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。

It indicates that electrical conduction ofα- andβ-phases is not caused by transport of protons bounded at Mg tetrahedral position.

这表明镁橄榄石的导电可能不是由镁离子位置上的质子移动引起的。

The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.

康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同，认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成，与地幔橄榄岩也不存在成因联系，认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体，但两者可能均是由地幔深部被地幔柱带到上部。

The main minerals in mantle enclaves and volcanic rocks of different periods are olivine clinopyroxene, enstenite, spinel, plagioclase and alkali feldspar.

幔源包体及不同期次火山岩的主要矿物是橄榄石、单斜辉石、斜方辉石、尖晶石、斜长石、碱性长石。

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。

The analysis of the chemical composition of mineral inclusions including olivine, garnet, clinopyroxene, and chromite from Mengyin and Fuxian diamonds, reveals that the major elements of mineral inclusions in diamond show characters with high depletion in basaltic composition.

对山东蒙阴、辽宁复县两地金刚石中包裹体矿物包括橄榄石、石榴石、单斜辉石和铬铁矿的化学成分进行了深入分析，金刚石包裹体矿物的主量元素显示华北地台至少在古生代金伯利岩侵位时具高度亏损玄武质的难熔克拉通岩石圈地幔特征。

The metasomatism resulted in decreasing content of orthopyroxene, increasing contents of clinopyroxene and olivine in peridotite, and the transformation from harzburgites to wehrlites.

这种交代导致橄榄岩中斜方辉石逐渐减少，单斜辉石和橄榄石逐渐增加，从而使方辉橄榄岩渐变成易剥橄榄岩。

In this paper, the distribution of clinopyroxene, orthopyroxene, olivine, plagioclase and ilmenite on lunar surface was mapped based on Hapke radioactive transfer model and linear unmixing of spectra using Clementine UV/VIS/NIR data. The result is compared with the results obtained by previous researchers and Apollo sample analysis, and the problems existing in mineral abundance mapping are analyzed preliminarily.

基于Hapke模型与光谱线性分解的矿物提取方法，利用Clementine UV/VIS/NIR数据提取月表单斜辉石、斜方辉石、橄榄石、斜长石及钛铁矿等5类主要矿物的体积百分含量分布，并基于阿波罗月岩矿物分析数据对提取结果进行评价，对方法和提取结果中存在的问题进行分析，提出了进一步改进的措施。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
