✦ Synopsis

Strontium isotopic differences between the basalts from the East Pacific and the Chile Rises (0.7026-0.7035, average 0.7028) and abyssal hills (0.7025-0.7037, average 0.7033) suggest that these are produced from different source materials. A progressive increase of K/Rb with decrease in SIz~/Sr s6 ratio is interpreted in terms of relative depletion of dispersed elements in the source materials.
