The authors have selected manganese nodules broadly representative of world oceanic areas. Approximately 1 gram of each manganese nodules was leached with 25-mi 6N HC1. Lead was extracted from the supernate by conventional anion exchange techniques, followed by a single dithizone extraction. Lead-isotope ratios were determined by mass spectrometry.
