绿辉石

Through electron probe\'s analysis to the albite jade, union grinding sample thin slice under polarizing microscope observation as well as X powder crystal diffraction data analysis. Discovery like Chen zhenqiang and "System Gemology" said that secondary mineral for actinolite, green mudstone, epidote and quart.

通过对钠长石玉进行电子探针的分析，结合磨制的样品薄片在偏光显微镜下的观察以及X粉晶衍射数据分析，可知钠长石玉中的主要成分为钠长石，次要矿物为硬玉、角闪石、绿辉石、钠铬辉石；并未发现如陈振强等人以及《系统宝石学》中所说的次要矿物为阳起石、绿泥石、绿帘石、石英。

Comparing with the omphacite fabric plots shows that the [001] preferred orientation is parallel to stretching lineation, meaning that the omphacite LPO is the main cause of seismic wave anisotropy.

实测波速的最大和最小值分别为平行线理和垂直面理方向，对比绿辉石的组构图就会发现，[001]极密方向即为线理方向，这说明绿辉石LPO是形成超高压榴辉岩波速各向异性的主要因素。

Omphacite jade or omphacitic jadeite jade, commercially named Inky Black Jade, is a virtually monomineralic rock composed of more than 90% omphacite .

绿辉石玉或绿辉石质翡翠是由 90 %以上的绿辉石组成的基本上为一种单一矿物的玉石，其颜色为墨绿色，透明度高，商业上俗称墨翠。

Classify omphacite, kosmochlor and Jadeite Jade by means of analysing and calculating the chemical

其化学成份含量的分析和计算，对绿辉石、钠铬辉石及硬玉的种类准确分类有良好的表现。

The influence of Fe(superscript 2+) adjustment in omphacite on the p-t conditions has been discussed by comparison, and the charge balance method has been recommended as the ideal one for Fe(superscript 2+) adjustment in omphacite.

本文通过对南大别太湖地区和桐城地区榴辉岩中绿辉石的四种Fe(上标 2+)的校正比较，依据计算的峰期变质p-t条件和岩相学研究的限定，探讨了绿辉石Fe(上标 2+)的校正对温度压力计算的影响，认为电价平衡是目前较为理想的校正绿辉石Fe(上标 2+)的方法，并建议为保证分析的准确性和全面性，配合使用端元组分调Fe(上标 2+)法和Fe(上标 2+)/Fe(上标 3+)=1：1方法。

Flinn plots show that, both garnet and omphacite are belong to constriction ellipsoid, which is stretching strain, being similar with the result of omphacite fabric.

6付林图解表明，绿辉石和石榴子石均属于收缩型椭球，拉伸型应变，这与绿辉石组构测定结果一致。

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。

The article has researched occupation of ions in jadeite, diopside and omphacite in jadeite jade on the base of 222 components data. The author has calculated all theie formula and testified that ∑ and ∑ should be positive correlation.

以222点电子探针的化学成分为依据，研究了翡翠中重要组分矿物硬玉、绿辉石和钠铬辉石的离子占位，离子间交换规律等，着重讨论了透辉石—绿辉石—硬玉固溶体系列的类质同象替换，并通过对所有成分点的晶体化学式的计算，验证了∑与∑呈正相关等理论。

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。
