钠长石

By synthesizing the influence of the two albite's occurrence towards feicui's structure, transparency, color and many other factors, we can reasonably get the conclusion that the existence of albite will reduce the quality of feicui.

综合两种产状的钠长石对翡翠的结构，透明度，颜色等诸多因素的影响，得出结论，钠长石的存在将会降低翡翠的质量。

The second part for the existence form water in albite jade. Through infrared spectrum analysis to albite jade in whether to contain water as well as the water type.

第二部分为钠长石玉中水的存在形式的研究，通过红外光谱分析对钠长石玉中是否含水以及水的种类进行分析。

In view of these realistic questions, this article conducts system albite jade gemology research and clarifies to the albite jade part dim consciousness, makes some essential supplements to the jewelry jade\'s research.

针对这些现实题目，本文进行系统的钠长石玉宝石学研究，澄清对钠长石玉的部分模糊熟悉，对珠宝玉石的研究做一些必要补充。

They crystallized in veins that are several centimeters in diameter, which were made up mainly of calcite, sodium feldspar albite, and iron sulfite pyrite.

它们体现在那些静脉直径几厘米，其中大部分为方解石，钠长石钠长石，黄铁矿和铁的亚硫酸盐。

Therefore, I on raise the question to Chen Zhenqiang and "System Gemology" about the albite jade chapter, and the opposite amphibole\'s subspecies have carried on the division.

因此，本人对陈振强以及《系统宝石学》上关于钠长石玉章节的钠长石玉的矿物组成以及组成矿物化学成分部分提出质疑，并对角闪石的亚种进行了划分。

Obtains its physical property through the gemology convention test the related parameter, has carried on the division for the first time according to the albite jade\'s physical property reference jadeite\'s classification to the albite jade\'s idioplasm.

通过宝石学常规测试得出其物理性质的相关参数；根据钠长石玉的物理性质参照翡翠的分类首次对钠长石玉的种质进行了划分。

On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.

通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究，可以得出以下结论：(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动，同时高频区(850-1300cm〓)不断变窄且向低频区方向移动，这表明随着压力升高T-O-T键角不断减小，并且分布范围变窄，T-O-T键角这种变化从而可使T-O键的力常数减小，导致键强减弱；另外，580cm〓谱峰强度随着压力升高不断减弱，并在0.8-1.0GPa时最为显著，这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。

In comparison with the petrography and petrochemistry of hydrothermal sedimentary albitite in the Devonian of the Qinling, combined with the fact that its Lower Paleozoic belongs to a passive continental-margin rift environment on the northern margin of the Yangtze plate,the authors think that the Lower Paleozoic albitite in question is probably of hydrothermal sedimentary origin.

通过与秦岭泥盆纪热水沉积钠长石岩的岩相学及岩石化学对比，结合本区下古生界属于扬子北缘被动陆缘裂谷环境，初步认为这里下古生界钠长石岩可能属于热水沉积成因。

Na-rich rocks include albitite ,arfvedsonite-bearing albitite dyke,arfvedsonite dyke,and arfvedsonite-bearing .

富钠岩石包括富钠长石岩、含钠闪石钠长岩脉、钠闪石岩脉及钠闪石碳酸岩脉和钠闪石化蚀变白云岩。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。
