Theoretically, paleopoles could be located by measuring
paleomagnetism in rocks of similar ages in different parts of the globe. However
chronological dating is insufficiently precise for this purpose for remote paleographic eras. In addition,
continental drift must be taken into an account. Only approximate locations can be assigned to paleopoles, with varying degree of reliability. Due to changing techniques and data selection and acceptance criteria, many "paleomagnetic poles" reported in the past would not be considered reliably determined according to the more recent state of the knowledge. ==Examples==
