本文对雪宝顶绿柱石的晶体化学、矿物谱学、热释光和流体包裹体特征等进行了分析讨论。结果表明 ,雪宝顶绿柱石化学成分具有富碱、富水 ,过渡金属离子以Fe3+、Fe2 +为主的特点。碱金属离子、水和Fe2 +存在于绿柱石结构隧道中 ,隧道水分为Ⅰ型和Ⅱ型两类 ,Ⅰ型水可以进一步区分为Ⅰ1和Ⅰ2 两亚类 ,Fe2 +主要与隧道水结合形成水合离子 [Fe2 +(H2 O) ]。Fe3+主要占位于绿柱石AlO6八面体中的Al3+位 ,是导致绿柱石呈浅绿色的主要杂质离子。绿柱石的热释光强度和峰温可作为其标型特征之一。成矿溶液属于气成高温热水溶液 ,且富含大量碳酸或碳酸气。
In this paper, the crystal chemistry, mineralogy, thermoluminescence and fluid inclusion features of Xuebaoding beryl were analyzed and discussed. The results show that the chemical composition of Xuebaoding beryl has the characteristics of rich in alkali, rich in water and transitional metal ions with Fe3 + and Fe2 +. Alkali metal ions, water and Fe2 + are present in the beryl structural tunnel. The tunnel water is classified into type I and type II. Type I water can be further divided into two subtypes I1 and I2. Fe2 + is mainly combined with tunnel water to form hydration Ion [Fe2 + (H2 O)]. Fe3 + mainly accounts for Al3 + in the beryl AlO6 octahedron of beryl, which is the main impurity ion that causes beryl to be light green. Beryl thermoluminescence intensity and peak temperature can be used as one of its standard features. Mineralization solution belongs to the gas into a hot solution of high temperature, and rich in carbonated or carbonated gas.
