The geochemical behaviours of 26 elements in deep-sea drill core sediments from the Indian Ocean havebeen investigated with INAA, including Na, K, Ca, Sc, Cr, Fe, Co, Rb, Sr, Zr, Sb, Cs, Ba, La, Ce, Nd, Sm, Eu,Tb, Yb, Lu, Hf, Ta, Au, Th and U. Their distribution patterns with depth are also discussed. In terms of theenrichment factors of the respective elements, their residence times in the sea have been calculated by the leastsquares fitting and are compared with the previous results.
