云母岩

The conventional 40Ar/39Ar age of muscovite in high-pressure metamorphic orthogneiss, surrounding rocks of the Qinglongshan eclogite, is identical with its Rb-Sr and Sm-Nd ages.

作为东海青龙山榴辉岩围岩的高压变质的正片麻岩，其白云母的常规~(40)Ar/~(39)Ar年龄和Rb-Sr、Sm-Nd年龄一致，激光微区Ar同位素分析表明，白云母的Ar同位素分布也是均匀的。

The lower lithospheric mantle in western Shandong could be composed of Group Ⅰ inclusions which were subjected to orthopyroxene vein or orthopyroxene+ phlogopite vein and disseminated phlogopite metasomatism.

鲁西区软流圈的顶部，即岩石圈地幔的底部应为一套组Ⅰ型包体，它们存在斜方辉石交代脉体和斜方辉石+金云母的交代脉体以及弥漫型金云母；向上(约43～57km±)为一套堆积岩。

These two ores have contrasting mineral associations: anthothyllite + plagioclase + rutile + magnesiohornblende + alkline fledspar for red ore and anthothyllite + phlogopite + epsode + Rutile for black ore.

根据岩相学观察，认为红色金红石矿中存在如下方向的反应：镁角闪石+碱性长石→直闪石+／-斜长石+／-金云母，斜长石很可能只是过渡相，反应最终将形成直闪石+金云母。

The quartz in this region shows a array of deformations from High-temperature -High pressure condition to crust environments: coesite → the high-temperature quartz → sheared quartz vein → feldspathic shear zone (the quartz from two-mica schist)→ the ordinary quartz in eclogites.

7本区石英的变形构成了一个从高温高压到中上地壳的连续变形序列：柯石英→榴辉岩中高温石英→剪切石英脉→长英质剪切带(超高压二云母片岩中石英)→榴辉岩中普通静态重结晶石英。

The muscovite-chlorite geothermometer, muscovite-biotite geothermometer and chlorite compositional geothermometer that are suited to the low-temperature conditions have only been used in the interpretation of regional metamorphism of sedimentary rocks and have never been used for mylonites of ductile shear zones.

适用于低温条件下的白云母-绿泥石地质温度计，白云母-黑云母地质温度计和绿泥石成分温度计仅在区域变质岩中应用过，从未在糜棱岩中使用。

According to cpx-melt equilibrium pressure, the xenoliths types and simulating calculating of host rock REE partition pattern, source of sodic basalts is garnet lherzolite mantle, and the source of potassic basalt is metasomatic fluid altered phlogopite-containing garnet lherzolite mantle. For the alkaline basalts to sub-alkaline basalts, the melting degrees of the source rocks are 4%～15%.

根据单斜辉石—熔体平衡压力计算、所携带的包体类型及玄武岩稀土元素配分曲线的非实比部分熔融定量模拟表明，钠质玄武岩的来源为石榴石二辉橄榄岩源区，五大连池钾质玄武岩的源区是被交代的含金云母石榴石二辉橄榄岩源区，研究区碱性玄武岩到亚碱性玄武岩是石榴石二辉橄榄岩源区经4％～15％部分熔融程度的产物。

Because whole rock samples always contain some retrograde minerals,the tie line of garnet + whole-rock in Sm-Nd isochron diagram or the tie line of phengite + whole- rock in Rb-Sr isochron diagram can give a geologically meaningless age.

由于全岩样品总是含有数量不等的退变质矿物，因此石榴石+全岩 Sm-Nd 法或多硅白云母+全岩 Rh-Sr 法将有可能给出无地质意义的年龄。

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。

The feldspars from the γA1 and γAIIa show many clear metasomatic alteration features; the- refore, the authors genetically consider the albitized protolithionite granite and the albitized zinnwaldite granite to be metasomatic altered granites.

花岗岩中长石具有清楚的交代特征，晚期岩体中的钾长石的An和Ab组份十分低，斜长石中的An和OI组份也很低，说明钠长石化黑鳞云母花岗岩和钠长石化铁锂云母花岗岩为交代蚀变花岗岩。

The rocks of early Proterozoic and Archaean contain the lower potassium feldspar and lead number in potassium feldspar is lower than 10% of lead in the whole rocks.

中文摘要：在中-酸性岩浆岩、碱性岩浆岩、片麻岩及混合岩等岩石类型中，钾长石是含铅最高的造岩矿物，其铅含量是全岩铅含量的2～10倍，云母类矿物铅含量的3～16倍，石英铅含量的6～32倍。

By using competitive adsorption of activated carbom to remove unfavorable influence of carbon in carbonaceous gold concentrate on leaching process, the leaching rate of gold concentrate can be improved to 88% as compared with 10%by direct cyanidation.

本文论述了利用活性炭竞争吸附作用，消除含炭金精矿中炭在浸出过程中的影响，使金精矿的浸出率可由直接氰化的10％提高到88％。
