Description and composition of Manganese deposits from the Mid-Atlantic Ridge, supplement to: Cronan, David S (1972): The Mid-Atlantic Ridge near 45 °N, XVII: Al, As, Hg, and Mn in Ferruginous Sediments from the Median Valley., Canadian Journal of Earth Sciences, 9(3), 319-323


Iron-rich sediments similar to those forming on other active mid-oceanic ridges have been found in the Median Valley of the Mid-Atlantic Ridge near 45 °N. The sediments are enriched in arsenic and mercury, and are thought to have formed largely as a result of submarine hydrothermal activity associated with the generation of new ocean floor at the ridge crest.
