多硅白云母

The correlation analysis demonstrates that the hydroxyl content of omphacite is correlated positively with the MgO, TFeO and Al2O3 contents, and negatively with the Na2O content of the whole rock and the Na2O and TFeO contents of omphacite, but is not related with the peak metamorphic conditions.

相关性分析显示，绿辉石的结构水含量与全岩的Mgo、TFeO、Al2O3，含量成正相关，与NaO成反相关，与绿辉石的NaO、TFeO含量成负相关，与榴辉岩的峰期变质条件无关；与其它类型榴辉岩相比，多硅白云母榴辉岩中绿辉石的结构水含量较高，平均为339ppm。

Within the diamond anvil cell, the Raman spectroscopic study of phengite was developed at room temperature and under various pressures from 1 atmp to 20 GPa.

在金刚石压腔中，通过原位拉曼光谱研究了多硅白云母在常温高压下的稳定性。

Thise granitic gneisses also lack those typical texture that can reflect had undergone UHP metamorphism which are common in paragneisses ,such as biotite reaction rim of phengite.

同时花岗片麻岩中缺少副片麻岩中常见的一些能反映经历过超高压变质作用的特征性结构，如多硅白云母周围的黑云母反应边结构。

The mode of OH- band and the intensity decrease linearly with the increase of pressure, i.e., y=-0.3402 x+3617.8 and R2=0.9662, and the mode disappears at 18 GPa, which is assumed to be the maximum pressure for the dehydration of phengite at room temperature.

羟基3618cm^-1谱峰则随压力增加向低频方向移动，谱峰的降低与压力的增加呈明显的线性关系变化（y=-0.3402X＋3617.8，R^2=0.9662），并且强度随着压力的增加也在逐渐减弱，在压力达18GPa时开始消失，推测该压力可能为多硅白云母在常温下脱羟基的极限压力。

The Ar - Ar ages of 214～219Ma and 217～223Ma for phengite from the eclogite and its country rock, respectively,record the final exhumation stage of the eclogite.

榴辉岩及其同岩中多硅白云母Ar—Ar年龄分别为214～219Ma和217～223Ma，代表其折返到地表的时代。

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 ultra-high pressure metamorphic rocks distributed in the southern Dabie Shan have different rocks types including eclogites, garnet pyroxenite and garnet peridotite, quartz jadeitite, acid gneiss, phengite- quartz schist and marble.

分布于大别山南部的超高压变质岩具有丰富的岩石组合，主要岩石类型有榴辉岩、石榴辉石岩和石榴橄榄岩、石英硬玉岩、酸性片麻岩、多硅白云母石英片岩及大理岩等。

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。

Coesite + garnet + omphacite + rutile and coesite + phengite + apatite in zircons from phengite-bearing rutile quartz eclogite.

金红石石英榴辉岩锆石中保存的典型超高压包体矿物组合为柯石英+石榴石、柯石英+石榴石+绿辉石+金红石和柯石英+多硅白云母+磷灰石。

The coesite-diamond-bearing eclogite distributed in the northern part of the UHPM belt suffered three stages of metamorphism. The first stage is the Ep amphibolite facies metamorphism, which is represented by the paragenesis of phe+Qtz+Cro/Bar Bar+Ep+Ab occurred as inclusions in Grt and Omp; The second stage is the peak metamorphism of eclogite facies with mineral assembledge of Grt+Omp+Coe±Dia±Ky±Zo±Phe+Rt. The P -T condition is 800±50℃,≥28Kb; The third stage is the amphibolite facies retrograded metamorphism from the peak one, which can be divided intothe early amphibolite facies stage with the mineral assembledge of Amp+ Pl+Di+Qtz±Ep+Ilm/Ttn and the late greenschist facies one with the mineral assembledge of Ep+Chl+Bi+Tr+Ab.

分布于超高压变质带北侧的柯石英榴辉岩经历了3个阶段的变质作用：(1)早期绿帘—角闪岩相阶段，以出现在石榴石和绿辉石中的包体矿物多硅白云母、石英、冰蓝闪石或青铝闪石、钠长石等为代表；(2)峰期柯石英榴辉岩相阶段，其矿物组合为Grt+Omp+Ky+Phe±Zo+Coe±Dia+Rt，其变质温度压力为800±50℃，≥28Kb；(3)退化变质作用阶段，早期为角闪岩相，以Amp+Pl+Di±Ep+Qtz+Tit等退变矿物组合为代表；晚期为绿片岩相，以绿帘石、绿泥石、黑云母、透闪石及钠长石等矿物为代表。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
