The work of this paper is to utilize the existing large paleomagnetic data set to perform the recently published Tauxe and Kent’s “Elongation/Inclination” statistic analyses for the three basins,and combined with other studies,to discuss the possible causes of the bias inclination in the region.Combined with other studies in the region,the authors believe that shallow inclinations of the sedimentary rocks are a common phenomenon of the northeast Tibetan Plateau,and the most likely cause of the inclination bias was due to syn-or post-depositional compaction of the sedimentary rocks.In addition,as these obtained shallow inclinations can be corrected by the E/I method,and the corrected inclinations match well with the expected inclinations from the Eurasia reference apparent polar wander paths,the authors believe that the north-southward shortening in the northeast Tibetan Plateau was insignificant since Neogene time,at least the amount of shortening is within the paleomagnetic study error range.
