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。
2.
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。

补充资料：硬玉
分子式：NaAl[Si2O6]
CAS号：
性质：单斜晶质系。晶体极少见到，通常成隐晶质致密块体。莫氏硬度6.5～7。相对密度3.3～3.4。玻璃光泽。以苹果绿色最常见，也有呈浅绿色或白色。质地坚韧。刺状断口。产于碱性变质岩中。硬玉又名翡翠，是一种名贵的玉石，可供雕琢高级工艺美术品。但一般将坚硬隐晶质的其他绿色矿物如绿石髓、软玉(角闪石的一种)等均称翡翠。
