格陵兰岛伊犁马萨克碱性杂岩原生矿石矿物研究进展

Advances in Research on Primary Ore Minerals in the Ilimaussaq Alkaline Complex,Greenland

格陵兰伊犁马萨克杂岩是世界最大的碱性杂岩之一,以盛产稀有矿物而闻名,已发现的矿物超过230种。斯坦硅石和异性石由于富含稀土、铀,是杂岩体中重要的矿石矿物。斯坦硅石主要分布于杂岩体钠铁闪石异霞正长岩内,异性石主要分布于条纹霞石正长岩中。文章基于前人研究,从岩体产出环境、岩石组成、勘探历史、矿石矿物类型及蚀变特征等方面进行了系统总结。

The Ilimaussaq complex in Greenland is one of the greatest alkaline complexes in the world.It is famous for its abundant rare minerals with more than 230 rare minerals.Steenstrupine and eudialyte rich in REE and uranium are 2 important minerals in the complex.Steenstrupine occurs in arfvedsonite lujavrite of the complex and eudialyte occurs in ribbon nepheline syenite.This paper systematically summarizes occurrence,rock association,mineral species,wallrock alteration characteristics and exploration history according to the previous data.
