Refined Estimates of the Biochemical Microelement Concentrations in Coal

Resumo

By determining the distribution function of the biochemical microelement concentrations on the basis of the gross concentrations in coal, better estimates of the concentrations in the paleophytomass may be obtained. The proposed method permits estimation of the biogeochemical concentrations at the significance level α = 0.05 for coal with low and relatively high microelement content. For coal with anomalous microelement content, α = 0.01.
