摘　　要：宜春钽铌矿床位于钦杭成矿带东段,为一花岗岩型稀有金属矿床,矿区内发育Ta、Nb、Li、Rb、Cs、W、Sn等多种稀有金属矿化,并在岩浆作用的物理化学演化过程中形成垂向分带。本文通过对矿床特征、矿石特征等方面进行综合研究,并对稀有金属成矿条件进行分析探讨,指出矿床的形成与岩浆岩性质和岩浆演化密切相关,矿区正常花岗岩的高含量稀有元素、岩体顶部覆盖层的封闭作用等因素是形成矿床的关键。The Yichun tantalum-niobium deposit which is located in the eastern part of the Qinzhou-hangzhou me-tallogenic belt is a granite-type rare metal deposit.Various rare metal mineralizations such as Ta,Nb,Li,Rb,Cs,W,and Sn are developed in the deopsit,and vertical zoning is formed during the physical and chemical evolution of mag-matism.Based on the comprehensive study of the characteristics of the deposit,the mineral characteristics of the ore,the metallogenic conditions of rare metals have been dicussed.So it concluds that the formation of the deposit is closely related to the properties of magmatic rocks and magmatic evolution,and the high content of rare elements in the normal granite of the mining area and the sealing effect of the cap rock at the top of the rock mass are the keys to the formation of the deposit.
