自20世纪60年代以来，火成岩中的稀土元素矿床在满足对这些元素日益增长的工业需求方面发挥了重要作用。在许多不同的火成岩含有可观的浓度的稀土元素，碳酸盐岩和过碱性硅酸盐岩是这些元素的最重要的来源，无论是历史上和满足预期的增长稀土需求。碳酸岩、过碱性花岗岩类和过碱性花岗岩类稀土成矿的地球化学和矿物学特征的差异反映了其母岩浆来源和演化途径的不同，以及岩浆后热液对原生稀土矿物的改造程度的差异。
Deposits of rare earth elements (REEs) in igneous rocks have played an instrumental role in meeting the growing industrial demand for these elements since the 1960s. Among the many different igneous rocks containing appreciable concentrations of REEs, carbonatites and peralkaline silicate rocks are the most important sources of these elements, both historically and for meeting the anticipated growth in REE demand. The contrasting geochemical and mineralogical characteristics of REE mineralization in carbonatites, peralkaline feldspathoid rocks, and peralkaline granites reflect different sources and evolutionary pathways of their parental magmas, as well as differences in the extent of postmagmatic reworking of primary REE minerals by hydrothermal fluids.
