Features of trace metal distribution in the components of the ecosystem of the Lost City hydrothermal vent field (North Atlantic)

摘要

The biogeochemical features of the microelement distribution in the components of the ecosystem of the Lost City low-temperature field of the Mid-Atlantic Ridge are determined by the processes of serpentinization in ultrabasic rocks. In the Lost City biotope water, the concentration of trace metals (Fe, Mn, Zn, Cu, Cd, Ni, Cr, Pb, and As) is from n x 10 to 10(4) times higher than in the ocean water. The microelement content demonstrates a similar character of distribution in both types of calcite biominerals forming the carbonate matrix of the bivalve mussels Bathymodiolus and the scleractinian corals Anthozoa.
