would you like to add a information. These xenoliths often contain crystals of olivine with a color and clarity that is suitable for use as a peridot gemstone. Olivine, any member of a group of common magnesium, iron silicate minerals. by dispersing fine-grained olivine on beaches, has been proposed as a cheap way to sequester CO2.
