- •
We report new paleomagnetic results from ~ 155 Ma Tiaojishan Formation in north China.
- •
We discuss the Late Mesozoic paleogeographic evolution of the major blocks in northeastern Asia.
- •
There has been ~ 1600 km latitudinal shortening between the Siberia and NCB after ~ 155 Ma.
- •
No significant vertical axis rotation between the middle and eastern areas of the Yanshan tectonic belt after ~ 155 Ma.
- •
Our study suggests that previously published Tiaojishan pole has not averaged out paleosecular variations.
