| 摘 要： | 测量并分离出岩芯中的沉积剩磁,依据其在层面坐标系中的平均方向与岩石形成时的地磁场方向一致的原则,参照已发表的块体古地磁极移曲线(APWP)来计算赋存岩芯的隐伏地层产状,并给出了相应的计算方法及公式.

| Abstract: | Based on the principle that the average direction of depositional remanent magnetization(DRM) in the co-ordinates of strata surface is consistent with that of primary geomagnetic field and according to the confirmed polar data from paleomagnetic database, the spatial occurrence of buried layers is calculated. The detail mathematical solutions and formulas are also given in the paper. |
