古地磁学的研究有力地促进了地球物理和地质科学的发展,尤其是它成为近代大地构造学中板块构造学说的有力支柱之后,更愈来愈被人们所重视.但是至今古地磁定向标本的采集仍局限在基岩出露的地表.为此,有许多人探讨用钻探岩心来确定岩层产状.但是,在赤平投影法中, Paleomagnetism research has strongly promoted the development of geophysics and geosciences, especially since it became a powerful pillar of plate tectonics theory in modern tectonism, more and more people pay attention to it.However, Acquisition is still confined to the surface of bedrock, and many people have therefore explored the use of drilling cores to determine rock formation.However, in the stereographic projection method,
