据磷灰石裂变径迹具有在较低温度下能够迅火的特征，以及锆石径迹封闭温度在750℃以上的特点，研究同一矿石中两种不同单矿物卢生的裂变经迹与记录条件（径迹长度变化）。测定白云鄂博主矿成矿年龄数据属于海西中晚期，其值为3.3～4亿年，是改造后形成的时代。
According to the characteristics that apatite fission track can rapidly fire at lower temperature and the zircon track closed temperature is above 750 ℃, the fission track and record of two different single minerals in the same ore are studied Condition (track length change). The data of the mineralization age of the Bayan Obo host ore belongs to the middle and late Hercynian, with a value of 3.3-400 million years, which is an era formed after the reformation.
