Abstract
HYDROTHERMAL alteration of basalts on the ocean floor has been reported to cause a general increase in the 87Sr/86Sr ratio of the basalts1,2. Results are presented here from Mull in the British Tertiary province which suggest strongly that hydrothermal alteration in such discrete magmatic centres may actually cause a reduction in the 87Sr/86Sr ratios of some basalts. Preliminary data indicate that the 143Nd/144Nd ratios are unaffected.
