中文摘要：

利用穆斯堡尔谱，对比研究了广西、河北、内蒙、新疆等地电气石晶体中Fe离子的微观结构特征。首次尝试利用聚类分析的方法来揭示电气石晶体中Fe离子的价态和占位特征。研究结果表明，不同电气石的分类特征明显：河北、广西、内蒙电气石的穆斯堡尔谱特征类似，Fe离子具两种价态，分别占据Fe^2＋（Y）、Fe^2＋（Z）、Fe^3＋（Y）位；新疆电气石中Fe离子呈二价，主要占据Y位及在Y—Z位出现次近邻效应。

英文摘要：

Mossbauer spectra analysis was used to examine microscopic structures of Fe ions in different tourmaline crystals from Guangxi,Hebei, Neimeng and Xingjiang. The valance states and occupation types of Fe ions were revealed by the multi-statistic method of cluster analysis. The results show that the tourmaline crystals from Guangxi, Hebei and Neimeng are characterized by similar Mossbauer spectra, with two kind of valances of Fe ions occupying Fe^2＋ （Y）, Fe^2＋ （Z）and Fe^3＋ （Y）sites respectively. In comparison, bivalence of Fe ions characterizes the Xinjiang tourmaline, which occupy Fe^2＋ （Y） and have a neighborhood effect in the Y-Z site.
