天目山岩体于1∶5万区域地质调查时圈出铌地球化学异常，为查明其铌钽含矿性，通过化学测试、人工重砂、单矿物分析等手段，研究了岩体各单元铌钽含矿性、铌赋存状态及铌在矿物中的分配率。结果表明：①天目山岩体铌矿化发育于岩浆期，且位于岩体顶部，因而在天目山岩体周围寻找隐伏的岩株、岩瘤、岩枝等独立的小型碱性花岗岩体是寻找原生铌矿床的主要方向；②在岩体南侧的河流冲积物内寻找铌铁砂矿床，也有一定的远景。上述研究成果对于区内找矿工作有一定的参考价值。

The niobium geological anomaly of Tianmushan rock mass is obtained by conducting 1∶50 000 regional geological survey,in order to analyze the niobium tantalum ore-bearing potential of Tianmushan rock mass,the niobium tantalum ore-bearing potential,niobium occurrence state and niobium allocation rate of minerals are studied by the methods of chemical test,artificial sand and single mineral a-nalysis.The results show that:①the niobium mineralization of Tianmushan rock mass is developed in magmatic stage,and it is located at the top of rock mass,therefore,looking for the concealed rock strain, tumor and apophysis independent small alkaline granite rock mass around the Tianmushan rock mass is the main prospecting direction of native niobium ore deposit;②looking for the niobium iron ore deposit in the river alluvial materials in the south of Tianmushan rock mass can also has some prospecting vision. The above research results can have some reference value for the prospecting work in the research area.
