Chemical composition of the bottom sediments obtained during Leg 138 of the Ocean Drilling Program was studied. Metalliferous sediments from the East Pacific Rise have lower average contents of Fe, Mn, Cu, Zn, and Ni, and higher average contents of Al and Ti as compared with the average contents of the metalliferous sediments of the Pacific Ocean. An attempt was made to study the spatial and temporal evolution of hydrothermal activity at the axis of the East Pacific Rise between 5 degrees S and 12 degrees N using the estimates of the rates of accumulation of hydrothermal iron in the sediments during the past 18 My.
