Abstract: | The authors obtained the magnetostratigraphic division of Quaternary from the palaeomagnetic records of 7 cores taken from
the northern plain of Jiangsu Province. The depositional characteristics of this area are now described. The core near the
coastal region of the Yellow Sea showed the sedimentary rate was higher during Brunhes chron, but lower or nearly zero during
Matuyama chron. The core located in the middle of the northern plain of Jiangsu Province showed the depositional formation
was thin during Brunhes chron, but thicker in Matuyama. This depositional difference indicated obvious differences in the
tectonic units, geological basement, and depositional environments of the two periods. This study provides information for
the subdivision of Quaternary magnetostratigraphy.
