olivine    音标拼音: ['ɑləv,in]
n. 橄榄石,黄绿

olivine
n 1: a mineral consisting of magnesium iron silicate; a source
of magnesium

Olivine \Ol"i*vine\, n. [Cf. F. olivine.] (Min.)
A common name of the yellowish green mineral chrysolite, esp.
the variety found in eruptive rocks. It is a silicate of
magnesium and iron ({(Mg,Fe)SiO4}).
[1913 Webster PJC]


Chrysolite \Chrys"o*lite\, n. [L. chrysolithos, Gr. ?; chryso`s
gold ? stone: cf. F. chrysolithe.] (Min.)
A mineral, composed of silica, magnesia, and iron, of a
yellow to green color. It is common in certain volcanic
rocks; -- called also {olivine} and {peridot}. Sometimes used
as a gem. The name was also early used for yellow varieties
of tourmaline and topaz.
[1913 Webster]

  • Olivine - an overview | ScienceDirect Topics
    Introduction Olivine 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
  • Olivine formation processes and fluid pathways in subducted . . .
    These data are used to distinguish in-situ olivine and fluid production during the antigorite+brucite reaction from fluid migration and olivine crystallization during reactive fluid flow

  • Olivine chemistry reveals compositional source heterogeneities within a . . .
    However, a signal of a more pyroxenitic mantle lithology is clearly visible in olivine from the South Iceland Volcanic Zone, which represents the southward propagation of the Eastern Rift Zone, while olivine from Tertiary lavas suggests a mixed peridotite-pyroxenite source composition

  • Olivine dissolution rates: A critical review - ScienceDirect
    A survey of the literature suggests that the major factors influencing forsteritic olivine dissolution rates are 1) pH, 2) water activity, 3) temperature, and 4) mineral-fluid interfacial surface area Evidence suggests that the effects of aqueous inorganic and organic species are relatively limited, and may be attributed at least in part to their influence on aqueous solution pH Moreover

    Olivine is a silicate mineral primarily composed of magnesium and iron with the chemical formula of (Mg,Fe) 2 SiO 4 This mineral is typically found in mafic and ultramafic magmatic rocks that are formed deep in the upper mantle (Smyth et al , 2006) The unique structure of olivine comprises a dense hexagonal sphere of oxygen atoms, with smaller tetrahedral gaps containing silicon and

    Olivine is an abundant constituent of the lunar mantle that constrains models of lunar origin and evolution (e g , Snyder et al , 1992, Elkins-Tanton et al , 2011) Remote detection of surface olivine is a challenge, in part because of its rarity, as evidenced by the almost complete absence of large-scale samples (e g , dunite clasts) in the lunar sample collection, and also because, in the
