摘　　要：对产于青海锡铁山铅锌矿氧化带中的锡铁山石进行了５７Ｆｅ穆斯堡尔谱的研究，在晶体结构分析的基础上进行了谱峰的重新解释，发现由于配位Ｃｌ－离子无序占位引起Ｆｅ３＋离子所占配位八面体的畸变，形成了Ｆｅ３＋的两种亚晶位，并根据结构数据指定了这两种亚晶位各自形成的四极双峰。Xitieshanite occurres in the oxided zone of Xitieshan Lead_zinc Deposit in Qinghai Province,its Mossbauer spectrum has been measured at room temperature.Based on the crystal structural analysis,we gave a new interpretation of its spectrum,ascertained 2 sub sites of Fe 3+ cation in the crystal structure of Xitieshanite, which caused by the disorder occupation of coordination Cl - in the coordination octahedron of Fe 3+ cation,and assigned the quadrupole splittings formed by the Fe 3+ cation in 2 sub-sites respectively.
