摘要: Abstract A spectrochemical method for the determination down to 10 −4% Zn in numerous rocks and minerals has been developed. By means of fractionated distillation separation occurring silicates spinells from ZnS-bearing made possible. The result 130 analyses confirms figures given by Clarke-Washington (1924) (0.004%Zn) unpublished results V.M. Goldschmidt (1938) (≤ 0,004% Zn) abundance lithosphere.
