通过穆斯堡尔谱，研究了江苏盱眙龙王山收集的富铁坡缕石的热分解过程与Fe原子占位，分析结果表明，在样品中Fe呈三价，占据层链中的M1位和M2位八面体，比例为3：1。

英文摘要：

In this paper, Mossbauer spectra were used to research thermal decomposing process and the occupation of Fe ions in iron rich palygorskite, which is collected from Longwangshan, Xuyi, Jiangsu Province. It is indicated that Fe ions are in ferric and occupy both M1 and M2 of octahedral ribbon with a ratio close to 3：1.
