Table of Contents:
  • Basal sediments cored above alkali basalt at Site 183 beneath the Aleutian Abyssal Plain include iron-rich clays, a geothite-bearing calcareous ironstone (23.8% Fe and 4.16% Mn, CaCO3-free), and a pyrite-bearing unfossiliferous aragonitic limestone with 1.95 per cent Sr. At Hole 192A, atop Meiji Guyot, the northernmost of the Emperor Seamounts, five meters of iron and manganese-enriched clays interlayered and diluted with chalk lie on extrusive alkali basalt pillow lavas beneath almost a kilometer of silts, clays, and diatomaceous oozes.
