最近在福建永定大坪发现了特大型花岗斑岩型钽铌矿,为确定该矿床的成矿年龄和类型,利用LA-ICP-MS对该矿的铌铁矿进行了U-Pb年代学研究。结果显示,大坪铌铁矿的成矿年龄为183 Ma左右,该年龄与成岩年龄在误差范围内一致,表明华南地区存在早侏罗世花岗斑岩型钽铌成矿事件。大坪早侏罗世花岗斑岩型钽铌矿成矿时间和类型是对华南钽铌成矿研究的重要补充,为华南未来的钽铌找矿方向提供了新的思路。 |

In this work,the U-Pb chronology of columbite-tantalite group minerals (CGM) from the Daping super-large granite porphyry-type Ta-Nb ore deposit,which was recently discovered,in Yongding County,Fujian Province,have been conducted,in order to constrain mineralization age and type of the deposit. The results show that the mineralization age of the Daping Nb-Ta ore deposit is ca. 183 Ma which is consistent with the age of granite porphyry within analytical deviation, indicating that there is an Early Jurassic granite porphyry-type Ta-Nb mineralization event in South China. Therefore, it is believed that the discovery of the Daping Early Jurassic granite porphyry-type Ta-Nb ore deposit has provided an important supplement,in terms of mineralization time and metallogenic type,for studying the Nb-Ta mineralization in South China,and an new clue for prospecting Ta-Nb mineral resource in South China in future. |
