Geochemical features of bottom waters in the zones of hydrothermal solution discharge in the mid-ocean ridges

摘要

In the near bottom layers, ore bearing hydrothermal solutions that are discharged on the ocean floor form complex dispersion aureoles (plumes), which are characterized by anomalous temperature and turbidity, as well as variations in density, Eh, pH, concentration of dissolved and suspended elements, and microbiological anomalies.
