摘　　要：松树岗钽铌矿床位于钦杭东段北部成矿带之怀玉山钽铌多金属萤石-磷-滑石非金属成矿亚带内,为一隐伏花岗岩型稀有金属矿床。隐伏矿化岩体上部以钽矿化为主,下部以铌矿化为主,自上而下钽铌比值由大变小,钾铷比值由小变大,钽铌品位自上而下变化幅度小,两者呈反消长关系。文章在查阅历年地质找矿成果资料基础上,梳理总结了隐伏矿化岩体蚀变分带特征,旨在为区内寻找同类型矿床提供某些借鉴。Songshugang tantalum niobium deposit is located in the huaiyushan tantalum niobium polymetallic phosphorus talc nonmetallic metallogenic subzone of the eastern Qinhuangdao Hangzhou metallogenic belt,which is a concealed granite type rare metal deposit.Tantalum mineralization is dominant in the upper part of the concealed mineralized rock mass,the lower part is dominated by niobium mineralization,from above to below the tantalum niobium ratio changes from large to small,potassium rubidium ratio grow from small to big,from top to bottom the grade of tantalum and niobium varies slightly,there is a negative growth and decline relationship between the two.The article Based on the data of geological prospecting results over the years,summarized the characteristics of alteration zoning of concealed mineralized rock mass.the purpose is to provide some reference for the exploration of the same type of deposits in the area.
