^(230)Th-^(238)U disequilibrium systematics reveal several important characteristics of the mantle source regions and petrogenesis of volcanic rocks in the presumed hot spots of Hawaii, Marion Island (Prince Edward hot spot), and Samoa. The (^(230)th/^(232)Th) activity ratios of lavas from these thr...
