摘　　要：广西容县浪水稀土矿为我国南方典型的离子吸附型稀土矿床,成矿母岩为印支期斑状黑云二长花岗岩,岩体规模大、分布广,成矿条件良好。矿床特征表明,具有工业意义的稀土矿体赋存于花岗岩风化壳全风化层中,矿石组分简单,属易选矿石。结合矿床地质特征及找矿经验,总结出矿区内离子吸附型稀土矿的找矿标志。Langshui REE(rare-earth element)deposit in Rongxian,Guangxi is one of the representative ion-adsorption type deposit.The ore-forming mother rocks are Indosinian porphyritic biotite monzonitic granite of a large scale and a wide distribution and with good metallogenic condition.Deposit features indicate that REE orebody with industrial significance hosts in the completely weathering layer of granite weathering crust.The ore is belonged to easy separation type with simple composition.After combination of geological characteristics of deposit and prospecting experience,this article points out the prospecting indicator of REE deposit of ion-adsorption type in this area.
