A Special Rare-earth Mineral —Eudialyte

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.
