Abstract: The eastern part of the Hebei plain is located at the mountain apron of the Yan Shan Mts. It is mainly made of accumulated plain of Luanhe, jiyunhe, Chaobai he and Yongdinghe. The thickness of Quaternary sediments increases gradually from north to south of the plain and it is 500-600M in the coastal region. This paper is based on the chemical analysis of 15 bore holes from the eastern Hebei plain. After sdusying the information, it is clear that the geochemical characteristics of the eastern Hebei plain have some connections with paleogeographical environments.The contents of chemical elements in the Quaternary sediment are respectively Fe 2.65%, Mn 395.4ppm, Cu 27.4 PPm, Zn.70.1 Ppm, Ni 36.1 ppm, Ca 2.4%, Mg 1.0%, Ti 0.4%, Sr 185 ppm, Ba 556 Ppm, B 46.3 ppm, Ga 18.6 ppm, V 100 ppm.The Mn content of sediment is one time less than that of the earth's crust and B content is three times more than the average content of the earth's crust The concentration of other elements is as much as the average content of the earth'crust. It is clear that comparing with tne content of the earth's crust, the chemical elements of Quaternary sediments in the e-astern part of the Hebei plain have no great difference. Elemental laws of movement and distribution and accumulationare controlled the various natural conditions.The natural environment of the eastern Hebei plain underwent a great change in Quaternary geological age. The climate during the Quaternary age had many times transformed from cold to warm. Therefore, the distribution of chemical elements have periodic change When tne weather was warmer and moister and the sea level elevated, the contents of chemical elements increased.
