摘要
根据缅甸翡翠矿石颗粒特征及成矿作用 ,将矿石结构分为三种类型。根据翡翠矿床地质特征、矿石化学成分、矿石结构、成矿物理化学条件、成矿物质来源及大地构造环境 ,认为缅甸翡翠矿石是在板块持续碰撞的过程中 ,在岩浆作用、热液交代作用基础上 ,发生变质作用的产物。成矿温度 2 0 0～ 35 0°C,压力 5 0 0～ 80 0 MPa,与蓝闪石片岩密切相关。
Based on the characters of jadeite particle and its mineralization, the textures of jadeite ore from Burma are classified into three types. According to the geological characters of the deposit, chemical composition and texyures of ore, phisical chemical conditions of forming ore, substance source of forming ore and geotectonic environment, jadeite ore is thought to be the result of magmatism, hydrothermal metasomatism and metamorphism in the collision of the plates. The metamorphic temperature was 200~350℃ and the pressure 500~800 MPa. Jadeite ore is closely related to glaucophane schist.
