| 摘 要： | 含紫硅碱钙石、镁钠钙闪石（钠透闪石－石棉）及蓝色软透闪石的碱性交代岩的形成首先是由硅酸和碱（Ｎａ２Ｏ和Ｋ２Ｏ的不同作用）的隋性及ＦｅＯ，ＭｇＯ，ＣａＯ和Ａｌ２Ｏ３的强烈活性决定的。含蓝色软透闪石和镁钠钙闪石（钠透闪石－石棉）的交代岩是岩浆期后溶解演化的中期产物，而含紫硅碱钙石的交代岩却是其晚期的产物。

| Abstract: | The formation of alkaline metasomatites with charoite, potash richterite (richterite asbestos) and blue nephrite is conditioned by inert behaviour, first of all, of silicic acid and alkalis (with a varying role of Na 2O and K 2O) and by quite mobile FeO, MgO, CaO, and Al 2O 3. Metasomatites with blue nephrite and potash richterite (richterite asbestos) appear at the intermediate, and those with charoite at the final stages of evolution of postmagmatic solutions. |
