摘　　要：德昌大陆乡稀土矿位于康滇前陆逆冲带北部(攀西裂谷带)和盐源-丽江逆冲带北东部结合部位,介于磨盘山断裂带与金河断裂带之间。本文通过研究区域地质背景及矿区成矿地质环境、矿体特征基础上,对矿床成因进行分析总结,建立成矿模式,认为该矿床成矿模式为深源-浅成-岩浆成矿。Dechang Dalu township rare earth mine is located in the northern part of Kangdian foreland thrust belt(Panxi rift zone)and the north-east part of Yanyuan-Lijiang thrust belt,which is between the Mopanshan fault zone and Jinhe fault zone.Based on the study of regional geological background,metallogenic geological environment and ore body characteristics,this paper analyzes and summarizes the genesis of the deposit,establishes the metallogenic model,and considers that the metallogenic model of the deposit is deep-source-shallow-magmatic metallogenesis.
