摘　　要：本文介绍了雅满苏铁矿区玄武岩、矽卡岩和铁矿石的稀土元素地球化学特征，并就其相似性和变异特征，探讨了成岩成矿物质来源和成矿作用过程，结合Ｓｒ、Ｓ、Ｃ等同位素资料，提出了成岩成矿物质来自下地壳或上地幔．成矿作用过程中，火山气液交代充填－矿浆贯入占重要地位．The rare earth elements distribution patterns and geochemical characteristics of the basalts, shams, and iron ores in the Yamansu iron deposit are introduced in this paper. The origin of the diagenetic and mettallogentic materials and the mettallogenic process are discussed according to the similarity as well as variability of the patterns, it is proposed that the materials come from the lower crust or upper mantle by studying the Sr,S, and C isotope data. The gas-liquid replacement plays an important role in forming the deposit.
