The composition range of Cr-sp in the two types of chromite deposit are distictly different.

两类矿床中副矿物铬尖晶石的成分从二辉橄榄岩至纯橄岩均显示出富Cr贫AL的演化趋势。

With the help of infrared spectroscopy, it is known that the linkage between dodecylamine and sodium oleate and diaspore, kaolinite, illite and pyrophyllite is fundamentally electrostatic forces, which contributes to physical adsorption. The adsorption is related with surface electric property of minerals. The effect of chemical composition of diaspores on their electrokinetics was investigated.

对于一水硬铝石矿物来说，三个主要晶面（010）、（100）和（001）上的单位面积断裂键数有如下关系：〓；一水硬铝石表面吸附的动力学模拟可以说明，一水硬铝石的（010）晶面、（100）晶面和（001）晶面，分别吸附几种捕收剂离子的吸附能大小为：（010）晶面的吸附能＞（100）晶面的吸附能＞（001）晶面的吸附能；分别吸附这些药剂离子的单位面积吸附量〓的大小顺序为：（010）晶面＞（100）晶面＞（001）晶面。

Characteristics of these two kinds of spinels not only indicate that the whole terrain underwent granulite facies metamorphism but also provide direct mineralogical evidence for the argument that Yushugou ophiolite suite of granulite facies lies in an environment of oceanic basin.

这两类尖晶石的特征一方面说明该地体遭受了麻粒岩相的变质作用改造，另一方面也提供了榆树沟麻粒岩相蛇绿岩套属洋盆构造环境的直接矿物学证据。

According to the phase relationship in the reaction system felsic melt＋ small amount of peridotite, we suggest that assimilation of the mantle clinopyroxene ＋ olivine ＋ spinel as well as the fractional crystallization of sodic amphibole and clinopyroxene is an important process which modifies the composition of adakites and cause the Na depletion in adakites..

根据长英质熔体与橄榄岩反应体系的相关系，我们认为，地幔单斜辉石、橄榄石、尖晶石的混染作用以及钠质角闪石和斜方辉石的分离结晶作用，是改变埃达克熔体组成并导致其Na亏损的一个重要的过程。

Is a company specializing in operating high-end new construction materials ----- Microcrystalline stone of the modern high-tech enterprises.

广东强兴公司是一家专业经营新型高档建筑材料-----微晶石的现代高科技企业。

The micro spar's coloration is take the metal oxide compound as the coloring agent, becomes after the high temperature agglutination, therefore, will not fade, and the luster will be bright.

微晶石的着色是以金属氧化物为着色剂，经高温烧结而成的，因此，不会褪色，且色泽鲜艳。

The color of the spinels are related to Al,Mg and Cr,Fe contents.

尖晶石的颜色与Al、Mg、Cr、Fe含量有关。

Spinel is a compound of magnesia and alumina(Al2O3) and is thus a magnesium aluminate(MgAl2O4), found as accessories in igneous rocks, in metamorphosed aluminous schists, in contact metamorphosed limestones and sometimes in high temperature iore veins.

尖晶石主要成分是氧化镁和氧化铝，结晶习性是等轴晶系漂亮的正八面体。镁被铁置换就是铁尖晶石，被锌置换就是锌尖晶石，铁完全置换镁形成磁铁矿，铬置换铁尖晶石形成铬铁矿，这些类质同相的等轴晶系都是八面体结晶的尖晶石族矿物。
