Get PriceAlthough olivine only contains iron in reduced form Fe II no strain of nFeO microorganism has ever been reported to have the capacity to use this mineral as a source of energy Such a finding would be invaluable for the study of olivine bioweathering; the identification of biosignatures and microfossils; determination of whether life and
Get PriceDuring the slow cooling of a magma crystals of olivine may form and then settle to the bottom of the magma chamber because of their relatively high density This concentrated accumulation of olivine can result in the formation of olivine rich rocks such as dunite in the lower parts of a magma chamber

Get PriceOlivine has a very high crystallization temperature making it one of the first minerals to crystallize from magma Silica within the molten rock will form olivine while it is still liquid at temperatures over 2 000 degrees Fahrenheit The remaining silica will form a range of different other minerals as the magma cools
Get PriceOlivine that has a beautiful color is used as a material of jewelry The most famous ones have a green color The jewelry name is Peridot and it is known as the birthstone of August It has high transparency and a luxurious mood The price can vary depending on its color size and scratches on the surface A big Olivine is rare and it will
Get PriceOlivine occurs in both mafic and ultramafic igneous rocks and as a primary mineral in certain metamorphic rocks Olivine and high pressure structural variants constitute over 50% of the Earth s upper mantle and olivine is one of the Earth s most common minerals by volume Properties occurrences alteration and uses of Olivine Group of Minerals
Get PriceWhat does Olivine mean O livine as a girls name is of Latin derivation and the name Olivine means olive tree Olivine is an alternate form of Olivia Latin STARTS WITH Ol ASSOCIATED WITH olive tree Variations ALTERNATIVE FORMS VIA OLIVIA Alivia Livie Olevia Oliffe Oliva Olive Olivea Oliveea Olivet Olivette Olivija Olivya
Get PriceOlivine is an important rock forming mineral and is common in mafic igneous rocks such as peridotite gabbro and basalt along with pyroxene and plagioclase The ultramafic rock dunite consists almost entirely of olivine and is the result of the fractional crystallization of peridotite composition melts to form cumulate olivine
Get PriceSome variations of optical properties observed in natural olivine crystals probably result from small but varying replacements of magnesium and iron by calcium and manganese and of silicon by titanium chromium and ferric iron Crystal habit and form The magnesium iron olivines occur most commonly as compact or granular masses
Get PriceWhen does the crystal structure of olivine change Olivine tolerates well pressures in the crust and in the upper mantle but at 350 km depth its crystal structure starts to break down The composition remains but it takes a new and more compact form It is not technically olivine anymore because minerals have a definite crystal structure
Get PriceOlivine is the name given to a group of minerals that contribute to rock formation They are usually found in igneous rocks such as peridotite gabbro dunite diabase and basalt Many people are familiar with olivine due to it being the mineral form of the popular gem peridot
Get PricePrimary olivine branches form rapidly <0 5 h for −Δ T = 40 60°C after reaching the final temperature Figure 3G and an outer faceted shell forms after a few minutes to a few hours depending on the degree of undercooling Figures 3C G
Get PriceMost olivine found at Earth s surface is in dark colored igneous rocks It usually crystallizes in the presence of plagioclase and pyroxene to form gabbro or basalt These types of rocks are most common at divergent plate boundaries and at hot spots within the centers of tectonic plates
Get PriceOlivine is an important rock forming mineral and occurs in mafic igneous rocks such as peridotite gabbro and basalt along with pyroxene and plagioclase The ultramafic rock dunite consists almost entirely of olivine and is the result of the fractional crystallisation of peridotite composition melts to form cumulate olivine

Get PriceThe process is called weathering and it is the natural chemical breakdown of rock that occurs when it is exposed to atmospheric gases In this case we are looking specifically at the rock olivine when it comes in contact with ocean water and the CO2 dissolved in it
Get PriceOlivine has general formula Mg Fe 2 SiO 4 Most natural olivines contain only minor other components Identification Olivine is in many ways similar to clinopyroxene The keys to identifying olivine are its high birefringence lack of cleavage but often having fractures and alteration Important properties
Get PriceTypically olivine erupts with the calm oozing of basalt lava on Hawaii locking it away within the rock fabric However in this instance the sudden ejection of lava into the air rapidly cools
Get PriceOlivine is one of the most common minerals in the earth and is a major rock forming mineral Despite this good specimens and large crystals are uncommon and sought after Only few localities yield large examples of this mineral although small and microscopic grains are found worldwide
