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。

The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.
研究发现我国白云母主要产地的大片白云母均为普通白云母,变质岩地区的碎白云母以多硅白云母为主;本文研究的印度的大片白云母、碎白云母均为普通白云母;印度白云母基片的表面活性高于我国白云母;酸处理容易沿平行于白云母基面的方向侵蚀,虽未使白云母晶体结构产生破坏,但造成了白云母热稳定性降低。

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.

In the detrital zircon sample FH4, which was collected from lower sandstones of the Fanghushan Formation, the oldest sedimentary strata of the Hefei Basin. HP-UHP mineral inclusions such as coesite, omphacite, phengite and melt inclusions, and other minerals like apatite, quartz, feldspar, white micas were identified by means of micro-laser Raman spectrometer and electron probe.
防虎山组的下部砂岩地层是合肥盆地最古老的中生代沉积地层,在样品FH4中选出了碎屑锆石,通过显微激光拉曼光谱、电子探针的研究发现,锆石中含有柯石英、绿辉石、多硅白云母等典型的高压-超高压矿物包裹体、熔体玻璃包裹体以及磷灰石、石英、斜长石、白云母等矿物包裹体。

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 peak metamorphic minerals are garnet, omphacite,phengite and rutile with temperature of~500℃,pressure of~2.3Gpa.On the basis of geochemical analysis,the content of SiO2 in the eclogite ranges from 46.68%to 50.24%,Na2O+K2O 3.10~4.21%,and high REE with enriched LREE, LREE/HREE of 2.83~6.06.The REE pattern and trace element spidergram are similar with those of ocean island basalt,according with the blueschist from Longmucuo -Shuanghu suture zone.The protolith of the eclogite and blueschist are OIB,and they aremaybe the result of subduction of Permian OIB in central Qiangtang area.
对棉辉岩的地球化学分析显示,榴辉岩SiO_2含量在46.68—50.24%之间,Na_2O+K_2O含量在3.10—4.21%之间,稀土元素总量较高,轻稀土富集,重稀土相对亏损,LREE/HREE比值在2.83—6.06之间,稀土元素球粒陨石标准化曲线呈向右倾斜的样式,微量元素原始地幔标准化蛛网图OIB类似,这些特征和龙木错—双湖高压变质带的蓝片岩类似,它们的原岩为均为洋岛型玄武岩,形成环境类似于现在太平洋中的夏威夷,榴辉岩、蓝片岩很可能是羌塘中部地区出露的二叠纪洋岛型岩石俯冲消减的产物。
