| 摘 要： | 陕西紫阳县至岚皋县一带，分布着东西长160余千米、南北宽20～40千米的古生代碱中性岩浆岩带。通过对碱中性岩浆岩的地质特征及其铌钽等稀有金属含矿性调查和研究，认为该岩浆岩带是本区重要的铌钽成矿区，碱中性岩浆岩是本区主要铌钽含矿岩体，碱中性岩具铌钽稀有金属矿化，伴镧铈稀土金属矿化。

| Abstract: | The Paleozoic alkali intermediate magmatic belt, with a width of 20 40km from south to north and a length of 160 km from the east to the west, occurs in the Ziyang county and Langao county, Shaanxi Province. Investigation and researches on the geological characteristics of the alkalic intermediate magmatic rocks and the ore bearing properties of columbium and tantalum indicated that the magmatite belt in this area is an important mineralized zone of columbium and tantalum and the alkalic intermediate magmatic rocks are the major columbium tantalum bearing rock masses. The alkalic intermediate rocks contain the mineralization of columbium and tantalum, associated with the mineralization of rare earth metals of lanthanum and cerium. |
