Lead distribution in coal and coaly shales in the Upper Silesian Coal Basin
Abstract
Lend in the Upper Silesian Coal Basin is mainly of inorganic origin. Its average content, in coal and coaly shales of the paralic series, is higher in the western part of the basin. In the limnic series, it is higher in the eastern part of the basin'. Great differentiation between the quantity of lead of organic and inorganic origin in individual beds in the Upper Silesian Coal Basin has been observed. A great contrast between the influence of organic and inorganic matter on the average content of this element has been ascertained. It testifies the great dynamics of lead accumulation and dispersion. Differences of lead content in the beds are correlated to the distribution of maximal extensive accumulation and dispersion of lead.Downloads
