Abstract : It is shown that the role of carbonated hydrothermal waters in the formation of deposits of nickel ores is very doubtful. Experimental findings shown that, while the possibility of certain quantities being carried off by carbonated hydrothermal waters cannot be denied, these are small quantities only, playing an insignificant role in natural processes. The accumulation of nickel ores is due basically to the surface processes of weathering and leaching of serpentinites by ground water containing carbon dioxide. The study of natural waters associated with serpentinites shows that these processes are actually taking place; hence there are no data to support a denial of the possibility of nickel ore accumulation in our present epoch. This conclusion is especially confirmed by finds, in recent years, of quite fresh semiliquid gels of nickel silicates.
