福建省万安矿区离子吸附型稀土矿成矿规律研究

Study on metallogenic regularity of ion-adsorbed rare earth ore in Wan'an Mining area,Fujian Province

福建省万安矿区离子吸附型稀土矿区成矿条件优越,找矿前景巨大,是由福建省第八地质大队历时两年多野外地质工作发现的一处大型离子吸附型稀土矿床,矿区花岗岩风化壳较发育,具有有利的成矿母岩与有利的自然环境条件,母岩矿物中的稀土元素大量转变为风化壳中的呈吸附状态的稀土离子,从而富集成矿,为一典型离子吸附型稀土矿床。

The ion-adsorbed rare earth deposit in Wan'an Mining area of Fujian Province has superior metallogenic conditions and great prospecting prospects.It is a large ion-adsorbed rare earth deposit discovered by the Eighth Geological Brigade of Fujian Province after more than two years of field geological work.The granite weathering crust in the mining area is relatively developed,with favorable ore-forming mother rock and favorable natural environmental conditions.The rare earth elements in the mother rock minerals are largely transformed into adsorbed rare earth ions in the weathering crust,thus enriching and mineralization,which is a typical ion-adsorbed rare earth deposit.
