在混合岩化后期,某些稀有和放射性元素可以活化、迁移和富集,在国内外文献中已有较多阐述。本文报导一个硼铁矿床中含稀土矿化的电气石、透辉石交代岩,是混合岩化成矿的稀土矿床新类型。 在凤城硼镁铁矿—磁铁矿矿床中,含稀土矿化首先由长春地质学院硼矿科研组发现。作者在对矿化分布规律及岩石矿物学特征研究基础上确定它是一个独特的稀

In the late stage of mixed rockification, some rare and radioactive elements can be activated, migrated and enriched, which have been elaborated in domestic and foreign literatures. This paper reports that a rare-earth mineralized tourmaline and diopside replacement rock in a boron-iron ore bed is a new type of rare-earth mineralization mixed mineralization. In Fengcheng bauxite - magnetite deposit, with rare earth mineralization first discovered by the Changchun Institute of geology boron research group. Based on the study of mineralization distribution and rock mineralogy, the author determined that it is a unique and dilute
