| 摘 要： | 经电镜分析发现,胜利油田主要产油(气)的第三系沉积岩中存在少量自生磷灰石,其特征为:具有自形或半自形;颗粒周围无风化晕圈;沿大的裂隙也无风化晕带。作者采用裂变径迹法对该自生磷灰石作了单颗粒年龄测定。实践证明,裂变径迹法测定年轻沉积地层的年龄是可行的。

| Abstract: | Fission track age of authigenic apatite from twentytwo samples of the Jiyang Depression have been determined and the results was compared with of paleomagnetic and K-Ar age data. The agreeement between the age data indicates that the method is feasible for age determination of sediments. The paper also suggested a new division of Guantao basal conglomerate. |
