Genesis of Ferromanganese Deposits: Hydrothermal Origin

  • Claude Lalou
Chapter
Part of the NATO Conference Series book series (NATOCS, volume 12)

Abstract

The recent discovery of active hydrothermal vents initiated a revolution in knowledge of the chemistry of the oceans and in the concept of a steady state ocean. The literature on known hydrothermal deposits, including metalliferous sediments, sulfides, barite, talc, iron silicates and manganese oxides is reviewed. Special consideration is given to studies of growth rates of manganese oxides in light of the new knowledge of hydrothermal processes.

The problem of the genesis of manganese nodules is also considered. It is shown that, owing to the flux of manganese presently delivered to the oceans by active hydrothermal vents, it is possible that the manganese forming the nodules has an hydrothermal origin. An hydrothermal source of manganese of the manganese nodules would answer such unresolved problems as why the nodules stay at the surface of sediments which accumulate at rates 1000 times faster than nodules are considered to form.
