Abstract

Nine samples of corals collected from seven locations in the Saurashtra Coastal region of India were dated by 238U series disequilibrium methods. Of the three age groups (6000, 30,000, and 120,000 yr) reported for this region by the earlier studies of S. K. Gupta and B. S. Amin (1974, Marine Geology 16, 79–83), we could confirm only the 6000-yr group. Instead of a 120,000-yr group, we found a scatter of ages between 118,000 and 176,000 yr. There appears to be no evidence for 30,000-yr-old corals from this region.
