摘　　要：这是一篇地球科学领域的论文,主要阐述了碱性岩中的一种含稀土矿物-异性石的基本特征。异性石是一种常见的岩浆岩副矿物和热液矿物,易受风化和氧化等表生作用影响,能较好记录和保存岩浆和热液活动的原始信息,因而是研究岩浆和/或热液过程的一种常见示踪矿物。通过文章的综述,希望能够为深化异性石矿物学和地球化学研究、加强异性石型稀土矿方面的找矿工作、广泛开展与异性石有关的地质问题探讨等提供较全面的基础性认识。This is an essay in the field of earth science,which mainly reviews the basic characteristics of eudialyte,a rare earth-containing mineral in alkaline rocks.Eudialyte is a common accessory mineral and hydrothermal mineral of magmatic rock,which is vulnerable to weathering and oxidation and other epigenetic effects.It can better record and preserve the original information of magma and hydrothermal activities,so it is a common tracer mineral for studying magma and/or hydrothermal processes.Through the review of the article,we hope to provide a more comprehensive basic understanding for deepening the Mineralogy and geochemical research of Eudialyte,strengthening the prospecting work of Eudialyte REE deposit,and widely carrying out the discussion of geological problems related to Eudialyte.
