Sediment samples obtained from the South Mid-Atlantic Ridge were analyzed for the major and trace elements by inductively coupled plasma atomic emission spectroscopy and inductively coupled plasma mass spectrometry.Results revealed that the contents of elements (e.g.,Fe,Mn,Cu,Zn,V,Co) were high in samples 22V-TVG10 and 26V-TVG05 from the sites near the hydrothermal areas,and low in sample 22V-TVG14,which was collected far from the hydrothermal areas.The contents of Ca,Sr and Ba in the samples showed opposite trends.A positive correlation between the concentrations of metallic elements (Cu,Zn,Co,Ni,Pb,V) and Fe in the samples were observed.These results are consistent with chemical evolution of the dispersing hydrothermal plume.
