The chemical composition of river sediments reflects bedrock geochemistry in the area of erosion and characterizes trend of weathering in the catchment area. The article presents data about chemical composition of Zeya River sediments. This river is one of the largest watercourses in the Amur River basin. The chemical composition of river sediments was analyzed by X-ray fluorescence spectrometry. Compared with the upper continental crust, the river sediments are depleted in almost all analyzed major elements. According to the analysis of major element the ratio, degree of weathering of river sediments in Middle Reach of the Zeya increases down the river. The chemical composition of studied river sediments is close to those in the rivers of northeastern China.
