The postglacial sedimentary strata developed in north Jiangsu Coastal Plain mainly include littoral facies, offshoreneritic facies and tidal flat facies from the lower part to the upper part. Element geochemical study shows that the Changjiang and the Huanghe Rivers have a great influence on development of north Jiangsu Coastal Plain in postglacial period. During the early stage, the Changjiang's influence exceeded the Huanghe's, especially in the southern and middle part of north Jiangsu area, whereas the Huanghe River only transported small amount of matter and mainly influenced the northern part. After the postglacial transgression maximum, the Huanghe's influence was stronger than the Changjiang's, and only a narrow tributary of the Changjiang River transported limited amount of matter to Qianggang and Sancang area. The mainstream of the Changjiang River did not enter to sea via north Jiangsu area, so it did not carry much matter to form the tidal sand bodies either. During the last two thousand years, sediments of this area were mainly from the Huanghe River. Study also shows that element geochemical method is useful in provenance discrimination, because it can effectively avoid the influence of hydraulic sorting.
