| Abstract: | This paper deals with the distribution and source of Sr, Ti in ferromanganese nodules from the Pacific North region (7°-13°N, 178°-165°W) by analysing the Sr, Ti, Fe, Mn in the 80 ferromanganese nodules samples from 26 stations.The result shows that the average values of Sr, Ti in ferromanganese nodules are 0.040% and 0.64% respectively, increase with the decrease of the size of the ferromanganese nodules and the depth of sea water. There is a positive correlation between Sr and Ti. As the source of Sr, Ti mainly come from the deposition of Sr2+, Ti2+, the concentrations of Sr and Ti in the ferromanganese nodules in glossy surface exposed to sea water are higher than that in rough surface contacting the sediment. |
