87Sr/86Sr ratios in basalts from islands in the Indian Ocean

January 1, 1973

87Sr/86Sr ratios of basalts from islands in the Indian Ocean (0.7040) are higher than those of basalts dredged from the Mid-Indian Ocean Ridge (0.7034). The sources of the island basalts have apparently not been in equilibrium with the source of the ridge basalts for roughly 109 years. Both ridge and island basalts in the Indian Ocean are higher in87Sr/86Sr than are rocks from similar settings in the eastern Pacific.
