角闪石

The other jade mineral is nephrite, which is a variety of actinolite.

另一种玉石矿物称为软玉，是角闪石类矿物的变异体。

Nephrite is used to be considered as aphanitic mineral aggregate which belongs to Fe\|poor and Mg\|rich member of actinolite\|tremolite series.

软玉是含水的钙镁硅酸盐矿物集合体，属于角闪石族钙质闪石亚族中的透闪石阳起石铁阳起石系列的矿物。

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。

The Dashankeng gneiss located in the northeastern Dabie mountains is composed mainly of potassium feldspar, plagioclase and quartz with minor hornblende, biotite and allanite, belonging to monzonitic granitic in composition.

北大别东部大山坑片麻岩主要由钾长石、料长石和石英组成，少量角闪石、黑云母和褐帘石，成分为二长花岗质。

Therefore, China ancient times the jade carving major part was the amphibole product.

因此，中国古代玉器绝大部分为角闪石制品。

As one of major mineral phases in the intermediate-mafic intrusions in Southern Taihang Mountains , amphibole can be used to constrain its petrogenesis.

角闪石作为南太行山地区中基性侵入岩中主要组成矿物，其详细的成因矿物学研究对了解该套岩石的形成机理具有重要意义。

The mineral assemblage of mafic-intermediate lavas mainly contains pyroxene and plagioclase, and rarely with amphibole and bitotite.

中基性熔岩的主要造岩矿物是斜长石和辉石，几乎没有角闪石和黑云母。

This paper deals emphatically with the genetic mineralogical characteristics of amphibole, an important rock-forming mineral extensively-distributed in ophiolites of Shangnan-Danfeng are...

本文着重论述了商丹地区蛇绿岩中广泛分布的主要造岩矿物之一，角闪石的主要特征组份、微量元素、晶胞参数、阳离子占位度等成因矿物学特点。

Furthermore,~(40)Ar/~(39)Ar and K-Ar ages of individual mineral indicate that for isotopic age measurement hornblende and biotite are analogously the ideal minerals, while for K-Ar technique hornblend is the best followeed by the biotite, and the feldspar age has to be used with great care.

40Ar/~(39)At和K-Ar年龄结果还表明：角闪石和黑云母均是~(40)Ar/~(39)Ar理想定年矿物，对K-Ar法而言，角闪石最理想，黑云母次之，长石年龄使用要慎重。

We suggest that the CPO of amphibole in retrograded eclogites is probably formed by rigid body rotation and dissolution-precipitation creep of elongate amphibole grains in a less viscous matrix of symplectite.

结合光学显微特征观察，本文认为退变质榴辉岩中的角闪石 CPO 主要受其显著的长柱状和针状结晶习性控制，其形成机制为差异应力条件下的溶解－沉淀定向生长，可能伴随有早期的角闪石微晶的刚性旋转变形。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
