河北省隆化县瓦房重稀土矿地质特征初探

Preliminary Study on the Geological Characteristics of Wafang Heavy Rare Earth Deposit in Longhua County,Hebei Province

《全国矿产资源规划(2016-2020年)》将稀土矿产列为战略性矿产目录,伟晶岩型稀土矿为稀土矿重要组成部分。以河北省瓦房伟晶岩型重稀土矿化体为研究对象,采用野外地质调查、采样分析、归纳总结等的研究方法,初步研究了矿区地质、矿床地质等特征。研究结果表明:该矿区重稀土矿成因类型为伟晶岩型重稀土矿床,矿化体呈脉状近东西向平行排列,赋矿矿物褐钇铌矿产于正长花岗伟晶岩中。矿区附近成矿地质条件良好,寻找伟晶岩型重稀土矿的潜力巨大。

Rare earth minerals were listed as strategic minerals in《National Mineral Resources Planning》.And the pegmatite type is an important part of the rare ree minerals.Taking the Wafang pegmatite-type heavy rare earth mineralization in Hebei Province as the research object,we study the character of mineral deposit by field geological investigation,sample analysis,induction and summary.The results show that the origin type of heavy rare earth ore in this mining area is pegmatite type heavy rare earth deposit,the mineralization is vein-like and arranged in the near east-west direction,and the mineral brown yttrium niobium ore is in the orthogranite pegmatite.The mineralization geology near the mining area is good,and the potential for finding pegmatite-type heavy rare earth ores is huge.
