粤西广宁岩体离子吸附型稀土矿稀土元素特征分析

Analysis of rare earth element characteristics of ion⁃adsorbed rare earth ore from Guangning rock mass in Western Guangdong

粤西是广东省稀土资源重要成矿潜力地区之一,其中广宁地区稀土矿为风化壳离子吸附型稀土矿,含矿原岩广宁岩体分布范围广,成矿背景良好。本文基于现有人力冲击取样钻中全风化层稀土元素含量测试,从成矿控制条件、分布富集规律等方面对广宁岩体的离子吸附型稀土矿成矿规律进行了分析,并圈定了若干个远景区。

Western Guangdong is one of the important metallogenic potential areas of rare earth resources,among which the rare earth ores in Guangning area are classified as weathering crust ion⁃adsorbed type rare earth ores.The ore⁃bearing protolith,Guangning rock mass,are widely distributed and have favorable metallogenic background.In this paper,based on the measurement of REE content obtained from comprehensive sampling of the entire weathered layer using manual impact sampling drill,the metallogenic regularity of ion⁃adsorbed REE ore in Guangning rock mass has been analyzed from the aspects of ore⁃forming control conditions,distribution and enrichment patterns.Futhermore,several prospective areas have been delineated.
