| 摘 要： | 随着贵州西部地区毕节、威宁、赫章等地玄武岩风化壳中离子吸附型稀土矿点的发现，广泛分布于川滇黔三省的峨眉山玄武岩成为一个新的离子吸附型稀土矿重点找矿远景区。本文初步探析了云南宣威地区离子吸附型稀土矿成矿条件，结合赣南地区离子吸附型稀土矿找矿经验，提出了云南宣威地区快速圈定稀土矿找矿靶区的思路。通过云南宣威地区某项目找矿实践，在区内共圈定4个离子吸附型稀土矿找矿靶区，取得了较好的找矿效果。

| Abstract: | With the discovery of ion-adsorption rare earth ore points in weathering crust of basalt in Bijie, Weining and Hezhang in western Guizhou, the Emeishan basalt widely distributed in Sichuan, Yunnan and Guizhou Provinces has become a new and focused potential area of search for ion-adsorption REE ore. This paper analyses the ore-forming conditions of ion-adsorbed REE in the Xuanwei area of Yunnan Province. Combined with the experience of prospecting for this ore in southern Jiangxi Province, an idea of quickly locating the target area in the Xuanwei area of Yunnan is put forward. Through mining practice of a project in the Xuanwrei area of Yunnan, four target areas of ion-adsorption REE ore have been determined showing a good effect of this endeavor. |
