摘要
This paper is concerned with the distibuticn of seme geochemical factors in sediments from Huanghe River Estuary，such as Eh,pH,Fe/Fe and the ratio of elementsp which show the characteristics of sedimentation in the estuary.According to the physical-chemistry principle the diagram of FeS2-Fe3O4-Fe2O3 system is made to indicate the coexistence and the tranform among minerals.
