【摘要】 翡翠的矿物组成是影响翡翠质量及其物理性质的最根本原因,同时玉石质量也受其结构、构造的影响。辉石类矿物是组成翡翠的主要矿物,次要矿物包括有长石族矿物和闪石族矿物,常见的副矿物有铬铁矿、绿泥石、褐铁矿等。矿物组成的复杂性直接导致了翡翠种类、颜色的多样性变化,同时也对透明度、光泽度、比重、硬度及工艺性能等产生影响。所以,翡翠的矿物组成是质量分级评价最根本的依据,具有很重要的宝石学意义。更多还原

【Abstract】 Mineral component of jadeite is the most basic cause which affecting and physical properties and quality of Jadeite. The jadeite is also influenced by its structure and texture. The pyroxene group minerals is the essential minerals in jadeite. The next important minerals include feldspar, amphibole group minerals. And the accessory minerals in jadeite usually include chromite, chlorite and limonite etc. Complexity of mineral component directly results in the variety of the jadeite category and the change of color, transparence, luster, specific gravity, hardness and processing property etc. So, the mineral component of jadeite is the most basic basis in evaluation of jade quality, and is of very important gemological significance.更多还原
