Distribution of elements in the world lignite average and its comparison with lignite seams of the North Bohemian and Sokolov basins

Abstract

Three data sets on sulfur and trace elements distribution were statistically treated to compare the lignite of the North Bohemian and Sokolov Basins with the world model lignite seams (world lignite average). During the early stages of the development ofthe North Bohemian Basin as well as the Sokolov Basin, the weathered rocks surrounding the depressions were exposed to erosion which allowed the weathered material to supply the basins with S, As and other elements.
