摘要
翡翠的种质变化多端是由于翡翠的结构多种多样造成的。翡翠的结构是影响翡翠工艺价值的极其重要的因素。翡翠的透光性（水头）、抛光性能等直接取决于翡翠颗粒的粗细及颗粒之间的结合方式。翡翠的结构按成因类型可划分为变晶结构、交代结构、碎裂结构，反映了变质作用的多阶段性。但从翡翠的重叠、交代结构的普遍存在等，可以反映出翡翠的形成经过了多期的和复杂的地质作用。
This paper discusses the definition and the texture types of jadeite jade. The texture is an important element of jadeite jade, which affects not only the varieties of jadeite jade, but also the beauty, transparency and the finishing product of jadeite jade. The texture types of jadeite jade can be classified by the characteristic of the surface(gemmology feature), for example, grain size, grain shape and the relationship of inter-grain, etc. The texture of jadeite jade can be classified into three types according to their geological origin: (1) crystalloblastic texture; (2) replacement texture; (3) cataclastic texture. The three types reflect the three stages of metamorphism.
