翡翠的矿物组成

翡翠的矿物组成差异是造成翡翠千差万别的重要原因之一。按照矿物的成因，将翡翠的组成矿物分为变质(变晶)矿物、原生矿物和次生矿物三大类。利用偏光显微镜和电子显微镜等方法系统地研究了各类主要矿物的矿物学特征和显微组构特征，对翡翠质量评价以及翡翠的成西机理研究提供了科学依据。

MINERAL COMPONENT OF JADEITE JADE

Mineral component of jade is among the most important causes resulting in various varieties of jadeite jade. According to the origin of minerals formed, the minerals consisting of jadeite jade can be classified as three categories: metamorphic crrstalloblastic minerals, primary minerals and secondary minerals. Mineralogical characteristics and microfabric of the essenttal minerals were studied symatically by using polar microscope and electron microscope. All of these provide scientthe information for quality evaluation and Senesis of jadeite jade.
