镁橄榄石

The formation and evolution of magma have experienced three stages:① thermal fluid led to higher partial melting of lithosphere mantle and then formed hypoalkaline basalt with saturated initial sulfur when ascending asthenosphere contacted with the lithosphere mantle;② the initial magma intruded into the lower crust to form magma chamber, the crystallization of magma produced stratiform-like cumulate, including olivine, hypersthene, augite, magnetite, and then formed residual gabbroic magma with the participance of crustal material;③ the residual magma and ore-bearing cumulate intruded upward successively to shape original mafic complex rocks in Wuxing when the magma chamber cracked.

岩浆形成与演化经历了3个阶段：①上升的软流圈与岩石圈地幔接触，热流体作用导致岩石圈地幔发生高度部分熔融，形成初始硫饱和的次碱性玄武岩；②初始岩浆上侵，在下地壳形成岩浆房，岩浆结晶作用形成以似层状橄榄石、紫苏辉石、普通辉石和磁铁矿等为主的堆晶岩，在地壳物质的参与下形成残余辉长质岩浆；③岩浆房破裂，残余岩浆和含有熔体(0%)的堆晶岩相先后上侵形成五星原始镁铁质杂岩。

It is made of Magnesium and Iron Silicate, and it is a member of the Chrysolite mineral family.

它是由镁，矽铁，它是一个成员橄榄石矿物家庭。

A dense igneous rock that consists mainly of olivine and is a source of magnesium.

纯橄榄岩一种密度大的大成岩，主要由橄榄石组成，是镁的一种来源

Since olivine is silica-unsaturated, quartz and olivine never coexist in the same rock. Therefore, in mantle peridotite and other ultramafic rocks, primary quartz can never be found.

由于石英和非饱和SiO_2的橄榄石不能共生，因此在地幔橄榄岩和超镁铁岩中不存在原生石英。

There are two kinds of spinels in a granulite terrain of Yushujgou, South Tianshan Mountain. One occurs in the intermediate and basic granulite units and is characterized by enriched Al and poor Cr, belonging to Al_spinel. In thin sections it shows dark green color and subhedral to anhedral form, and coexists with other metamorphic minerals, suggesting a neogenic metamorphic mineral of granulite facies. The other occurs in the adjacent ultramafic rock unit, belonging to Cr_spinel. In thin sections, it is dark brown in color and is scattered among olivine, clinopyroxene and orthopyroxene as irregular grains, indicating a stable residual mineral in the process of granulite facies metamorphism.

新疆榆树沟麻粒岩地体中发育两类尖晶石：一类见于中、基性麻粒岩体中，其化学成分富 Al贫 Cr ，属铝尖晶石，镜下为深绿色，呈半自形至他形粒状，与其它变质矿物共生，表现为麻粒岩相的新生变质矿物；另一类发育在空间上与麻粒岩体紧密相邻的超镁铁质岩体中，为铬尖晶石，镜下为深褐红色，呈不规则粒状分布于橄榄石、斜方辉石和单斜辉石之间，为麻粒岩相变质过程中稳定的残余矿物。

Pair of sample that add Al and Si fall in two kinds of temperature, magnesian olivine (Mg2SiO4) and pointed spar (MgAl2O4) shows similar action.

在两种温度下对添加Al和Si的试样，镁橄榄石(Mg2SiO4)和尖晶石(MgAl2O4)显示出相似的功能。

To enrich the outlook of glass-ceramics and improve its competitive power, an ingredients schedule with fly-ash solid residue as main raw materials, which contained fluorine after some valuable materials were obtained, was put forward based on theoretic analysis, making use of the characteristics of silicofluoride as crystal nucleating agents.

为丰富微晶玻璃外观色泽，提高产品竞争力，利用氟硅酸盐在微晶玻璃制备中可作成核剂的特性，经过理论分析确定以粉煤灰提取有价成分后的含氟固体残渣为主要原料生产镁橄榄石微晶玻璃的配料。

The gemological characteristics of lemon-yellow serpentine jade are studied by the conventional gemology instrument and the polarizing microscope; the Fourier transform infrared spectroscopy, ultraviolet-visible light absorption spectra, X-ray power diffraction and electron probe quantitative analysis have also been used to study the lemon-yellow serpentine jade.

通过常规的宝石学仪器和偏光显微镜来研究柠檬黄色的蛇纹石玉的宝石学性质，进一步用Fourier变换红外光谱、紫外－可见吸收光谱、X射线粉晶衍射和电子探针定量分析对柠檬黄色的蛇纹石玉进行研究，结果表明：这种柠檬黄色的蛇纹石玉主要成分为利蛇纹石，含有少量的纤蛇纹石、水镁石、橄榄石、菱镁矿等。

Some characteristic ratios suggest the picrites and ankaramites were derived from asthenospheric mantle, and high Os/Ir ratios reflect the involvements of pelagic sediments. Pd/Ir versus Ni/Cu diagram implies that the picrites and ankaramites were not primary magmas, but MgO-high basalts with excess olivines, whereas Pd versus Cu diagram suggests a S-undersaturated primary magma.

一些铂族元素的特征比值指示了苦橄岩和富辉玄武岩起源于软流圈地幔，而高的w/w比值则暗示了源区中有深海沉积物的加入。w/w-w/w图解说明本区的苦橄岩不是原始岩浆，而是原始的高镁玄武岩中有过剩橄榄石的加入，而w-w图解则说明原始岩浆硫不饱和。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
