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。

And a few stacks are evidently curved, which shows the compression parallel to the bedding. According to the relation-ship between stack, bedding and hydraulic fractured-filled quartz veinlet, the very low metamorphism is regarded as the product before the regional deformation structure-thermal event.

根据堆垛集合体、层理及早世代水力破裂充填石英微细脉体间关系，认为极低级变质作用是区域变形构造热事件之前的产物：变质温度在 15 5～ 35 0°C之间，变质级、地层时代及岩层在地层柱中的位置渐趋一致，与区域变形强度缺乏谐调关系。

The Sm-Nd isochron age (1182±50Ma) of Kangshan metamorphic complex has first been presented in the paper, which deny the tranditional point that the complex is Archean Taihua group. It's suggested that the plagioclase-amphibolite originates from subcon tinantal lithospheric mantal, assimilating and hybridizing minor crustal materials.

首次提供康山变质杂岩的Sm-Nd等时线年龄(1182±50Ma)，否定了康山变质杂岩是太华群的传统认识，并提出康山变质杂岩内斜长角闪岩原岩主要来源于大陆岩石圈地幔，同化混染了少量壳内物质。

An ophiolitic melange belt is discontinuously exposed in Harihada- Chegendalai area to the south of Tuilamamiao in NE of Damaoqi. The ophiolitic mélange in the belt are mainly composed of metamorphic peridotites, metamorphic gabbros, metamorphic basic lavas and high-Mg diorites.

在达茂旗东北推喇嘛庙南15km的哈日哈达-车根达来地区，断续出露一套由变质橄榄岩、变质辉长岩、变质基性熔岩以及高镁闪长岩组成的蛇绿混杂岩。

Esistence of periclasite and wollastonite and the feature of the texture and structure of ores indicate existence of contact metamorphism in formation of the deposit.

但方镁石、硅灰石等矿物的存在和矿石结构构造的特点，表明矿床的形成还存在接触变质作用，矿床成因应属于区域变质－接触变质复合类型。

The zircon mineralogy and chronology of the eclogite show that a lot of primary inclusions of omphacite,phengite,garnet,bariosite etc.occur in the zircons,so the zircon should be formed during eclogite facies metamorphism.SHRIMP dating for zircons suggests the age of eclogite facies metamorphism range from 230 to 243Ma.

锆石矿物学和SHRIMP年代学研究表明，榴辉岩锆石中含有大量的绿辉石、多硅白云母、石榴子石、冻蓝闪石等矿物原生包裹体，锆石为榴辉岩相变质作用过程中从形成的变质锆石，锆石SHRIMP U—Pb年龄在230～243Ma之间，代表榴辉岩相变质作用的时代。

Iodine levels increase from lignite through subbituminous coal and bituminous coal to anthracite,it indicates that coal adsorbed excess iodine from the hydrothermal fluids during the process of metamorphism,including geothermal metamorphism and telemagmatic metamorphism.

从褐煤、亚烟煤、烟煤到无烟煤，碘的含量越来越高，表明在变质作用(含深成变质作用和区域岩浆热变质作用)过程中煤吸收了热液流体中的碘。

Have produced the natural radioactive level of the colliery of Yunnan through the investigation: Mainly it is brown coal , it is low bituminous coals rotten, in bituminous coal and levels radioactives natural of bituminous coals rottens highs rotten.

通过调查得出了云南煤矿的天然放射性水平：主要是褐煤、低变质烟煤、中变质烟煤和高变质烟煤的天然放射性水平。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
