摘　　要：武功山隆起区分布有花岗细晶岩型铌钽(锂)矿(化)点,研究表明,含矿细晶岩具富硅、铝、钠,贫铁、镁、钙的特征,具明显的Rb、Th、U、Ta、Nb、P、Hf正异常和Ba、K、Sr、Zr、Ti负异常,稀土总量较低,轻重稀土分异不明显,具显著的Eu负异常和明显的四分组效应。岩石属岩浆晚期高度分异演化的产物。The side part of Wugong mountain uplift is coated with granitic fine crystalline niobium tantalum(lithium)ore(mineralization)point,the results show that the ore-bearing fine crystalline rock has the characteristics of rich silicon,aluminum,sodium,poor iron,magnesium and calcium,and the trace elements have obvious Rb,Th,U,Ta,Nb,P,Hf positive anomaly and Ba,K,Sr,Zr,Ti negative abnormalities,The total amount of rare earth is low,the degree of differentiation and severity of rare earth is not obvious,and it has significant Eu negative abnormality,which has obvious four grouping effect.The rock belongs to the product of the late height differentiation evolution of magma.
