Based on the investigation, inclusions in jadeite from Burma are divided into four types.
显微分析表明,缅甸硬玉中的包裹体分为4种类型:固体包裹体、流体包裹体、流体-熔融包裹体和熔融包裹体。
in jadeites from Burma were analyzed by micro-FTIR spectrometry.
缅甸硬玉的微区显微红外光谱中出现的OH、C—H、C O基团的定量比较分析表明,在不同颜色硬玉中其浓度差异明显;说明硬玉的颜色与物化环境的局部变异密切相关,是在一个复杂的有机与无机的天然环境中形成;在合成不同颜色硬玉时,需与适当的物化环境相匹配,尤其是绿色硬玉,才有利于硬玉的生长。
This paper presents a new viewpoint that there exists the desalinization of chromium within the Myanmar jadeite jade,which plays an important role in genesis and evolution of green colour of the jadeite jade.
缅甸翡翠中“Cr的淡化”可划分为4个阶段:(1)铬铁矿→钠铬辉石,该阶段是交代反应,形成冠状和柱粒状结构;(2)钠铬辉石→铬硬玉,该阶段是交代—置换反应;(3)铬硬玉→含Cr低的硬玉[w(Cr2O3)约为0。
Jadeitite is a kind of jadeite aggregates.
翡翠是以硬玉为主的集合体,翡翠原生矿床是伴随着印度板块与欧亚板块碰撞过程中形成的。
The quality of jadeite is decided by its color and texture.
其中辉石族的矿物如硬玉、霓石、钠铬辉石、钙铁辉石,它们的存在和数量的多少及化学成分的变化对翡翠的质量影响很大。
A few pieces of green synthetic jadeite jade stone are studied by using X-ray powder diffraction, polarizing microscope, EPMA, infared reflectance spectrum and laser Raman spectrum.
通过X射线粉末衍射、偏光显微镜、电子探针、红外显微镜微区反射光谱、激光拉曼光谱等测试手段对几件绿色合成硬玉玉石样品进行仔细研究后发现,它是由结晶质和玻璃质物质组成,结晶质部分很少,结晶矿物为自形的长柱状硬玉,玻璃质物质的成分与硬玉的化学成分基本接近,但其w(SiO2)和w(Al2O3)明显偏高,而w(Na2O)明显偏低。

The textures of Myanmar jadeitites are classified into three major types according to the forming stages and the petrographic features: primary texture, deformed-metamorphosed texture and post-filled texture, and their gemmological implications are discussed.
依据其形成阶段及岩相学特征将缅甸硬玉岩的结构首次分为三大类:原生结构、变形变质结构及后生充填结构。
Jadeitite is a well known but rare rock type that is found only in a few places in the world.
硬玉岩是一种稀少的岩类,常以构造岩包体和脉体的型式产出在蛇纹岩中。
The research indicates that Hte Long Sein Jade mainly consistsof chromium-rich jadeite, which occurs as mineral aggregate (>75% ), The crystal chemical formula ofchromium-rich jadeite shows as (Na0.
结果表明,优质铁龙生玉主要由富铬硬玉矿物集合作组成(>75%),晶体化学式为:(Na0。
