Abstract:
Nineteen chert samples from a continuous core of the DSDP (Leg 17, Hole 167) were analysed for Ge; in addition we analysed five samples from other cores. The ages range between Late Jurassic, and Late Eocene. The concentration of Ge changes with age from 0.87 ppm in the oldest samples to 0.23 ppm in the youngest (equivalent to a Ge/Si decrease from 0.00000072 to 0.00000019). The decrease in Ge/Si is well correlated with the 87Sr/86Sr ratio in sea water of the relevant age. The interpretation of this trend may reflect: (a) different levels of Ge/Si in sea water as a result of a different ratio between hydrothermal and riverine input, (b) a diagenetic trend in siliceous sediments, (c) recording (by radiolaria) a transition between a radiolaria dominated ocean (with relatively high Ge/Si ratios in sea water) and diatom domination or (d) a combination of the above.
