| 摘 要： | 梅山铁矿在矿床地质特征、成矿流体来源、氧同位素的组成、实验岩石学资料以及稀土元素分布特征等方面，都充分体现了矿浆成因观点的正确性。特别是磁铁矿及其围岩中稀土元素的系统研究，为进一步探讨矿浆成因铁矿提供了新途径

| Abstract: | The reliability of the viewpoint of ore magma genesis for Meishan iron ore deposits is interpreted on the basis of six respects: the geological characteristics of the iron deposits, the field observation with the genesis, the mass source of the ore forming fluid, the composition of O isotope, the materials of experimental petrology and the distribution of rare earth elements (REE) relating to Meishan iron ore deposits. Especially the systematical studies of REE patterns in magnetites and REE partition coefficients between magnetites and silicate rocks give a new way for further approach of iron ore deposits from ore magma. |
